Hormone Profiles

[Pcushion]

I have decided to start a thread that will talk about steroid hormones. All information will be pulled from: [FONT=&quot]William Llewellyn’s Book “Anabolics”.[/FONT] This thread will cover one steroid every day. If anyone wants to discuss a particular steroid please comment and “let’s talk about it” credit to MGK. I would love for readers to chime in so we can discuss opinions, personal experience, and results. I am going to start with good ole fashioned Nandrolone Decanoate.

[h=3]Description:[/h][FONT=&quot]Nandrolone decanoate is an injectable form of the anabolic steroid nandrolone. The decanoate ester provides a slow release of nandrolone from the site of injection, lasting for up to three weeks. Nandrolone is very similar to testosterone in structure, although it lacks a carbon atom at the 19th position (hence its other name, 19- nortestosterone). Like testosterone, nandrolone exhibits relatively strong anabolic properties. Unlike testosterone, however, its tissue-building activity is accompanied by weak androgenic properties. Much of this has to do with the reduction of nandrolone to a weaker steroid, dihydronandrolone, in the same androgen-responsive target tissues that potentate the action of testosterone (by converting it to DHT). The mild properties of nandrolone decanoate have made it one of the most popular injectable steroids worldwide, highly favored by athletes for its ability to promote significant strength and lean muscle mass gains without strong androgenic or estrogenic side effects.[/FONT]
[h=3]History:[/h][FONT=&quot]Nandrolone decanoate was first described in 1960,[SUP]433[/SUP] and became a prescription medication in 1962. It was developed by the international pharmaceuticals giant Organon, and sold under the brand name Deca-Durabolin. The name Deca-Durabolin denotes that the product contains a variant of Organon’s previously popular nandrolone injectable Durabolin (nandrolone phenylpropionate) using an ester of 10 carbon atoms. Organon expanded the market for nandrolone decanoate very rapidly following its release. Probably owing to a combination of its favorable properties and the large market presence of Organon, Deca-Durabolin soon became one of the most widely distributed anabolic steroids in the world.[/FONT]
[FONT=&quot]When first introduced to the United States, nandrolone decanoate (like Durabolin) was prescribed for a variety of ailments. Listed indications included pre- and postoperative use for building lean mass, osteoporosis, advanced breast cancer, weight loss due to convalescence or disease, geriatric states (general weakness and frailty), burns, severe trauma, ulcers, adjunct therapy with certain forms of anemia, and selective cases of growth and development retardation in children. The drug was initially sold in a dosage of only 50 mg/ml, owing to the very low recommended doses (usually 50-100 mg every 3-4 weeks). The drug was soon updated to include a 100 mg/ml version, reflecting the need for higher doses in some situations, particularly those with refractory anemia and advanced breast cancer. Later, a 200 mg/ml product was released by Organon as well.[/FONT]
[FONT=&quot]Although the drug had been applied favorably for a great many medical uses for approximately a decade, by the mid-1970’s the indicated uses for nandrolone decanoate were being refined, both in the U.S. and abroad. FDA approved prescribing information from 1975 lists nandrolone decanoate as “probably effective” as adjunct therapy in senile and postmenopausal osteoporosis, as well as for treating pituitary-deficient dwarfism until growth hormone is more available. It was also deemed “possibly effective” in aiding the retention of lean mass, controlling advanced breast cancer, and as adjunctive therapy for certain types of anemia. More time was given to investigate the potential “less than effective” uses of the drug.[/FONT]
[FONT=&quot]Modern (approved) medical applications for the drug are even more refined than they were in the mid-1970’s. In the United States, the drug is now only FDA approved for treating anemia, although it is often also used “off label” to preserve lean mass in HIV positive patients and others suffering from wasting diseases. Outside of the U.S., Organon seems to support the use of this drug mainly with patients suffering from severe anemia, osteoporosis, and advanced breast cancer. The Organon Deca-Durabolin brand of nandrolone decanoate remains widely available today, now distributed by new parent company Merck/MSD. In addition, nandrolone decanoate is produced as a generic drug in many countries, and is also manufactured under numerous other distinctive brand names, both for human and veterinary use.[/FONT]
[h=3]How Supplied:[/h][FONT=&quot]Nandrolone decanoate is widely available in human and veterinary drug markets. Composition and dosage may vary by country and manufacturer, but usually contain 25 mg/ml, 50 mg/ml, 100 mg/ml, or 200 mg/ml of steroid dissolved in oil.[/FONT]
[h=3]

[/h][h=3]Structural Characteristics:[/h][FONT=&quot]Nandrolone decanoate is a modified form of nandrolone, where a carboxylic acid ester (decanoic acid) has been attached to the 17-beta hydroxyl group. Esterified steroids are less polar than free steroids, and are absorbed more slowly from the area of injection. Once in the bloodstream, the ester is removed to yield free (active) nandrolone. Esterified steroids are designed to prolong the window of therapeutic effect following administration, allowing for a less frequent injection schedule compared to injections of free (unesterified) steroid. Nandrolone decanoate provides a sharp spike in nandrolone release 24-48 hours following deep intramuscular injection, which steadily declines to near baseline levels approximately two weeks later. The half-life of nandrolone decanoate is 7-12 days.[/FONT]

Acta Endocrinol 1985 supp 271 19-30.[/FONT]
[h=3]Side Effects (Estrogenic):[/h][FONT=&quot]Nandrolone has a low tendency for estrogen conversion, estimated to be only about 20% of that seen with testosterone.[SUP]434[/SUP] This is because while the liver can convert nandrolone to estradiol, in other more active sites of steroid aromatization such as adipose tissue nandrolone is far less open to this process.[SUP]435[/SUP]Consequently, estrogen-related side effects are a much lower concern with this drug than with testosterone. Elevated estrogen levels may still be noticed with higher dosing, however, and may cause side effects such as increased water retention, body fat gain, and gynecomastia. An anti-estrogen such as clomiphene citrate or tamoxifen citrate may be necessary to prevent estrogenic side effects if they occur. One may alternately use an aromatase inhibitor like Arimidex® (anastrozole), which more efficiently controls estrogen by preventing its synthesis. Aromatase inhibitors can be quite expensive in comparison to anti-estrogens, however, and may also have negative effects on blood lipids.[/FONT]
[FONT=&quot]It is of note that nandrolone has some activity as a progestin in the body.[SUP]436[/SUP] Although progesterone is a c-19 steroid, removal of this group as in 19-norprogesterone creates a hormone with greater binding affinity for its corresponding receptor. Sharing this trait, many 19-nor anabolic steroids are shown to have some affinity for the progesterone receptor as well.[SUP]437[/SUP] The side effects associated with progesterone are similar to those of estrogen, including negative feedback inhibition of testosterone production and enhanced rate of fat storage. Progestins also augment the stimulatory effect of estrogens on mammary tissue growth. There appears to be a strong synergy between these two hormones here, such that gynecomastia might even occur with the help of progestins, without excessive estrogen levels. The use of an anti-estrogen, which inhibits the estrogenic component of this disorder, is often sufficient to mitigate gynecomastia caused by nandrolone.[/FONT]
[h=3]Side Effects (Androgenic):[/h][FONT=&quot]Although classified as an anabolic steroid, androgenic side effects are still possible with this substance, especially with higher doses. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Nandrolone is a steroid with relatively low androgenic activity relative to its tissue-building actions, making the threshold for strong androgenic side effects comparably higher than with more androgenic agents such as testosterone, methandrostenolone, or fluoxymesterone. It is also important to point out that due to its mild androgenic nature and ability to suppress endogenous testosterone, nandrolone is prone to interfering with libido in males when used without another androgen.[/FONT]
[FONT=&quot]Note that in androgen-responsive target tissues such as the skin, scalp, and prostate, the relative androgenicity of nandrolone is reduced by its reduction to dihydronandrolone (DHN).[SUP]438 439[/SUP]The 5-alpha reductase enzyme is responsible for this metabolism of nandrolone. The concurrent use of a 5-alpha reductase inhibitor such as finasteride or dutasteride will interfere with site-specific reduction of nandrolone action, considerably increasing the tendency of nandrolone to produce androgenic side effects. Reductase inhibitors should be avoided with nandrolone if low androgenicity is desired.[/FONT]
[h=3]Side Effects (Hepatotoxicity):[/h][FONT=&quot]Nandrolone is not c-17 alpha alkylated, and not known to have hepatotoxic effects in healthy subjects. Liver toxicity is unlikely.[/FONT]
[h=3]Side Effects (Cardiovascular):[/h][FONT=&quot]Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Studies administering 600 mg of nandrolone decanoate per week for 10 weeks demonstrated a 26% reduction in HDL cholesterol levels.[SUP]440[/SUP] This suppression is slightly greater than that reported with an equal dose of testosterone enanthate, and is in agreement with earlier studies showing a slightly stronger negative impact on HDL/LDL ratio with nandrolone decanoate as compared to testosterone cypionate.[SUP]441[/SUP] Nandrolone decanoate should still have a significantly weaker impact on serum lipids than c-17 alpha alkylated agents. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.[/FONT]
[FONT=&quot]To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.[/FONT]
[h=3]Side Effects (Testosterone Suppression):[/h][FONT=&quot]All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Studies administering 100 mg per week of nandrolone decanoate for 6 weeks have demonstrated an approximate 57% reduction in serum testosterone levels during therapy. At a dosage of 300 mg per week, this reduction reached 70%.[SUP]442[/SUP] It is believed that the progestational activity of nandrolone notably contributes to the suppression of testosterone synthesis during therapy, which can be marked in spite of a low tendency for estrogen conversion.[SUP]443[/SUP] Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 2-6 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.[/FONT]
[FONT=&quot]The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects section of this book.[/FONT]
[h=3]Administration (Men):[/h][FONT=&quot]For general anabolic effects, early prescribing guidelines recommend a dosage of 50-100 mg every 3-4 weeks for 12 weeks. To treat renal anemia, the prescribing guidelines for nandrolone decanoate recommend a dosage of 100- 200 mg per week. The usual dosage for physique- or performance-enhancing purposes is the range of 200-600 mg per week, taken in cycles 8 to 12 weeks in length. This level is sufficient for most users to notice measurable gains in lean muscle mass and strength.It is often stated that nandrolone decanoate will exhibit its optimal effect (best gain/side effect ratio) at 2 mg per pound of bodyweight/weekly, although individual differences in response will likely dictate varying ideal doses for different users. Deca is not known as a very “fast” builder. The muscle-building effect of this drug is quite noticeable, but not dramatic. In general, one can expect to gain muscle weight at about half the rate of that with an equal amount of testosterone.[/FONT]
[FONT=&quot]Nandrolone decanoate is often combined with other steroids for an enhanced effect. A combination of 200-400 mg/week of nandrolone decanoate and 10-20 mg daily of Winstrol®, for example, is noted to greatly enhance the look of muscularity and definition when dieting/cutting. A strong non-aromatizing androgen like Halotestin® or trenbolone could also be used, again providing an enhanced level of hardness and density to the muscles. Being a moderately strong muscle builder, nandrolone can also be incorporated into bulk cycles with acceptable results. The classic “Deca and D-bol” stack (usually 200-400 mg of nandrolone decanoate per week and 15-25 mg of Dianabol per day) has been a bodybuilding basic for decades, and always seems to provide excellent muscle growth. A stronger androgen such as Anadrol 50® or testosterone could also be substituted, producing greater results, but with more water retention.[/FONT]
[h=3]Administration (Women):[/h][FONT=&quot]For general anabolic effects, early prescribing guidelines recommend a dosage of 50-100 mg every 3-4 weeks for 12 weeks. To treat renal anemia, the prescribing guidelines for nandrolone decanoate recommend a dosage of 50-100 mg per week. When used for physique- or performance-enhancing purposes, a dosage of 50 mg per week is most common, taken for 4-6 weeks. Although only slightly androgenic, women are occasionally confronted with virilization symptoms when taking this compound. Studies have demonstrated high tolerability (minor but statistically insignificant incidence of virilizing side effects) with a dose of 100 mg every other week for 12 weeks,[SUP]444[/SUP] while long-term studies (+12 months of use) have demonstrated virilizing side effects on a dose as low as 50 mg every 2-3 weeks.[SUP]445[/SUP] Should virilizing side effects become a concern, nandrolone decanoate should be discontinued immediately to help prevent their permanent appearance. After a sufficient period of withdrawal, the shorter-acting nandrolone Durabolin® might be considered a safer option. This drug stays active for only several days, greatly reducing the withdrawal time if indicated.[/FONT]
[h=3]Availability:[/h][FONT=&quot]Nandrolone decanoate continues to decline in prominence as a pharmaceutical product due to its limited use in clinical medicine. The drug is presently unavailable in the United States. Many Western nations continue to market the drug, though its production is increasingly being shifted to less regulated markets in Asia. Legitimate pharmaceutical forms are highly sought after on the black market, and thus subject to a great deal of counterfeiting.[/FONT]

[h=3]Description:[/h][FONT=&quot]Primobolan Depot is an injectable version of the steroid methenolone. This is the same constituent in Primobolan® orals (methenolone acetate), although here an enanthate ester is used to slow the steroid’s release from a site of injection. Methenolone enanthate offers a similar pattern of steroid release as testosterone enanthate, with blood hormone levels remaining markedly elevated for approximately 2 weeks. Methenolone itself is a moderately strong anabolic steroid with very low androgenic properties. Its anabolic effect is considered to be slightly less than Deca-Durabolin® (nandrolone decanoate) on a milligram for milligram basis. Methenolone enanthate is most commonly used during cutting cycles, when lean mass gain, not a raw mass increase, is the main objective.[/FONT]
[h=3]History:[/h][FONT=&quot]Methenolone was first described in 1960.[SUP]567[/SUP]Squibb introduced the drug (as methenolone enanthate) to the U.S. prescription drug market in 1962,[SUP]568[/SUP] sold for a very short time in the U.S. under the brand name of Nibal® Depot. Rights to the drug were given to Schering in West Germany (now Bayer) that same year, and Nibal® Depot soon disappeared from the U.S. market. Schering would sell methenolone enanthate under its new and ultimately most recognizable brand name, Primobolan® Depot. During the 1960s and ’70’s Primobolan Depot was available mainly in Europe, including such countries as Switzerland, Italy, Germany, Austria, Belgium, France, Portugal, and Greece.[/FONT]
[FONT=&quot]Schering maintained patent control over methenolone enanthate until the late 1970s. Before its patents expired, Schering had rigorously protected its intellectual property rights against any potential infringement, even in the U.S. market, where the company had not been marketing Primobolan Depot. Although methenolone enanthate has not been available for commercial sale in the United States for decades, it has technically retained its status as an FDA-approved drug.[/FONT]
[FONT=&quot]Primobolan Depot is typically prescribed as a lean tissue building anabolic agent, often used in cases where body wasting has occurred secondary to an operation, prolonged infection, wasting disease, aggressive corticosteroid administration, or convalescence. Some clinicians also prescribe this agent for treating osteoporosis, sarcopenia (the natural loss of muscle mass with aging), certain cases of chronic hepatitis, and breast carcinoma (usually as a secondary medication following other therapies). The steroid has also been used to promote weight gain in underweight premature infants and children in clinical studies, and was able to do so effectively and without signs of toxicity or undesirable effects.[SUP]569[/SUP] Athletes have long favored the combined strong anabolic, weak androgenic, and non-estrogenic nature of this drug, which makes it very desirable for building lean muscularity without side effects.[/FONT]
[FONT=&quot]Although Primobolan Depot demonstrated a good record of clinical safety, by the 1990s Schering had grown to be a multinational pharmaceutical giant, and was inevitably forced to reexamine its global steroid offerings in light of public concerns about sports doping. Primobolan Depot would be voluntarily withdrawn from most of the countries that had originally sold it. Today, the brand is sold in just a handful of countries including Spain, Turkey, Japan, Paraguay, and Ecuador. In spite of its limited supply, Bayer has remained (nearly) the exclusive producer of methenolone enanthate in the human drug business worldwide. In recent years, however, methenolone enanthate has shown up in a small number of other preparations, most from underground or export-only companies.[/FONT]
[h=3]How Supplied:[/h][FONT=&quot]All forms of Bayer Primobolan Depot are packaged in 1 mL glass ampules and contain 100 mg of methenolone enanthate. Composition and dosage of other brands may vary by country and manufacturer.[/FONT]
[h=3]

[/h][h=3]Structural Characteristics:[/h][FONT=&quot]Methenolone is a derivative of dihydrotestosterone. It contains one additional double bond between carbons 1 and 2, which helps to stabilize the 3-keto group and increase the steroid’s anabolic properties, and an additional 1-methyl group, which gives the steroid some protection against hepatic metabolism. Primobolan Depot makes use of methenolone with a carboxylic acid ester (enanthoic acid) attached to the 17-beta hydroxyl group. Esterified steroids are less polar than free steroids, and are absorbed more slowly from the area of injection. Once in the bloodstream, the ester is removed to yield free (active) methenolone. Esterified steroids are designed to prolong the window of therapeutic effect following administration, allowing for a less frequent injection schedule compared to injections of free (unesterified) steroid.[/FONT]
[h=3]Side Effects (Estrogenic):[/h][FONT=&quot]Methenolone is not aromatized by the body,[SUP]570[/SUP]and is not measurably estrogenic. Estrogen-linked side effects should not be seen when administering this steroid. Sensitive individuals need not worry about developing gynecomastia, nor should they be noticing any appreciable water retention with this drug. The increase seen with methenolone should be quality muscle mass, not the smooth bulk that often accompanies steroids open to aromatization. During a cycle, the user should additionally not notice strong elevations in blood pressure, as this effect is also related (generally) to estrogen and water retention. Methenolone is a steroid most favored during cutting phases of training, when water and fat retention are major concerns, and sheer mass not the central objective.[/FONT]
[h=3]Side Effects (Androgenic):[/h][FONT=&quot]Although classified as an anabolic steroid, androgenic side effects are still possible with this substance. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Methenolone is still a very mild steroid, however, and strong androgenic side effects are typically related to higher doses. Women often find this preparation an acceptable choice, observing it to be a very comfortable and effective anabolic.[/FONT]
[h=3]Side Effects (Hepatotoxicity):[/h][FONT=&quot]Methenolone is not considered a hepatotoxic steroid; liver toxicity is unlikely. Studies have failed to produce appreciable changes in markers of hepatic stress when the drug was given in therapeutic levels.[SUP]571[/SUP][/FONT]
[h=3]Side Effects (Cardiovascular):[/h][FONT=&quot]Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Methenolone should have a stronger negative effect on the hepatic management of cholesterol than testosterone or nandrolone due to its non-aromatizable nature, but a much weaker impact than c-17 alpha alkylated steroids. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.[/FONT]
[FONT=&quot]To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.[/FONT]
[h=3]Side Effects (Testosterone Suppression):[/h][FONT=&quot]All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention. At a moderate dosage of 100-200 mg weekly, methenolone should offer measurably less testosterone suppression than an equal dose of nandrolone or testosterone, due to its non-aromatizable nature. If used for less than eight weeks, hormonal recovery should not be a protracted experience.[/FONT]
[FONT=&quot]The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects page.[/FONT]
[h=3]Administration (Men):[/h][FONT=&quot]The prescribing guidelines for Primobolan Depot recommend a maximum dosage of 200 mg at the onset of therapy, and a continuing dosage of 100 mg every week. Prolonged administration protocols generally call for a 100 mg dosage every 1-2 weeks, or 200 mg every 2-3 weeks. The usual administration protocols among male athletes call for a 200-400 mg per week dosage, which is taken for 6 to 12 weeks, which is sufficient to promote very noticeable increases in lean muscle tissue. It is, however, not unusual to see the drug taken in doses as high as 600 mg per week or more, although such amounts are likely to highlight a more androgenic side of methenolone, as well as exacerbate its negative effects on serum lipids.[/FONT]
[FONT=&quot]Methenolone enanthate is often stacked with other (typically stronger) steroids in order to obtain a faster and more enhanced effect. During a dieting or cutting phase, a non-aromatizing androgen like Halotestin® or trenbolone can be added. The stronger androgenic component here should help to bring about an added density and hardness to the muscles. On the other hand, one might add another mild anabolic steroid such as stanozolol. The result of such a combination should again be a notable increase in muscle mass and hardness, which still should not be accompanied by greatly increased side effects. Methenolone enanthate is also used effectively during bulking phases of training. In such a scenario, the addition of testosterone or boldenone would prove quite effective for adding new muscle mass without presenting any notable hepatotoxicity to the user.[/FONT]
[h=3]Administration (Women):[/h][FONT=&quot]The prescribing guidelines for Primobolan Depot do not offer separate dosing recommendations for women, although it was indicated that women who were pregnant, or may become pregnant, should not use the drug. Female athletes generally respond well to a dosage of 50-100 mg per week. If both oral and injectable versions are available, the oral is often given preference, as it allows for greater control over blood hormone levels. Additionally, some women choose to include Winstrol® Depot (25 mg twice per week) or Oxandrolone (7.5-10 mg daily), and with it receive a greatly enhanced anabolic effect. Androgenic activity can be a concern with such dosing, however, and should be monitored closely. If stacking, it would be best to use a much lower starting dosage for each drug than if they were to be used alone. This is especially good advice if you are unfamiliar with the effect such a combination may have on you. A popular recommendation would also be to first experiment by stacking with oral Primobolan®, and later venture into the injectable if this is still necessary.[/FONT]

Anadrol is today’s topic!

Androgenic: 45
Anabolic: 320
Standard: Methyltestosterone (oral)
Chemical Names: 2-hydroxymethylene-17a-methyl-dihydrotestosterone, 4,5-dihydro-2-hydroxymethylene-17-alpha-methyltestosterone, 17alpha-methyl-2-hydroxymethylene-17-hydroxy-5alpha-androstan-3-one
Estrogenic Activity: high
Progestational Activity: not significant
​

[h=3]Description:[/h][FONT=&quot]Anadrol is a trade name for oxymetholone, a potent oral anabolic steroid derived from dihydrotestosterone. More specifically, it is a close cousin of methyldihydrotestosterone (mestanolone), differing only by the addition of a 2-hydroxymethylene group. This creates a steroid with considerably different activity than mestanolone, however, such that it is very difficult to draw comparisons between the two. For starters, oxymetholone is a very potent anabolic hormone. Dihydrotestosterone and mestanolone are both very weak in this regard, owing to the fact that these molecules are not very stable in the high enzyme (3-alpha hydroxysteroid dehydrogenase) environment of muscle tissue. Oxymetholone remains highly active here instead, as is reported in standard animal assay tests demonstrating a significantly higher anabolic activity than testosterone or methyltestosterone. Such assays suggest the androgenicity of oxymetholone is also very low (1/4th to 1/7th its anabolic activity), although real world results in humans suggest it is decidedly higher than that.[/FONT]
[FONT=&quot]Oxymetholone is considered by many to be the most powerful steroid commercially available. A steroid novice experimenting with this agent is likely to gain 20 to 30 pounds of massive bulk, and it can often be accomplished within 6 weeks of use. This steroid produces a lot of water retention, so a good portion of this gain is going to be water weight. This is often of little consequence to the user, who may be feeling very big and strong while taking oxymetholone. Although the smooth look that results from water retention is often not attractive, it can aid quite a bit to the level of size and strength gained. The muscle is fuller, will contract better, and is provided a level of protection in the form of extra water held into and around connective tissues. This will allow for more elasticity, and will hopefully decrease the chance for injury when lifting heavy. It should be noted, however, that a very rapid gain in mass might also place too much stress on your connective tissues. The tearing of pectoral and biceps tissue is commonly associated with heavy lifting while massing up on steroids, and oxymetholone is a common offender. There can be such a thing as gaining too fast.[/FONT]
[h=3]History:[/h][FONT=&quot]Oxymetholone was first described in 1959.[SUP]384[/SUP]The agent was released in the United States as a prescription drug during the early 1960’s, sold under the brand names Anadrol-50 (Syntex) and Androyd (Parke Davis & Co.). Syntex developed the agent, and would hold patent rights to it until their expiration many years later. The drug was originally approved for use in conditions where anabolic action was necessary. Indicated uses included geriatric debilitation, chronic underweight states, pre- and postoperative preservation of lean mass, convalescence from infection, gastrointestinal disease, osteoporosis, and general catabolic conditions. The recommended dose for such uses was usually 2.5 mg three times per day. The drug was originally supplied in a 2.5 mg, 5 mg, or 10 mg tablet.[/FONT]
[FONT=&quot]In spite of the many potential therapeutic uses or a strong anabolic activity of this drug, the FDA soon strictly narrowed the indicated uses of oxymetholone. By the mid-1970’s, the drug was FDA approved only for the indicated treatment of anemia characterized by deficient red blood cell (RBC) production. Admittedly the stimulation of erythropoiesis is an affect that is characteristic of nearly all anabolic steroids, which as a group tend to increase RBC concentrations. Oxymetholone, however, seemed fairly reliable in this regard; demonstrating an increase in erythropoietin levels as much as 5 fold.[SUP]385[/SUP] This has led to its adoption for this relatively new medical use, as well as the institution of a higher (50 mg) dosage with the updated Anadrol-50 product, necessary for a stronger effect on RBC count. The Parke Davis item would not be brought up to the higher dosage, however, and was discontinued.[/FONT]
[FONT=&quot]Recent years have brought fourth a number of new treatments for anemia, most notably Epogen (recombinant erythropoietin) and related erythropoietic peptides. These drugs directly mimic the body’s natural red blood cell producing hormone, and as such provide a much more focused form of therapy, with less of the unrelated side effects one would have to endure with the use of a strong androgen. Although Anadrol was once viewed as an effective drug for this purpose, sales were now dropping. Financial disinterest finally prompted Syntex to halt production of the U.S. Anadrol 50 in 1993, which was around the same time they decided to drop this item in a number of foreign countries. Plenastril from Switzerland and Austria were dropped; following soon was Oxitosona from Spain. During the mid-1990’s, many Athletes feared oxymetholone was on the way out for good.[/FONT]
[FONT=&quot]In July 1997, Syntex sold all rights to Anadrol-50 in the U.S., Canada, and Mexico to Unimed Pharmaceuticals. Unimed reintroduced Anadrol-50 to the U.S. market in 1998, this time targeting HIV/AIDS patients. Patients with HIV are commonly anemic, often caused by the disease itself, opportunistic infections, or the antiretroviral drugs used to treat the disease. The anemia in HIV patients is typically categorized by impaired red blood cell production in bone marrow, the FDA approved indication for oxymetholone use. Adding to this, oxymetholone was showing great promise in studies combating HIV associated wasting. Unimed soon initiated Phase II/III trials with Anadrol for HIV wasting syndrome, and continued to research its use for treating such things as chronic obstructive pulmonary disease and lipodystrophy (a disorder characterized by a selective loss of body fat, insulin resistance, diabetes, high triglycerides levels, and a fatty liver).[/FONT]
[FONT=&quot]In April 2006, Solvay Pharmaceuticals (parent company of Unimed) sold the rights to Anadrol-50 to Alaven Pharmaceutical, LLC. Alaven continues to market the drug in the United States, although given the transition it is uncertain what additional uses the company plans to pursue with oxymetholone. At the present time the only FDA approved indication remains that of treating red blood cell deficient anemia. Syntex seems to have removed itself from the oxymetholone market globally, discontinuing product or transferring license to other companies whenever possible. Oxymetholone remains available outside of the United States, although it is mostly still sold in smaller and less tightly regulated markets.[/FONT]
[h=3]How Supplied:[/h][FONT=&quot]Oxymetholone is available in select human drug markets. Composition and dosage may vary by country and manufacturer. Most brands contain 50 mg of steroid per tablet.[/FONT]
[h=3]

[/h][h=3]Structural Characteristics:[/h][FONT=&quot]Oxymetholone is a modified form of dihydrotestosterone. It differs by 1) the addition of a methyl group at carbon 17-alpha, which helps protect the hormone during oral administration, and 2) the introduction of a 2-hydroxymethylene group, which inhibits its metabolism by the 3-hsd enzyme and greatly enhances the anabolic and relative biological activity of methyldihydrotestosterone.[/FONT]
[h=3]Side Effects (Estrogenic):[/h][FONT=&quot]Oxymetholone is a highly estrogenic steroid. Gynecomastia is often a concern during treatment, and may present itself quite early into a cycle (particularly when higher doses are used). At the same time water retention can become a problem, causing a notable loss of muscle definition as both subcutaneous water retention and fat levels build. To avoid strong estrogenic side effects, it may be necessary to use an anti-estrogen such as Nolvadex® or Clomid®.[/FONT]
[FONT=&quot]It is important to note that oxymetholone does not directly convert to estrogen in the body. This steroid is a derivative of dihydrotestosterone, and as such cannot be aromatized. Anti-aromatase compounds such as Cytadren and Arimidex® will, likewise, not effect the relative estrogenicity of this steroid. Some have suggested that the high level of estrogenic activity in oxymetholone is actually due to the drug acting as a progestin, similar to nandrolone. The side effects of both estrogens and progestins can be very similar, which might have made this explanation a plausible one. There was a medical study examining the progestational activity of oxymetholone, however, and it determined that there was no such activity present.[SUP]386[/SUP] With such findings, it seems most plausible that oxymetholone can activate the estrogen receptor, similar to, but more profoundly than, the estrogenic androgen methandriol.[/FONT]
[h=3]Side Effects (Androgenic):[/h][FONT=&quot]Although oxymetholone is classified as an anabolic steroid, androgenic side effects are still possible with this substance. These may include bouts of oily skin, acne, and body/facial hair growth. Higher doses are more likely to cause such side effects. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are additionally warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. While Anadrol is classified as an anabolic steroid, it does retain a notable androgenic component.[/FONT]
[FONT=&quot]It is interesting to note that oxymetholone does exhibit some tendency to convert to dihydrotestosterone in the body, although this does not occur via the 5-alpha reductase enzyme. Oxymetholone is already a dihydrotestosterone-based steroid, so no such alteration can take place. Aside from the added c-17 alpha alkylation (discussed below), oxymetholone differs from DHT only by the addition of a 2-hydroxymethylene group. This grouping can be removed metabolically, reducing oxymetholone to the potent androgen 17alpha-methyl dihydrotestosterone (mestanolone).[SUP]387[/SUP] There is little doubt that this biotransformation contributes at least on some level to the androgenic nature of this steroid. Note that since 5-alpha reductase is not involved, the relative androgenicity of oxymetholone is not affected by the concurrent use of finasteride or dutasteride.[/FONT]
[h=3]Side Effects (Hepatotoxicity):[/h][FONT=&quot]Anadrol is a c17-alpha alkylated compound. This alteration protects the drug from deactivation by the liver, allowing a very high percentage of the drug entry into the bloodstream following oral administration. C17-alpha alkylated anabolic/androgenic steroids can be hepatotoxic. Prolonged or high exposure may result in liver damage. In rare instances life-threatening dysfunction may develop. It is advisable to visit a physician periodically during each cycle to monitor liver function and overall health. Intake of c17-alpha alkylated steroids is commonly limited to 6-8 weeks, in an effort to avoid escalating liver strain.[/FONT]
[FONT=&quot]Oxymetholone has a saturated A-ring, which slightly reduces its relative hepatotoxicity.[SUP]388[/SUP]Still, this agent, particularly at the doses commonly used, can present substantial hepatotoxicity to the user. Studies administering 50 mg or 100 mg daily to 31 elderly men for 12 weeks produced significant increases in liver enzymes (transaminases AST and ALT) only in patients taking 100 mg. A second study administering 50 mg daily to 30 patients for up to and exceeding one year (in some patients) has demonstrated elevations in y-glutamyltransferase (GGT) in 17% of patients, significant increases in bilirubin in 10%, and serum albumin increases in 20%.[SUP]389[/SUP] One patient developed a liver tumor that could have been peliosis hepatitis, a life-threatening adverse event characterized by blood filled cysts in the liver. A small number of other cases of peliosis hepatitis have been linked to oxymetholone, suggesting the potential for hepatotoxicity should still be carefully considered before use.[/FONT]
[FONT=&quot]The use of a liver detoxification supplement such as Liver Stabil, Liv-52, or Essentiale Forte is advised while taking any hepatotoxic anabolic/androgenic steroids.[/FONT]
[h=3]Side Effects (Cardiovascular):[/h][FONT=&quot]Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.[/FONT]
[FONT=&quot]Oxymetholone has a strong effect on the hepatic management of cholesterol due to its structural resistance to liver breakdown and route of administration. Studies administering 50 mg or 100 mg daily to a group of elderly men for 12 weeks have demonstrated insignificant increases in LDL cholesterol, accompanied by very significant (dramatic) suppressions of HDL cholesterol (reduced 19 and 23 points in the 50 mg and 100 mg groups, respectively).[SUP]390[/SUP] The use of oxymetholone should be undertaken only after careful consideration in people with high cholesterol or a familial history of heart disease.[/FONT]
[FONT=&quot]To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.[/FONT]
[h=3]Side Effects (Testosterone Suppression):[/h][FONT=&quot]All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Without the intervention of testosterone stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.[/FONT]
[FONT=&quot]Note that when discontinuing Anadrol, the crash can be as equally powerful as the on-cycle results. To begin with, the level of water retention will quickly diminish, dropping the user’s body weight dramatically. This should be expected, and not of much concern. What is usually of most concern is restoring endogenous testosterone production with a proper PCT program (see: Post Cycle Therapy). Before going off, some alternately choose to first switch over to a milder injectable like Deca-Durabolin® for several weeks. This is in an effort to “harden up the new mass,”and can prove to be an effective practice, at least from a mental standpoint. A drop of weight is likely when making the switch, although the end result is still often viewed as allowing the retention of more (quality) muscle mass. It is sort of stepping down, first off the water retention, and weeks later finally off the hormones. Remember ancillaries though, as testosterone production will not be rebounding during Deca therapy.[/FONT]
[FONT=&quot]The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects section of this book.[/FONT]
[h=3]Administration (General):[/h][FONT=&quot]Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability.[SUP]408[/SUP] This is caused by the fat-soluble nature of steroid hormones, which can allow some of the drug to dissolve with undigested dietary fat, reducing its absorption from the gastrointestinal tract. For maximum utilization, this steroid should be taken on an empty stomach.[/FONT]
[h=3]Administration (Men):[/h][FONT=&quot]Early prescribing guidelines for oxymetholone recommended a dosage of 2.5 mg three times per day to reverse the wasting process and provide lean body mass gain. Doses as high as 30 mg were employed in some cases. Current prescribing guidelines recommend a dosage of 1-5 mg per kilogram of bodyweight per day for treating anemia, although indicate that a dose of 1-2 mg/kg is typically sufficient. A 175-pound person would take approximately 150 mg per day at the 2 mg/kg dosage level. In some other countries, it is recommended to limit the dosing of oxymetholone to 100 mg per day. Therapy is usually given for a minimum of three to six months. When used for physique- or performance-enhancing purposes, an effective oral daily dosage would fall in the range of 25-150 mg, taken in cycles lasting no more than 6-8 weeks to minimize hepatotoxicity. This level is sufficient for dramatic increases in muscle mass and strength. Higher doses are rarely administered due to the strong estrogenic nature of the drug, as well as the high potential for hepatotoxicity. When used for physique- or performance-enhancing purposes, an effective oral daily dosage would fall in the range of 25-150 mg, taken in cycles lasting no more than 6-8 weeks to minimize hepatotoxicity. This level is sufficient for dramatic increases in muscle mass and strength. Higher doses are rarely administered due to the strong estrogenic nature of the drug, as well as the high potential for hepatotoxicity.[/FONT]
[h=3]Administration (Women):[/h][FONT=&quot]Prescribing information for oxymetholone in the U.S. makes no distinction with the dose for females. Oxymetholone is generally not recommended for women for physique- or performance-enhancing purposes due to its very strong nature and tendency to produce virilizing side effects.[/FONT]
[h=3]Availability:[/h][FONT=&quot]Pharmaceutical preparations containing oxymetholone are fairly limited. The legitimate supply seems to be scattered into isolated markets of Europe, Asia, and the Americas. Most of the supply for this drug comes in the form of underground and export-only products.[/FONT]

 

[Pcushion]

Sorry for the delayed post. I have had a super busy two days. So I chose to talk about Oral Testosterone Undecanoate. This is a perfect example of a steroid that should remain in the medical field and not be bodybuilding or powerlifting in my opinion.



Androgenic 100
Anabolic 100
Standard Testosterone (Standard)
Chemical Names 4-androsten-3-one-17beta-ol, 17beta-hydroxy-androst-4-en-3-one
Estrogenic Activity moderate
Progestational Activity low
Description:

Andriol is an oral testosterone preparation that contains 40 mg of testosterone undecanoate (in an oil base) in a soft gelatin capsule. This drug is very different than most oral anabolic steroids, which are usually c-17 alpha alkylated to survive first pass metabolism through the liver. Instead, esterification and suspension in oil allows the testosterone undecanoate in Andriol® to be partially absorbed through the lymphatic system along with dietary fat. This bypasses the destructive first-pass through liver, providing sustained physiological levels of testosterone to the body. The actual oral bioavailability of Andriol is estimated to be approximately 7%. In design, this steroid is essentially a non-toxic and orally active testosterone, intended to provide a unique alternative to testosterone injections and other hepatotoxic oral anabolic/androgenic steroids.
History:

Oral testosterone undecanoate capsules were developed by international drug giant Organon (now Merck/MSD), and first introduced into clinical trials during the early 1980’s. The drug was soon approved for use as a prescription agent in a number of countries around the globe, generally under the Andriol brand name, although Organon has also marketed it as Androxon, Panteston, Restandol, Undestor, and Virigen in certain markets. This drug preparation is indicated for testosterone replacement therapy in males with conditions associated with insufficient endogenous androgen production. Although there is a large market for androgen replacement drugs in the United States, the drug is not approved for sale on the U.S. market. It has been approved as a prescription agent in the bordering markets of Mexico and Canada, however.
In 2003, Organon began replacing its Andriol products with Andriol® Testocaps®. The new formulation improves on the storage limitations of the original Andriol preparations, which needed to be kept under refrigeration at the pharmacy. The drug was stored at room temperature once dispensed, as the product needed to be consumed at room temperature. Outside of refrigeration, however, the drug functionally had only a 3-month shelf life. The new Andriol Testocaps are designed to always be stored at room temperature, and have a shelf life of 3 years. The new formulation is considered to be bioequivalent to the older version, and can be substituted in patients without any change in dosage.[SUP]417[/SUP] Given the handling advantages and bioequivalency, it is likely that the new Testocaps will slowly come to replace all of the older Andriol preparations.
In spite of its wide availability, Andriol has never been a popular item among athletes. This is likely due to the high relative cost of the drug, and its low potency compared to other pharmaceutical preparations, particularly injectable testosterone compounds and the more potent synthetic oral anabolic steroids. Still, Andriol remains a product of choice among those athletes not interested in using injectable medications and preferring to avoid the greater risks of hepatotoxicity and lipid alterations inherent in c-17 alpha alkylated orals. Today, decades after its initial release, Merck/MSD remains the sole global producer of prescription oral testosterone undecanoate. Andriol itself has maintained a prominent share of the global hormone replacement market since the 1990’s.
How Supplied:

Oral testosterone undecanoate preparations are available in various human drug markets. The older formulations supply 40 mg of testosterone undecanoate in oleic acid, contained in small soft gelatin capsules. Andriol Testocaps supplies 40 mg of testosterone undecanoate in castor oil and propylene glycol monolaurate, contained in small soft gelatin capsules. Packaging is commonly as bottles of 30 or 60 capsules, or foil/plastic strips of 10 capsules. Subtracting the ester weight, each 40 mg Andriol capsule contains 25.3mg of (base) testosterone.

Structural Characteristics:

Andriol® contains testosterone that has been modified with the addition of carboxylic acid ester (undecanoic acid) at the 17-beta hydroxyl group. The esterified hormone is more fat soluble than base (free) testosterone, and has been dissolved in oil and encapsulated for oral administration. Significant absorption of oral testosterone undecanoate takes place through the lymphatic route, bypassing the first pass through the liver. Andriol® is designed to provide a peak in testosterone levels several hours after administration, and with repeated dosing maintain physiological concentrations for 24 hours.

Side Effects (Estrogenic):

Testosterone is readily aromatized in the body to estradiol (estrogen). The aromatase (estrogen synthetase) enzyme is responsible for this metabolism of testosterone. Elevated estrogen levels can cause side effects such as increased water retention, body fat gain, and gynecomastia. Testosterone is considered a moderately estrogenic steroid. Exceeding therapeutic doses will increase the likelihood of estrogenic side effects. In such cases, an anti-estrogen such as clomiphene citrate or tamoxifen citrate is commonly applied to prevent estrogenic side effects. One may alternately use an aromatase inhibitor like Arimidex® (anastrozole), which more efficiently controls estrogen by preventing its synthesis. Aromatase inhibitors can be quite expensive in comparison to anti-estrogens, however, and may also have negative effects on blood lipids.
Side Effects (Androgenic):

Testosterone is the primary male androgen, responsible for maintaining secondary male sexual characteristics. Taking oral testosterone undecanoate in doses exceeding normal therapeutic levels is likely to produce androgenic side effects including oily skin, acne, and body/facial hair growth. Men with a genetic predisposition for hair loss (androgenetic alopecia) may notice accelerated male pattern balding. Women are warned of the potential virilizing effects of anabolic/androgenic steroids, especially with a strong androgen such as testosterone. These may include deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. In androgen-responsive target tissues such as the skin, scalp, and prostate, the high relative androgenicity of testosterone is dependant on its reduction to dihydrotestosterone (DHT). The 5-alpha reductase enzyme is responsible for this metabolism of testosterone. The concurrent use of a 5-alpha reductase inhibitor such as finasteride or dutasteride will interfere with site-specific potentiation of testosterone action, lowering the tendency of testosterone drugs to produce androgenic side effects. It is important to remember that anabolic and androgenic effects are both mediated via the cytosolic androgen receptor. Complete separation of testosterone’s anabolic and androgenic properties is not possible, even with total 5-alpha reductase inhibition.
Side Effects (Hepatotoxicity):

Testosterone does not have hepatotoxic effects; liver toxicity is unlikely. One study examined the potential for hepatotoxicity with high doses of oral testosterone by administering 400 mg of the hormone per day (2,800 mg per week) to a group of male subjects. The hormone was given daily for 20 days, and produced no significant changes in liver enzyme values including serum albumin, bilirubin, alanine-amino-transferase, and alkaline phosphatases.[SUP]418[/SUP]No study in which liver enzymes were examined has demonstrated an adverse hepatotoxic effect from Andriol, including an examination of patients on continuous therapy for 10 years.[SUP]419[/SUP]
Side Effects (Cardiovascular):

Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Anabolic/androgenic steroids may also adversely effect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction. Therapeutic doses of oral testosterone undecanoate used to correct insufficient androgen production in otherwise healthy aging men are unlikely to increase atherogenic risk, and may actually improve lipid profiles and cardiovascular risk factors.[SUP]420[/SUP]
To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.
Side Effects (Testosterone Suppression):

All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Testosterone is the primary male androgen, and offers strong negative feedback on endogenous testosterone production. Testosterone-based drugs will, likewise, have a strong effect on the hypothalamic regulation of natural steroid hormones. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.
The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects page.
Administration (General):

Andriol should always be taken with meals, preferably containing a moderate fat content (20 grams) to maximize lymphatic absorption. Very low bioavailability has been reported when taken in the fasted state. The total daily dosage should be divided into a minimum of two applications, taken in the morning and evening, to maintain more consistent elevations of serum testosterone.
Administration (Men):

For the treatment of low androgen levels, prescribing guidelines for Andriol recommend an initial dosage of 120-160 mg daily for 2-3 weeks. Based on the level of effect, a daily maintenance dosage of 40-120 mg is usually continued at this point. For bodybuilding purposes, higher doses would be required to reach strong supraphysiological levels of testosterone. This would generally call for a minimum dosage of 240-280 mg per day (6-8 capsules), taken in cycles of 6-8 weeks. A more common effective dosage, however, would fall in the range of 400-480 mg (10 to 12 capsules) per day. These doses can be quite costly given the relative price of Andriol preparations, making injectable testosterones much more cost effective and popular. Given the relative low potency of Andriol, when taken by athletes it is most commonly used in combination with other agents. Testosterone drugs are ultimately very versatile, and can be stacked with many other anabolic/androgenic steroids depending on the desired effect.
Administration (Women):

Andriol is not prescribed to women in clinical medicine. This drug is not recommended for women for physique or performance-enhancing purposes due to its strong androgenic nature and tendency to produce virilizing side effects.
Availability:

Oral testosterone undecanoate remains widely available. It is produced almost exclusive by or under license from Organon (now Merck/MSD).

 

[Pcushion]

Trenbolone is today’s topic, more specifically the acetate version. Guys I love Trenbolone it’s by far my absolute favorite steroid.

Androgenic 500
Anabolic 500
Standard Nandrolone acetate
Chemical Name 17beta-Hydroxyestra-4,9,11-trien-3-one
Estrogenic Activity none
Progestational Activity moderate
Description:

Trenbolone was first synthesized in 1963 by Velluz et al.[SUP]503[/SUP] The drug appears to have been an early development project of Roussel-UCLAF. By the early 1970’s, it was being sold as an injectable (trenbolone acetate) in England by Hoechst as Finajet, and in France as Finaject by Roussel. Roussel AG in Germany was parent to both companies. Trenbolone acetate is a drug of veterinary medicine, although a longer-acting ester of trenbolone (see: Parabolan) was once sold for human consumption as well. Trenbolone acetate is used, almost exclusively, to increase the rate of weight gain and improve feed efficiency of cattle shortly before slaughter. Essentially, the drug is utilized to increase product profitability, as measured in total pounds of salable meat. It is generally used right up to the point of slaughter, with no withholding period. Meat products sold in many areas of the world will often contain small amounts of residual trenbolone metabolites as a result of this practice.
Trenbolone acetate first became popular among U.S. bodybuilders during the 1980’s, a time when the drug was being smuggled in from Europe in high volume. It was identified (rightly so) as a powerful anabolic and androgenic agent, and quickly became a drug of choice among American competitive bodybuilders. Although extremely hot for a brief period of time, the supply of trenbolone acetate ended abruptly in 1987, as Hoechst-Roussel decided to voluntarily discontinue sale of all injectable forms of this medication. Although unconfirmed, the growing public concern about sports doping likely had much to do with this decision, as the discontinuation of “controversial” steroids was very common during the late 1980’s and early 1990’s. This event marked the end of legitimate medicines containing trenbolone acetate for injection.
Around the same time as we were seeing the demise of Finajet and Finaject, Hoechst-Roussell was introducing trenbolone acetate to the U.S. market as Finaplix cattle implant pellets. This came subsequent to the FDA’s approval for such products in 1987 . The pellets were designed for subcutaneous implantation into the ear of the cattle with a handheld implant gun, and are far too large to be implanted in humans without minor surgery. Remarkably, trenbolone acetate pellets are exempt from U.S. controlled substance laws. This is presumably to make it easy and affordable for livestock owners to have access to the growth-promoting agent. If a veterinarian were needed every time these products were to be used, they might be too troublesome or cost prohibitive to consider. Admittedly, since these products come in the form of pellets, they are not in a form suitable for human consumption either, making their exemption seem a little more reasonable than at first glance.
Human administration of Finaplix pellets can be difficult to accomplish, but it is still widely done. Most commonly, two to four implant pellets are ground up and mixed with a 50/50 water and DMSO solution, which is applied to the skin daily. This home-brew transdermal mix is effective, but also tends to carry a strong odor of garlic (an effect of the DMSO). Others simply grind up a few pellets with the back of a spoon and inhale (snort) them. Here, the drug enters the blood stream through the mucous membrane, a poor but still useful means of delivery for steroid hormones. Those who have tried this often claim it is not as irritating as they had imagined it would be. Alternately, some athletes opt to simply consume the drug orally. Although not an ideal mode of delivery, trenbolone displays a moderate level of oral bioavailability, and can be used in this manner given adequate dosing.
More adventurous individuals have made it a practice to mix their own injections with Finaplix. The pellets are ground into a fine powder (usually anywhere from 2 to 6 pellets), and then are added to sterile water, propylene glycol, or an oil-based injectable steroid or veterinary vitamin. This is usually repeated twice weekly, although some do manage to undertake this practice more frequently. Since this is not being done in a controlled sterile environment, however, one is obviously risking infection (or worse) by doing this. Starting in the late 1990’s, some stores began selling kits that contain all the necessary ingredients to separate the binders from the active steroid and brew a relatively pure injectable. These kits have grown in popularity over the years, and are usually reviewed favorably, although are not considered a substitute for sterile pharmaceutical medications.
Finaplix® is presently available in the U.S. and some markets abroad, although it is now being sold by Intervet instead of Hoechst-Roussel Agri-vet. This product comes in two forms, Finaplix-H and Finaplix-S, which denotes if the product was intended for a Heifer or a Steer respectively. The total dosages of both products are different, with the “H” version containing 100 20 mg trenbolone acetate pellets (2,000 mg) and the “S” version only 70 (1,400 mg). Ivy Animal Health (U.S.) has introduced two competing products of equivalent makeup as well, sold as Component-TH and Component-TS. There are also the Revalor and Synovex+ brands that contain trenbolone acetate with an added (usually unwanted) dose of estrogen. Additionally, although no other legitimate medicines containing trenbolone acetate exist, the drug is produced (for injection and oral use) by a number of export and underground steroid manufacturers.
How Supplied:

Trenbolone acetate is available in select veterinary drug markets. It generally comes in the form of implant pellets containing 20 mg of trenbolone acetate each. Injectable preparations containing 30 mg/ml of steroid in oil were formerly sold.

Structural Characteristics:

Trenbolone is a modified form of nandrolone. It differs by the introduction of double bonds at carbons 9 and 11, which inhibit aromatization (9-ene), increase androgen-binding affinity,[SUP]504[/SUP] and slow its metabolism. The resulting steroid is significantly more potent as both an anabolic and an androgen than its nandrolone base. Trenbolone acetate contains trenbolone modified with the addition of carboxylic acid ester (acetic acid) at the 17-beta hydroxyl group, so that the free steroid is released more slowly from the area of injection.
Side Effects (Estrogenic):

Trenbolone is not aromatized by the body, and is not measurably estrogenic. It is of note, however, that this steroid displays significant binding affinity for the progesterone receptor (slightly stronger than progesterone itself ).[SUP]505 506[/SUP] The side effects associated with progesterone are similar to those of estrogen, including negative feedback inhibition of testosterone production and enhanced rate of fat storage. Progestins also augment the stimulatory effect of estrogens on mammary tissue growth. There appears to be a strong synergy between these two hormones here, such that gynecomastia might even occur with the help of progestins, without excessive estrogen levels. The use of an anti-estrogen, which inhibits the estrogenic component of this disorder, is often sufficient to mitigate gynecomastia caused by progestational anabolic/androgenic steroids. Note that progestational side effects are more common when trenbolone is being taken with other aromatizable steroids.
Side Effects (Androgenic):

Although classified as an anabolic steroid, trenbolone is sufficiently androgenic. Androgenic side effects are still common with this substance, and may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are also warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Additionally, the 5-alpha reductase enzyme does not metabolize trenbolone,[SUP]507[/SUP] so its relative androgenicity is not affected by finasteride or dutasteride.
Side Effects (Hepatotoxicity):

Trenbolone is not c-17 alpha alkylated, and is generally not considered a hepatotoxic steroid; liver toxicity is unlikely. This steroid does have a strong level of resistance to hepatic breakdown, however, and significant liver toxicity has been noted in bodybuilders abusing trenbolone.[SUP]508[/SUP]Although unlikely, hepatotoxicity cannot be completely excluded, especially with high doses.
Side Effects (Cardiovascular):

Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Due to its non-aromatizable nature and strong resistance to metabolism, trenbolone has a moderate to strong (negative) impact on lipid values and atherogenic risk. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.
To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.
Side Effects (Testosterone Suppression):

All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention. In experimental studies, trenbolone was determined to be approximately three times stronger at suppressing gonadotropins than testosterone on a milligram for milligram basis.
The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects section of this book.
Administration (Men):

Trenbolone acetate was never approved for use in humans. Prescribing guidelines are unavailable. An effective dosage for physique- or performance-enhancing purposes generally falls in the range of 100-300 mg per week, taken for 6 to 8 weeks. Due to the short-acting nature of acetate esters, the total week’s dosage is subdivided into 2-3 smaller applications. Effective oral doses tend to fall in the range of 100-200 mg per day, taken for no longer than 6-8 weeks to minimize any potential hepatic strain. This level is sufficient to notice strong increases in strength and lean tissue mass, with a low level of unwanted side effects. Lack of estrogenic activity has made trenbolone very appealing for competitive athletes looking to shed fat, while at the same time trying to avoid water retention. Here, trenbolone may provide the high androgen content needed in order to elicit a very hard, defined physique.
While it is a noteworthy hardening agent, this is not the only benefit of trenbolone acetate. It is also a strong anabolic, with muscle-building properties often compared to testosterone and Dianabol, but without the same level of water retention. This may be a little generous of a description, as its lack of estrogenic activity does seem to hurt this agent in its abilities to promote muscle mass gains. While trenbolone is often recommended as a great addition to a mass cycle, it is rarely reported to be a very powerful agent when used alone. Results are most often reported as moderate lean tissue growth accompanied by exceptional hardening and fat loss. Although perhaps it is not quite as potent as the more estrogenic bulking agents if sheer mass is the goal, trenbolone is still a better builder milligram for milligram than nandrolone, and likely the most anabolic of all the non-estrogenic commercial steroids.
For stacking, trenbolone is a very versatile steroid, and seems to work exceptionally well with other agents for both bulking and cutting purposes. For cutting, bodybuilders often stack it with a mild anabolic like Winstrol® or Primobolan®. Without extra water beneath your skin, the mix will elicit a very solid, well-defined hardness to the physique. For lean mass gains, Deca-Durabolin® or Equipoise® are popular additions. Here again, trenbolone will greatly enhance and solidify the new muscle growth. When looking purely for mass, trenbolone pairs well with testosterone, Anadrol 50®, or Dianabol. The result is typically the rapid and substantial gain of somewhat solid muscle mass. In the Underground Steroid Hanbook II, Dan Duchaine describes the mix of trenbolone, testosterone, and Anadrol as the “Most Effective” stack for men, and states, “I’ve not encountered any other stack that will put weight and strength on like this one.” This particular drug combination has subsequently become quite popular.
Administration (Women):

Trenbolone acetate was never approved for use in humans. Prescribing guidelines are unavailable. This agent is not recommended for women for physique- or performance-enhancing purposes due to strong androgenic nature and tendency to produce virilizing side effects.
Availability:

Pharmaceutical preparations containing trenbolone acetate remain scarce. The bulk of the supply for this compound comes from underground steroid manufacturers.
Substance Identification:

Trenbolone (in oil) can be positively identified with ROIDTEST™ Substance Test D. This steroid produces an immediate deep purple response to this test, which is much faster than other AAS compounds. The trenbolone acetate ester is further differentiated with the use of Substance Test A. Following recent market trends, we find that black market preparations labeled as trenbolone acetate have a moderate to high risk of containing no or substitute steroid ingredients

​

[h=3]Description:[/h][FONT=&quot]Anavar is trade name for oxandrolone, an oral anabolic steroid derived from dihydrotestosterone. It was designed to have a very strong separation of anabolic and androgenic effect, and no significant estrogenic or progestational activity. Oxandrolone is noted for being quite mild as far as oral steroids are concerned, well tailored for the promotion of strength and quality muscle tissue gains without significant side effects. Milligram for milligram it displays as much as six times the anabolic activity of testosterone in assays, with significantly less androgenicity.[SUP]402[/SUP] This drug is a favorite of dieting bodybuilders and competitive athletes in speed/anaerobic performance sports, where its tendency for pure tissue gain (without fat or water retention) fits well with the desired goals.[/FONT]
[h=3]History:[/h][FONT=&quot]Oxandrolone was first described in 1962.[SUP]403[/SUP] It was developed into a medicine several years later by pharmaceutical giant G.D. Searle & Co. (now Pfizer), which sold it in the United States and the Netherlands under the Anavar trade name. Searle also sold/licensed the drug under different trade names including Lonavar (Argentina, Australia), Lipidex (Brazil), Antitriol (Spain), Anatrophill (France), and Protivar. Oxandrolone was designed to be an extremely mild oral anabolic, one that could even be used safely by women and children. In this regard Searle seems to have succeeded, as Anavar has shown a high degree of therapeutic success and tolerability in men, women, and children alike. During its early years, Anavar had been offered for a number of therapeutic applications, including the promotion of lean tissue growth during catabolic illness, the promotion of lean tissue growth following surgery, trauma, infection, or prolonged corticosteroid administration, or the support of bone density in patients with osteoporosis.[/FONT]
[FONT=&quot]By the 1980’s, the FDA had slightly refined the approved applications of Anavar to include the promotion of weight gain following surgery, chronic infection, trauma, or weight loss without definite pathophysiologic reason. In spite of its ongoing track record of safety, Searle decided to voluntarily discontinue the sale of Anavar on July 1, 1989. Lagging sales and growing public concern about the athletic use of anabolic steroids appeared to be at the root of this decision. With the Anavar brand off the market, oxandrolone had completely vanished from U.S. pharmacies. Soon after, oxandrolone products in international markets (often sold by or under license from Searle) began to disappear as well, as the leading global manufacturer of the drug continued its withdrawal from the anabolic steroid business. For several years during the early 1990’s, it looked as if Anavar might be on its way out of commerce for good.[/FONT]
[FONT=&quot]It would be approximately six years before oxandrolone tablets would be back on the U.S. market. The product returned to pharmacy shelves in December 1995, this time under the Oxandrin name by Bio-Technology General Corp. (BTG). BTG would continue selling it for the FDA approved uses involving lean mass preservation, but had also been granted orphan-drug status for the treatment of AIDS wasting, alcoholic hepatitis, Turner’s syndrome in girls, and constitutional delay of growth and puberty in boys. Orphan drug status gave BTG a 7-year monopoly on the drug for these new uses, allowing them to protect a very high selling price. Many patients were outraged to learn that the drug would cost them (at wholesale price) between $3.75 and $30 per day, which was many times more costly than Anavar had been just several years back. The release of a 10 mg tablet from BTG several years later did little to reduce the relative cost of the drug.[/FONT]
[FONT=&quot]Oxandrin® continues to be sold in the U.S., but is now under the Savient label (formerly known as BTG). It is currently approved by the FDA for “adjunctive therapy to promote weight gain after weight loss following extensive surgery, chronic infections, or severe trauma and in some patients who without definite pathophysiologic reasons fail to gain or to maintain normal weight, to offset the protein catabolism associated with prolonged administration of corticosteroids, and for the relief of the bone pain frequently accompanying osteoporosis.” Generic versions of the drug are now available in the U.S., which has reduced the price of oxandrolone therapy. Outside of the U.S., oxandrolone remains available, although not widely.[/FONT]
[h=3]How Supplied:[/h][FONT=&quot]Oxandrolone is available in select human drug markets. Composition and dosage may vary by country and manufacturer. The original Anavar brand contained 2.5 mg of steroid per tablet. Oxandrin contains 2.5 mg or 10 mg per tablet. Other modern brands commonly contain 2.5 mg, 5 mg, or 10 mg of steroid per tablet.[/FONT]
[h=3]

[/h][h=3]Structural Characteristics:[/h][FONT=&quot]Oxandrolone is a modified form of dihydrotestosterone. It differs by: 1) the addition of a methyl group at carbon 17-alpha to protect the hormone during oral administration and 2) the substitution of carbon-2 in the A-ring with an oxygen atom. Oxandrolone is the only commercially available steroid with such a substitution to its basic ring structure, an alteration that considerably increases the anabolic strength of the steroid (partly by making it resistant to metabolism by 3-hydroxysteroid dehydrogenase in skeletal muscle tissue).[/FONT]
[h=3]Side Effects (Estrogenic):[/h][FONT=&quot]Oxandrolone is not aromatized by the body, and is not measurably estrogenic. Oxandrolone also offers no related progestational activity.[SUP]404[/SUP] An anti-estrogen is not necessary when using this steroid, as gynecomastia should not be a concern even among sensitive individuals. Since estrogen is the usual culprit with water retention, oxandrolone instead produces a lean, quality look to the physique with no fear of excess subcutaneous fluid retention. This makes it a favorable steroid to use during cutting cycles, when water and fat retention are major concerns. Oxandrolone is also very popular among athletes in strength/speed sports such as sprinting, swimming, and gymnastics. In such disciplines one usually does not want to carry around excess water weight, and may find the raw muscle-growth brought about by oxandrolone to be quite favorable over the lower quality mass gains of aromatizable agents.[/FONT]
[h=3]Side Effects (Androgenic):[/h][FONT=&quot]Although classified as an anabolic steroid, androgenic side effects are still possible with this substance. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Oxandrolone is a steroid with low androgenic activity relative to its tissue-building actions, making the threshold for strong androgenic side effects comparably higher than with more androgenic agents such as testosterone, methandrostenolone, or fluoxymesterone.[/FONT]
[FONT=&quot]The low androgenic activity of oxandrolone is due in part to it being a derivative of dihydrotestosterone. This creates a less androgenic steroid because the agent lacks the capacity to interact with the 5-alpha reductase enzyme and convert to a more potent “di-hydro”form. This is unlike testosterone, which is several times more active in androgen responsive target tissues such as the scalp, skin, and prostate (where 5-alpha reductase is present in high amounts) due to its conversion to DHT. In essence, oxandrolone has a more balanced level of potency between muscle and androgenic target tissues. This is a similar situation as is noted with Primobolan and Winstrol, which are also derived from dihydrotestosterone and not known to be very androgenic substances.[/FONT]
[h=3]Side Effects (Hepatotoxicity):[/h][FONT=&quot]Oxandrolone is a c17-alpha alkylated compound. This alteration protects the drug from deactivation by the liver, allowing a very high percentage of the drug entry into the bloodstream following oral administration. C17-alpha alkylated anabolic/androgenic steroids can be hepatotoxic. Prolonged or high exposure may result in liver damage. In rare instances life-threatening dysfunction may develop. It is advisable to visit a physician periodically during each cycle to monitor liver function and overall health. Intake of c17-alpha alkylated steroids is commonly limited to 6-8 weeks, in an effort to avoid escalating liver strain.[/FONT]
[FONT=&quot]Oxandrolone appears to offer less hepatic stress than other c-17 alpha alkylated steroids. The manufacturer identifies oxandrolone as a steroid that is not extensively metabolized by the liver like other 17-alpha alkylated orals, which may be a factor in its reduced hepatotoxicity. This is evidenced by the fact that more than a third of the compound is still intact when excreted in the urine.[SUP]405[/SUP] Another study comparing the effects of oxandrolone to other alkylated agents including methyltestosterone, norethandrolone, fluoxymesterone, and methandriol demonstrated that oxandrolone causes the lowest sulfobromophthalein (BSP; a marker of liver stress) retention of the agents tested.[SUP]406[/SUP] 20 mg of oxandrolone produced 72% less BSP retention than an equal dosage of fluoxymesterone,which is a considerable difference being that they are both 17-alpha alkylated.[/FONT]
[FONT=&quot]A more recent study looked at escalating doses (20 mg, 40 mg, and 80 mg) of oxandrolone in 262 HIV+ men.The drug was administered for a period of 12 weeks. The group taking 20 mg of oxandrolone per day showed no statistically significant trends of hepatotoxicity in liver enzyme (AST/ALT; amino-transferase and alanine amino-transferase) values. Those men taking 40 mg noticed a mean increase of approximately 30-50% in liver enzyme values, while the group of men taking 80 mg noticed an approximate 50-100% increase. Approximately 10-11% of the patients in the 40 mg group noticed World Health Organization grade III and IV toxicity according to AST and ALT values. This figure jumped to 15% in the 80 mg group. While serious hepatotoxicity cannot be excluded with oxandrolone, these studies do suggest that it is measurably safer than other alkylated agents.[/FONT]
[FONT=&quot]The use of a liver detoxification supplement such as Liver Stabil, Liv-52, or Essentiale Forte is advised while taking any hepatotoxic anabolic/androgenic steroids.[/FONT]
[h=3]Side Effects (Cardiovascular):[/h][FONT=&quot]Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Oxandrolone has a strong effect on the hepatic management of cholesterol due to its structural resistance to liver breakdown, non-aromatizable nature, and route of administration. In the previously cited study in HIV+ males, 20 mg of oxandrolone daily for 12 weeks caused a mean serum HDL reduction of 30%. HDL values were suppressed 33% in the 40 mg group, and 50% in the 80 mg group. This was accompanied by a statistically significant increase in LDL values (approximately 30-33%) in the 40 mg and 80 mg groups, further increasing atherogenic risk. Anabolic/androgenic steroids may also adversely effect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.[/FONT]
[FONT=&quot]At one time oxandrolone was looked at as a possible drug for those suffering from disorders of high cholesterol or triglycerides. Early studies showed it to be capable of lowering total cholesterol and triglyceride values in certain types of hyperlipidemic patients, which was thought to signify potential for this drug as a lipid-lowering agent.[SUP]407[/SUP] With further investigation it was found, however, that any lowering of total cholesterol values was accompanied by a redistribution in the ratio of good (HDL) to bad (LDL) cholesterol that favored greater atherogenic risk.[SUP]408 409[/SUP] This negates any positive effect this drug might have on triglycerides or total cholesterol, and actually makes it a potential danger in terms of cardiac risk, especially when taken for prolonged periods of time. Today we understand that as a group, anabolic/androgenic steroids tend to produce unfavorable changes in lipid profiles, and are really not useful in disorders of lipid metabolism. As an oral c17 alpha alkylated steroid, oxandrolone is even more risky to use in this regard than an esterified injectable such as a testosterone or nandrolone.[/FONT]
[FONT=&quot]To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.[/FONT]
[h=3]Side Effects (Testosterone Suppression):[/h][FONT=&quot]All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Oxandrolone is no exception. In the above-cited study on HIV+ males, twelve weeks of 20 mg or 40 mg per day caused an approximate 45% reduction in serum testosterone levels. The group taking 80 mg noticed a 66% decrease in testosterone. Similar trends of decrease were noticed in LH production, with the 20 mg and 40 mg doses causing a 25-30% reduction, and the 80 mg group noticing a decline of more than 50%. Additionally, studies on boys with constitutionally delayed puberty have demonstrated significant suppression of endogenous LH and testosterone with as little as 2.5 mg per day.[SUP]410[/SUP]Without the intervention of testosterone stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.[/FONT]
[FONT=&quot]The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects section of this book.[/FONT]
[h=3]Administration (General):[/h][FONT=&quot]Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability.[SUP]411[/SUP] This is caused by the fat-soluble nature of steroid hormones, which can allow some of the drug to dissolve with undigested dietary fat, reducing its absorption from the gastrointestinal tract. For maximum utilization, this steroid should be taken on an empty stomach.[/FONT]
[h=3]Administration (Men):[/h][FONT=&quot]The original prescribing guidelines for Anavar called for a daily dosage of between 2.5 mg and 20 mg per day (5-10 mg being most common). This was usually recommended for a period of two to four weeks, but occasionally it was taken for as long as three months. The dosing guidelines recommended with the current U.S. production form of the drug (Oxandrin, Savient Pharmaceuticals) also call for between 2.5 and 20 mg of drug per day, taken in intermittent cycles of 2 to 4 weeks. The usual dosage for physique- or performance-enhancing purposes is in the range of 15-25 mg per day, taken for 6 to 8 weeks. These protocols are not far removed from those of normal therapeutic situations.[/FONT]
[FONT=&quot]Oxandrolone is often combined with other steroids for a more dramatic result. For example, while bulking one might opt to add in 200-400 mg of a testosterone ester (cypionate, enanthate, or propionate) per week. The result should be a considerable gain in new muscle mass, with a more comfortable level of water and fat retention than if taking a higher dose of testosterone alone. For dieting phases, one might alternately combine oxandrolone with a non-aromatizing steroid such as 150 mg per week of a trenbolone ester or 200-300 mg of Primobolan® (methenolone enanthate). Such stacks are highly favored for increasing definition and muscularity. An in-between (lean mass gain) might be to add in 200-400 mg of a low estrogenic compound like Deca-Durabolin® (nandrolone decanoate) or Equipoise® (boldenone undecylenate).[/FONT]
[h=3]Administration (Women):[/h][FONT=&quot]The original prescribing guidelines for Anavar did not offer separate dosing recommendations for women, although it was indicated that women who were pregnant, or may become pregnant, should not use the drug. The current guidelines for Oxandrin also do not make special dosing recommendations for women. Women who fear the masculinizing effects of many steroids would be quite comfortable using this drug, as these properties are very rarely seen with low doses. For physique- or performance-enhancing purposes, a daily dosage of 5-10 mg should illicit considerable growth without the noticeable androgenic side effects of other drugs. This would be taken for no longer than 4-6 weeks. Eager females may wish to add another mild anabolic such as Winstrol®, Primobolan® or Durabolin®. When combined with such anabolics, the user should notice faster, more pronounced muscle-building effects, but it may also increase the likelihood of seeing androgenic side effects (or hepatotoxicity in the case of Winstrol).[/FONT]
[h=3]Availability:[/h][FONT=&quot]Generic forms of oxandrolone are available in the United States in both 2.5 mg and 10 mg dosages. Outside of the U.S., however, pharmaceutical preparations containing oxandrolone are fairly limited. The drug is unavailable in Europe, and with a handful of exceptions in the west. In recent years, production has increasingly shifted to less regulated markets in Asia.[/FONT]

​

[h=3]Description:[/h][FONT=&quot]Dianabol is the most recognized trade name for the drug methandrostenolone, also referred to as methandienone in many countries. Methandrostenolone is a derivative of testosterone, modified so that the hormone’s androgenic (masculinizing) properties are reduced and its anabolic (tissue building) properties preserved. Having a lower level of relative androgenicity than testosterone, methandrostenolone is classified as an “anabolic” steroid, although quite a distinct androgenic side is still present. This drug was designed, and is principally sold, as an oral medication, although it can also be found in a number of injectable veterinary solutions. Dianabol is today, and has historically been, the most commonly used oral anabolic/androgenic steroid for physique and performance-enhancing purposes.
[h=3]History:[/h][FONT=&quot]Methandrostenolone was first described in 1955.[SUP]460[/SUP] It was released to the U.S. prescription drug market in 1958, under the brand name Dianabol by Ciba Pharmaceuticals. Ciba developed methandrostenolone into a medicine with the help of Dr. John Ziegler, who was the team physician for a number of U.S. Olympic teams, including weightlifting. Ziegler makes note in Bob Goldman’s Death in the Locker Room that he was first exposed to steroids at the 1956 World Games, seeing that the Russians were heavily abusing testosterone on their strength athletes. According to Ziegler, the hormone was having noticeable side effects, and one athlete had such profound prostate enlargement that he was forced to urinate with the aid of a catheter. While working with Ciba, the company tested a steroid (synthesized earlier) that had reduced androgenicity compared to testosterone, but with retained tissue-building (anabolic) properties. This had been accomplished by altering the basic chemical structure of testosterone in a way that altered its metabolism and disposition in the body. With the help of Dr. Ziegler, Ciba brought to market one of the most effective oral “anabolic” steroid medicines ever known, methandrostenolone. The success of the drug was rapid and far-reaching.[/FONT]
[FONT=&quot]Dr. Ziegler’s athletes were quickly making great advancements in their competitive careers with the help of the drug. According to reports, Ziegler too seemed to be very impressed, at least for a while.[SUP]461[/SUP] But by the early 1960’s, it was starting to look like Dianabol had sparked a great wave of steroid abuse in competitive sports. Dr. Ziegler’s early recommendations, which depending on the source called for as little as 5 mg per day or as much as 15 mg per day, were being largely ignored, as athletes developed their own more aggressive (and potentially dangerous) dosing strategies. Dr. Ziegler soon became disgusted with the misuse of the drug, and would eventually become a voice of opposition to sports doping. By 1967, approximately 10 years after first introducing Dianabol to his athletes, he had categorically condemned the use of anabolic steroids in sports.[SUP]462[/SUP][/FONT]
[FONT=&quot]As early as 1965, Dianabol was already starting to fall under scrutiny of the U.S. Food and Drug Administration. That year the FDA requested Ciba clarify Dianabol’s medical uses,which were then stated to include helping patients in debilitated states and those with weakened bones. In 1970, the FDA accepted that Dianabol was “Probably Effective” in treating post-menopausal osteoporosis and pituitary-deficient dwarfism. These changes were reflected in the drug’s prescribing recommendations during the 1970’s, and Ciba was allowed to continue selling and studying the agent. Ciba eventually lost patent protection, however, and companies like Parr, Barr, Bolar, and Rugby were soon cutting deeply into their market with their own generic version of the drug.[/FONT]
[FONT=&quot]By the early-80’s the FDA had withdrawn its “Probably Effective” position on the pituitary-deficient dwarfism, and continued to press Ciba for more data. Sufficient clarification never came, and in 1983 Ciba officially withdrew Dianabol from the U.S. market.[SUP]463[/SUP] Perhaps financial disinterest had a hand in their abandoned push to keep the drug approved. The FDA pulled all generic forms of methandrostenolone from the U.S. market in 1985, a time when most Western nations were also eliminating the drug, finding its existence to be justified mainly by sports doping. Methandrostenolone is still produced today, but typically in nations with loose prescription drug regulations, and by companies that still prefer to cater to an underground athletic market.[/FONT]
[h=3]How Supplied:[/h][FONT=&quot]Methandrostenolone is widely available in both human and veterinary drug markets. Composition and dosage may vary by country and manufacturer. Methandrostenolone was designed as an oral anabolic steroid containing 2.5 mg or 5 mg of steroid per tablet (Dianabol). Modern brands usually contain 5 mg or 10 mg per tablet. Methandrostenolone can also be found in injectable veterinary preparations. These are typically oilbased solutions that carry 25 mg/ml of steroid.[/FONT]
[h=3]

[/h][h=3]Structural Characteristics:[/h][FONT=&quot]Methandrostenolone is a modified form of testosterone. It differs by: 1) the addition of a methyl group at carbon 17- alpha to protect the hormone during oral administration and 2) the introduction of a double bond between carbons 1 and 2, which reduces its relative androgenicity. The resulting steroid also has a much weaker relative binding affinity for the androgen receptor than testosterone, but at the same time displays a much longer half-life and lower affinity for serum-binding proteins in comparison. These features (among others) allow methandrostenolone to be a very potent anabolic steroid in spite of a weaker affinity for receptor binding. Recent studies have additionally confirmed that its primary mode of action involves interaction with the cellular androgen receptor.[SUP]464[/SUP][/FONT]
[h=3]Side Effects (Estrogenic):[/h][FONT=&quot]Methandrostenolone is aromatized by the body, and is a moderately estrogenic steroid.[SUP]465[/SUP]Gynecomastia is often a concern during treatment, and may present itself quite early into a cycle (particularly when higher doses are used). At the same time water retention can become a problem, causing a notable loss of muscle definition as both subcutaneous water retention and fat levels build. Sensitive individuals may therefore want to keep the estrogen under control with the addition of an anti-estrogen such as Nolvadex® and/or Proviron®. One may alternately use an aromatase inhibitor like Arimidex® (anastrozole), which is a more effective remedy for estrogen control. Aromatase inhibitors, however, can be quite expensive in comparison to standard estrogen maintenance therapies, and may also have negative effects on blood lipids.[/FONT]
[FONT=&quot]It is interesting to note that methandrostenolone is structurally identical to boldenone, except that it contains the added c17-alpha-methyl group. This fact makes clear the impact of altering a steroid in such a way, as these two compounds appear to act very differently in the body. A key dissimilarity seems to lie in the tendency for estrogenic side effects. Equipoise® (boldenone undecylenate) is known to be quite mild in this regard, and users commonly take this drug without the need to add an anti-estrogen. Methandrostenolone is much more estrogenic, often necessitating anti-estrogen use. But this difference is not caused by methandrostenolone being more easily aromatized. In fact, the 17-alpha methyl group and c1-2 double bond both slow the process of aromatization considerably. The issue actually is caused by methandrostenolone converting to 17alpha-methylestradiol, a more biologically active form of estrogen than estradiol.[/FONT]
[h=3]Side Effects (Androgenic):[/h][FONT=&quot]Although classified as an anabolic steroid, androgenic side effects are still common with this substance. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Individuals sensitive to the androgenic effects of methandrostenolone may find a milder anabolic such as Deca-Durabolin® to be more comfortable. Women are additionally warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement.[/FONT]
[FONT=&quot]While methandrostenolone does convert to a more potent steroid via interaction with the 5-alpha reductase enzyme (the same enzyme responsible for converting testosterone to dihydrotestosterone), it has an extremely low affinity to do so.[SUP]466[/SUP] The androgenic metabolite 5-alpha dihydromethandrostenolone is produced only in trace amounts, so the relative androgenicity of methandrostenolone is not significantly affected by finasteride or dutasteride.[/FONT]
[h=3]Side Effects (Hepatotoxicity):[/h][FONT=&quot]Methandrostenolone is a c17-alpha alkylated compound. This alteration protects the drug from deactivation by the liver, allowing a very high percentage of the drug entry into the bloodstream following oral administration. C17-alpha alkylated anabolic/androgenic steroids can be hepatotoxic. Prolonged or high exposure may result in liver damage. In rare instances life-threatening dysfunction may develop. It is advisable to visit a physician periodically during each cycle to monitor liver function and overall health. Intake of c17-alpha alkylated steroids is commonly limited to 6-8 weeks, in an effort to avoid escalating liver strain.[/FONT]
[FONT=&quot]Studies have shown that several weeks of methandrostenolone administration offers minimal hepatic stress so long as it is given at a dosage of 10 mg per day or below. At a dose of 15 mg per day, a majority of patients will begin to demonstrate disturbed liver function as measured by clinically elevated bromosulphalein retention (a marker of hepatic stress).[SUP]467[/SUP] Even at 2.5 and 5 mg per day, elevations in BSP retention have been reported in patients. Severe liver complications are rare given the periodic nature in which most people use oral anabolic/androgenic steroids, although cannot be excluded with methandrostenolone, especially with high doses and/or prolonged administration periods.[/FONT]
[FONT=&quot]The use of a liver detoxification supplement such as Liver Stabil, Liv-52, or Essentiale Forte is advised while taking any hepatotoxic anabolic/androgenic steroids.[/FONT]
[h=3]Side Effects (Cardiovascular):[/h][FONT=&quot]Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Methandrostenolone has a strong effect on the hepatic management of cholesterol due to its structural resistance to liver breakdown and route of administration. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.[/FONT]
[FONT=&quot]To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.[/FONT]
[h=3]Side Effects (Testosterone Suppression):[/h][FONT=&quot]All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Methandrostenolone is no exception, and is noted for its strong influence on the hypothalamic-pituitary-testicular axis. Clinical studies giving 15 mg per day to resistance-training males for 8 weeks caused the mean plasma testosterone level to fall by 69%.[SUP]468[/SUP] Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.[/FONT]
[FONT=&quot]The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects section of this book.[/FONT]
[h=3]Administration (General):[/h][FONT=&quot]Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability.[SUP]469[/SUP] This is caused by the fat-soluble nature of steroid hormones, which can allow some of the drug to dissolve with undigested dietary fat, reducing its absorption from the gastrointestinal tract. For maximum utilization, this steroid should be taken on an empty stomach.[/FONT]
[h=3]Administration (Men):[/h][FONT=&quot]The original prescribing guidelines for Dianabol called for a daily dosage of 5 mg. This was to be administered on an intermittent basis, with the drug taken for no more than 6 consecutive weeks. Thereafter, a break of 2 to 4 weeks was advised before therapy was resumed. For physique- or performance-enhancing purposes, the drug is also used intermittently, with cycles usually lasting between 6 and 8 weeks in length followed by 6-8 weeks off. Although a low dose of 5 mg daily may be effective for improving performance, athletes typically take much higher amounts. A daily dosage of three to six 5 mg tablets (15-30 mg) is most common, and typically produces very dramatic results. Some venture even higher in dosage, but this practice usually leads to a more profound incidence of side effects, and is generally discouraged.[/FONT]
[FONT=&quot]Dianabol stacks well with a variety of other steroids. It is noted to mix particularly well with the mild anabolic Deca-Durabolin®, for example. Together one can expect exceptional muscle and strength gains, with side effects not much worse than one would expect from Dianabol alone. For sheer mass, a long-acting testosterone ester like enanthate or cypionate can be used. With the high estrogenic/androgenic properties of this androgen, however, side effects should be more pronounced. Gains would be pronounced as well, which usually makes such an endeavor worthwhile to the user. As discussed earlier, ancillary drugs can be added to reduce the side effects associated with this kind of cycle.[/FONT]
[FONT=&quot]The half-life of Dianabol is only about 3 to 5 hours. A single daily dosage schedule will produce a varying blood level, with ups and downs throughout the day. The user, likewise, has a choice, to either split up the tablets during the day or to take them all at one time. The usual recommendation has been to divide them and try to regulate the concentration in your blood. This, however, will produce a lower peak blood level than if the tablets were taken all at once, so there may be a trade-off with this option. Both options work fine, but anecdotal evidence seems to support single daily doses as being better for overall results. With such a schedule, it seems logical that taking the pills earlier in the day would be optimal. This would allow a considerable number of daytime hours for an androgen-rich metabolism to heighten the uptake of nutrients, especially the critical hours following training.[/FONT]
[h=3]Administration (Women):[/h][FONT=&quot]Being moderately androgenic, Dianabol is really only a popular steroid with men. When used by women, strong virilization symptoms are possible. Some do experiment with it, however, and often find low doses (2.5-5 mg) of this steroid quite effective for new muscle growth. Studies have demonstrated that a majority of women will notice acne, which is indicative of androgenicity, at a dosage of only 10 mg per day. Children are likely to notice virilizing effects with as little as 2.5 mg per day.[/FONT]

[h=3]Description:[/h][FONT=&quot]Equipoise is the most commonly recognized trade name for boldenone undecylenate, an injectable veterinary steroid that exhibits strong anabolic and moderately androgenic properties. The undecylenate ester extends the activity of the drug greatly (the undecylenate ester is only one carbon atom longer than decanoate), so that injections need to be repeated only once every 3 or 4 weeks. The well-balanced anabolic and androgenic properties of this drug are greatly appreciated by athletes, who generally consider it to be a stronger, slightly more androgenic, alternative to Deca-Durabolin®. It is generally cheaper, and could replace Deca in most cycles without greatly changing the end result. Boldenone undecylenate is also commonly known as a drug capable of increasing red blood cell production, although there should be no confusion that this is an effect characteristic of nearly all anabolic/androgenic steroids.[/FONT]
[h=3]History:[/h][FONT=&quot]Ciba reportedly patented boldenone as a synthetic anabolic steroid in 1949. During the 1950’s and ’60’s, the firm developed several experimental esters of the drug, and would later release a long-acting form of the agent (briefly) in the form of boldenone undecylenate. It would be sold under the brand name Parenabol, which likely referred to its characteristics as a parenteral (injectable) anabolic agent. Parenabol saw some clinical use during the late ’60’s and early ’70’s, mainly as a lean-tissue-preserving anabolic agent in cases of wasting, and for the retention of bone mass with osteoporosis. Boldenone undecylenate was a short-lived preparation on human medical markets, however, and would be discontinued globally before the end of the 1970’s. Squibb would ultimately be most famous for introducing this agent in the veterinary market, and would sell it under its now most famous trade name, Equipoise.[/FONT]
[FONT=&quot]In the veterinary market, boldenone undecylenate is most commonly applied to horses, although in many regions it is indicated for use in other animals as well. It generally exhibits a pronounced effect on lean bodyweight, appetite, and general disposition of the animal. The Equipoise brand was sold under the Squibb label until 1985, when Solvay acquired Squibb’s U.S. animal health business. Equipoise would be sold under the Solvay label for the next several years, until Wyeth finally acquired the animal health division of Solvay in 1995. The division was formed into Fort Dodge Animal Health, which continues to market Equipoise in the U.S. and certain markets abroad today. Many other generic and brand name forms of boldenone undecylenate exist in numerous international drug markets, owing to the fact that any patents on boldenone undecylenate have long since expired.[/FONT]
[h=3]How Supplied:[/h][FONT=&quot]Boldenone undecylenate is widely available in veterinary drug markets. Composition and dosage may vary by country and manufacturer; the majority of products are supplied as multi-dose glass vials containing an oily solution; usually carrying 25 mg/ml or 50 mg/ml of steroid.[/FONT]
[h=3]

[/h][h=3]Structural Characteristics:[/h][FONT=&quot]Boldenone is a modified form of testosterone. It differs by the introduction of a double bond between carbons 1 and 2, which reduces its relative estrogenicity and androgenicity. Equipoise® contains boldenone modified with the addition of carboxylic acid ester (undecylenoic acid) at the 17-beta hydroxyl group. Esterified steroids are less polar than free steroids, and are absorbed more slowly from the area of injection. Once in the bloodstream, the ester is removed to yield free (active) boldenone. Esterified steroids are designed to prolong the window of therapeutic effect following administration, allowing for a less frequent injection schedule compared to injections of free (unesterified) steroid. Boldenone undecylenate is designed to provide a peak release of boldenone within a few days after injection, and sustain hormone release for approximately 21-28 days.[/FONT]
[FONT=&quot]It is interesting to note that structurally boldenone and methandrostenolone (Dianabol) are almost identical. In the case of boldenone (as applied here), the compound uses a 17-beta ester (undecylenate) to facilitate administration, while methandrostenolone accomplishes this with the use of a 17-alpha alkyl group. Aside from this, the molecules are the same. Of course they act quite differently in the body, which goes to show that the 17-methylation affects more than just the oral efficacy of an anabolic/androgenic steroid.[/FONT]
[h=3]Side Effects (Estrogenic):[/h][FONT=&quot]Boldenone is aromatized in the body to estradiol (estrogen). Elevated estrogen levels can cause side effects such as increased water retention, body fat gain, and gynecomastia. Boldenone is considered a mildly estrogenic steroid. Aromatization studies suggest that its rate of conversion to estradiol is roughly half that of testosterone.[SUP]501[/SUP] The tendency to develop noticeable estrogenic side effects with boldenone should be slightly higher than nandrolone, but much lower than with testosterone. Estrogenic side effects are usually not pronounced unless this drug is taken in doses above 200-400 mg per week. An anti-estrogen such as clomiphene citrate or tamoxifen citrate might be used to help mitigate these side effects, should they become present. One may alternately use an aromatase inhibitor like Arimidex® (anastrozole), although it is considerably more expensive, and may negatively affect blood lipids.[/FONT]
[h=3]Side Effects (Androgenic):[/h][FONT=&quot]Although classified as an anabolic steroid, androgenic side effects are still common with this substance, especially with higher doses. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are also warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement.[/FONT]
[FONT=&quot]Note that while boldenone does reduce to a more potent androgen (dihydroboldenone) via the 5-alpha reductase enzyme in androgen-responsive target tissues such as the skin, scalp, and prostate, its affinity to do so in the human body is extremely low.[SUP]502[/SUP] The relative androgenicity of boldenone is, therefore, not significantly affected by finasteride or dutasteride.[/FONT]
[h=3]Side Effects (Hepatotoxicity):[/h][FONT=&quot]Boldenone is not c-17 alpha alkylated, and not known to have hepatotoxic effects. Liver toxicity is unlikely.[/FONT]
[h=3]Side Effects (Cardiovascular):[/h][FONT=&quot]Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction. Boldenone is likely to have a less dramatic impact on cardiovascular risk factors than synthetic oral anabolic steroids. This is due in part to its openness to metabolism by the liver, which allows it to have less effect on the hepatic management of cholesterol. The aromatization of boldenone to estradiol may also help to mitigate the negative effects of androgens on serum lipids.[/FONT]
[FONT=&quot]To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.[/FONT]
[h=3]Side Effects (Testosterone Suppression):[/h][FONT=&quot]All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.[/FONT]
[FONT=&quot]The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects section.[/FONT]
[h=3]Administration (Men):[/h][FONT=&quot]Although it stays active for a much longer time, boldenone undecylenate is injected at least weekly for physique- or performance-enhancing purposes. It is most commonly used at a dosage of 200-400 mg (4-8ml,50 mg version) per week. The dosage schedule can be further divided to reduce the volume of each injection if necessary, perhaps administering the drug two to three times per week. One should also take caution to rotate injection sites regularly, so as to avoid irritation or infection.[/FONT]
[FONT=&quot]Not a rapid mass builder, boldenone undecylenate instead provides a slow but steady gain of strength and quality muscle mass. The positive effects of this drug become most apparent when it is used for longer cycles, usually lasting 8 weeks or more in duration. The muscle gained should also not be the smooth bulk associated with testosterone, but more defined and solid. Since water bloat is not contributing greatly to the diameter of the muscle, more of the visible size gained on a cycle of boldenone undecylenate should be retained after the drug has been discontinued.[/FONT]
[FONT=&quot]Boldenone undecylenate is a very versatile drug, and can be combined with a number of other agents depending on the desired result. For mass, it is commonly stacked with an injectable testosterone such as enanthate or cypionate. This should produce strong gains in muscle size and strength, without the same intensity of side effects of using testosterone (at a higher dose) alone. During a cutting phase, muscle hardness and density can be greatly improved when combining boldenone undecylenate with a non-aromatizable steroid such as trenbolone acetate or methenolone enanthate. Oral c-17 alpha alkylated agents such as fluoxymesterone or stanozolol may also be used, but will present some level of hepatotoxicity. For some, even the low buildup of estrogen associated with this compound is enough to relegate its use to bulking cycles only.[/FONT]
[h=3]Administration (Women):[/h][FONT=&quot]When used for physique- or performance-enhancing purposes, women take much lower doses of boldenone undecylenate than men, typically 50-75 mg per week. Women should take caution with the slow-acting characteristics of this preparation, which make blood levels difficult to control and slow to decline should virilization symptoms become present.[/FONT]
[h=3]Availability:[/h][FONT=&quot]Boldenone undecylenate remains widely available as a veterinary drug product. It is produced mainly in the Americas, consistently at a dosage of 25 mg/mL or 50 mg/mL. A small number of preparations are made at a higher dosage (typically 200 mg/mL), mainly by companies in less regulated markets of Asia where supply is often dictated by black market demand.[/FONT]

Description:
Masteron, the most recognized trade name for drostanolone propionate, is an injectable anabolic steroid derived from dihydrotestosterone (DHT). Here, the DHT backbone has been modified with a 2-methyl group to increase its anabolic properties, making this agent significantly more effective at promoting the growth of muscle tissue than its non-methylated parent. Drostanolone propionate is described in product literature as a “steroid with powerful anabolic and anti-estrogenic properties,” and indeed does seem to share some of both properties. Admittedly, however, its anabolic properties are more properly described as moderate, especially when placed in the context of other agents. The drug is most often used by dieting bodybuilders and athletes in speed sports, where it is highly favored for its ability to produce solid increases in lean muscle mass and strength, which are usually accompanied by reductions in body fat level and minimal side effects.

History:
Drostanolone propionate was first described in 1959.526 Syntex developed the agent alongside such other well-known steroids as Anadrol and methyldrostanolone (Superdrol), also first described in the same paper. Drostanolone propionate would be introduced as a prescription drug product approximately a decade later. Lilly had an agreement with Syntex to split certain research and development costs in exchange for the rights to market the results of that research. Lilly would, therefore, sell drostanolone propionate in the U.S. under the Drolban brand name, while Syntex would sell/license it in other markets. Products included Masteron in Belgium (Sarva-Syntex) and Portugal (Cilag), Masteril in the U.K. and Bulgaria, and Metormon in Spain. Drostanolone propionate was also found in such popular preparations as Permastril (Cassenne, France), Mastisol (Shionogi, Japan), and Masterid (Grunenthal, Germany Democratic Republic).

The U.S. Food and Drug Administration approved drostanolone propionate for the treatment of advanced inoperable breast cancer in postmenopausal women. This remained the principle clinical indication for the agent in all international markets as well. The prescribing literature reminds doctors and female patients that there is considerably less virilization with drostanolone propionate as compared to equal doses of testosterone propionate, suggesting this was a much more comfortable alternative to testosterone injections for the given audience. Still, the given dosage level (300 mg per week) was relatively high, and the literature also reminds us that mild virilization symptoms still commonly occur, such as deepening of the voice, acne, facial hair growth, and enlargement of the clitoris. It also reports that marked virilization sometimes follows long-term therapy.

While highly popular among athletes during the 1970’s and ’80’s, drostanolone propionate ultimately enjoyed limited success as a prescription agent. Manufacturers began voluntarily discontinuing sale of the agent in various markets before long, likely due to the advent of more effective therapies for breast cancer, as well as the slow decline in steroid prescriptions for this phase of treatment. One of the first preparations to go was the U.S. Drolban, which was removed from market during the late 1980’s. Permastril and Metormon were soon dropped as well. The last remaining Western preparation containing drostanolone propionate was Masteron from Belgium, which disappeared by the late 1990’s. Drostanolone propionate remains listed on the U.S. Pharmacopias, suggesting there is presently no legal roadblock to its sale, although its reemergence as a prescription drug product seems highly unlikely.

How Supplied:
Masteron is no longer available as a prescription drug preparation. When produced, it was supplied in the form of 1 mL and 2 mL ampules and 10 mL vials containing 50 mg/ml or 100 mg/ml of steroid in oil.

masteron drostanolone structure molecule
Structural Characteristics:
Drostanolone (also known as dromostanolone) is a modified form of dihydrotestosterone. It differs by the introduction of a methyl group at carbon-2 (alpha), which considerably increases the anabolic strength of the steroid by heightening its resistance to metabolism by the 3-hydroxysteroid dehydrogenase enzyme in skeletal muscle tissue. Drostanolone propionate is a modified form of drostanolone, where a carboxylic acid ester (propionic acid) has been attached to the 17-beta hydroxyl group. Esterified steroids are less polar than free steroids, and are absorbed more slowly from the area of injection. Once in the bloodstream, the ester is removed to yield free (active) drostanolone. Esterified steroids are designed to prolong the window of therapeutic effect following administration, allowing for a less frequent injection schedule compared to injections of free (unesterified) steroid. The half-life of drostanolone propionate is approximately two days after injection.

Side Effects (Estrogenic):
Drostanolone is not aromatized by the body, and is not measurably estrogenic. An anti-estrogen is not necessary when using this steroid, as gynecomastia should not be a concern even among sensitive individuals. Since estrogen is the usual culprit with water retention, drostanolone instead produces a lean, quality look to the physique with no fear of excess subcutaneous fluid retention.This makes it a favorable steroid to use during cutting cycles, when water and fat retention are major concerns. As a non-aromatizable DHT derivative, drostanolone may impart an anti-estrogenic effect, the drug competing with other (aromatizable) substrates for binding to the aromatase enzyme.

Side Effects (Androgenic):
Although classified as an anabolic steroid, androgenic side effects are still possible with this substance, especially with higher than normal therapeutic doses. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement.

Drostanolone is a steroid with relatively low androgenic activity relative to its tissue-building actions, making the threshold for strong androgenic side effects comparably higher than with more androgenic agents such as testosterone, methandrostenolone, or fluoxymesterone. Note that drostanolone is unaffected by the 5-alpha reductase enzyme, so its relative androgenicity is not affected by the concurrent use of finasteride or dutasteride.

Side Effects (Hepatotoxicity):
Masteron is not c17-alpha alkylated, and not known to have hepatotoxic properties. Liver toxicity is unlikely.

Side Effects (Cardiovascular):
Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Drostanolone should have a stronger negative effect on the hepatic management of cholesterol than testosterone or nandrolone due to its non-aromatizable nature, but a weaker impact than c-17 alpha alkylated steroids. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.

To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.

Side Effects (Testosterone Suppression):
All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.

The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects section of this book.

Administration (Men):
Drostanolone propionate was not FDA approved for use in men. Prescribing guidelines are unavailable. For physique- or performance-enhancing purposes, this drug is usually injected three times per week. The total weekly dosage is typically 200-400 mg, which is taken for 6-12 weeks. This level of use is sufficient to provide measurable gains in lean muscle mass and strength.

Drostanolone propionate is often combined with other steroids for an enhanced effect. Common stacks include an injectable anabolic such as Deca-Durabolin® (nandrolone decanoate) or Equipoise® (boldenone undecylenate), which can provide notably enhanced muscle gains without excessive water retention. For mass gains, it is often combined with an injectable testosterone. The result here can be solid muscle gain, with a lower level of water retention and other estrogenic side effects than if these steroids were used alone (usually in higher doses). Masteron, however, is most commonly applied during cutting phases of training. Here it is often combined with other non-aromatizable steroids such as Winstrol®, Primobolan®, Parabolan, or Anavar, which can greatly aid muscle retention and fat loss, during a period which can be very catabolic without steroids.

Administration (Women):
The prescribing guidelines for Drolban recommended a dose of 100 mg given three times per week. Therapy is given for a minimum of 8 to 12 weeks before an evaluation of its efficacy is made. If successful, the drug may be continued for as long as satisfactory results are obtained. Note that virilization symptoms were common at the recommended dosage. When used for physique- or performance-enhancing purposes, a dosage of 50 mg per week is most common, taken for 4 to 6 weeks. Virilization symptoms are rare in doses of 100 mg per week or below. Note that due to the short-acting nature of the propionate ester, the total weekly dosage is usually subdivided into smaller injections given once every second or third day.

Availability:
Drostanolone propionate is presently unavailable as a prescription drug product. There are limited supplies from export-oritented pharmaceutical companies, but the vast majority comes from underground steroid manufacturers.

“Oral tren” or methyltrienolone is a hormone that’s potency is rivaled only by its toxicity. I have used this compound twice in the past and I can’t think of any hormone that’s possess a higher fat loss potential. This is truly where methyltrienolone shines in my opinion. My lab work showed it was indeed liver toxic but dosed at 500 mcg a day superdrol dosed at 20 mg a day was harder on my liver. Due to its liver toxicity and extreme potency I can’t in good conscience recommend anyone run this compound. I will speak on my personal experience about it, but do not recommend anyone else run this compound.

Description:
Methyltrienolone is one of the strongest oral anabolic steroids ever produced. This agent is a derivative of trenbolone (trienolone), which has been c-17 alpha alkylated to allow for oral administration. This modification has created a steroid that is significantly stronger than its non-methylated cousin. Its potency has been measured to be anywhere from 120-300 times greater than that of methyltestosterone, with greater dissociation between anabolic and androgenic effects.535 536 Milligram for milligram methyltrienolone is a more active steroid than any agent sold on the commercial market, requiring doses as little as .5-1 milligram per day to notice a strong anabolic effect. Its potency is only matched by its relative toxicity, however, which has limited its modern use to that of laboratory research only.

History:
Methyltrienolone was first described in 1965.537 It was immediately identified as an extremely potent anabolic agent, far more potent than the commercially available agents of the time. In spite of its high relative activity, however, methyltrienolone has seen very limited use in humans. It was used clinically during the late 1960’s and early ’70’s, most notably in the treatment of advanced breast cancer. Here, its exceedingly strong anabolic/androgenic action helps the drug counter the local effects of endogenous estrogens, lending it some efficacy for slowing or even regressing tumor growth. Such application was not long lived, however, as more realistic evaluations of the drug’s toxicity soon led to its abandonment in human medicine.

By the mid-1970’s, methyltrienolone was becoming an accepted standard in non-human research studies, particularly those pertaining to the study of the androgen receptor activity. For this purpose the agent is very well suited. Its sheer potency and resistance to serum-binding proteins makes it an excellent in-vitro receptor-binding standard to compare other agents to. Being so resistant to metabolism, active methyltrienolone metabolites are also not going to greatly interfere with the results of most experiments. Body tissues can metabolize most steroids fairly easily, which means that even incubation studies can be complicated with the question of what is causing a particular effect, the steroid or one of its unidentified metabolites. This is much less of an issue with methyltrienolone. Today, methyltrienolone remains an agent of research use only.

How Supplied:
Methyltrienolone is not available as a commercial agent.

methyltrienolone molecule structure
Structural Characteristics:
Methyltrienolone is a modified form of nandrolone. It differs by: 1) the addition of a methyl group at carbon 17- alpha to protect the hormone during oral administration and 2) the introduction of double bonds at carbons 9 and 11, which increases its binding affinity and slows its metabolism. The resulting steroid is significantly more potent than its nandrolone base, and displays a much longer half-life and lower affinity for serum-binding proteins in comparison. Methyltrienolone chemically differs from trenbolone only by the addition of a methyl group at c-17. This alteration changes the activity of methyltrienolone considerably, however, such that this agent should not simply be considered an oral form of trenbolone.

Side Effects (Estrogenic):
Methyltrienolone is not aromatized by the body, and is not measurably estrogenic. It is of note, however, that methyltrienolone displays significant binding affinity for the progesterone receptor.538 The side effects associated with progesterone are similar to those of estrogen, including negative feedback inhibition of testosterone production and enhanced rate of fat storage. Progestins also augment the stimulatory effect of estrogens on mammary tissue growth. There appears to be a strong synergy between these two hormones here, such that gynecomastia might even occur with the help of progestins, without excessive estrogen levels. The use of an anti-estrogen, which inhibits the estrogenic component of this disorder, is often sufficient to mitigate gynecomastia caused by progestational anabolic/androgenic steroids.

Side Effects (Androgenic):
Although classified as an anabolic steroid, androgenic side effects are still common with this substance. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are also warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Additionally, the 5-alpha reductase enzyme does not metabolize methyltrienolone, so its relative androgenicity is not affected by finasteride or dutasteride.

Side Effects (Hepatotoxicity):
Methyltrienolone is a c17-alpha alkylated compound. This alteration protects the drug from deactivation by the liver, allowing a very high percentage of the drug entry into the bloodstream following oral administration. C17-alpha alkylated anabolic/androgenic steroids can be hepatotoxic. Prolonged or high exposure may result in liver damage. In rare instances life-threatening dysfunction may develop. It is advisable to visit a physician periodically during each cycle to monitor liver function and overall health. Intake of c17-alpha alkylated steroids is commonly limited to 6-8 weeks, in an effort to avoid escalating liver strain.

Methyltrienolone is an exceedingly potent oral steroid, with a very high level of resistance to hepatic metabolism. This makes methyltrienolone exceedingly liver-toxic, precluding its use as a prescription agent at this time, in any part of the world. Studies published from the University of Bonn Germany back in 1966 make this very clear.539 In fact, at this time researchers had deemed this the most liver-toxic steroid to ever be studied in humans, summing up their findings well when stating:

“Methyltrienolone… which is orally active as an anabolic agent in a dose less than 1.0 mg per day in normal adults,has been tested with regard to its influence on liver function. As measured by multiple parameters (BSP retention; total bilirubin; activities of transaminases, alkaline phosphates and cholinesterase in serum; activity of proaccelerin in plasma) methyltrienolone turned out to be very active as to causing biochemical symptoms of intrahepatic cholestasis. …thus methyltrienolone at present being the most ‘hepatotoxic’ steroid.”

The use of a liver detoxification supplement such as Liver Stabil, Liv-52, or Essentiale Forte is advised while taking any hepatotoxic anabolic/androgenic steroids.

Side Effects (Cardiovascular):
Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Although not extensively studied in humans, the oral route, high relative potency, and non-aromatizable nature of methyltrienolone suggest that this agent is extremely prone to negatively altering lipid values and increasing atherogenic risk. Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction.

To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.

Side Effects (Testosterone Suppression):
All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.

The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects page.

Administration (General):
Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability.540 This is caused by the fat-soluble nature of steroid hormones, which can allow some of the drug to dissolve with undigested dietary fat, reducing its absorption from the gastrointestinal tract. For maximum utilization, methyltrienolone should be taken on an empty stomach.

Administration (Men):
Methyltrienolone is no longer used in clinical medicine due to an unacceptable level of hepatotoxicity. This agent is generally not recommended for physique- or performance-enhancing purposes for the same reason. Those absolutely insisting on its use need to take its level of liver toxicity very seriously. At the very least, routine blood tests should be conducted to ensure the agent is not imparting damage. Drug duration should also be very limited, preferably to 4 weeks of use or less. The relative potency of methyltrienolone is extremely high, requiring doses as little as .5 milligram per day. Its effective and tolerable range is usually considered to be .5 to 2mg per day. Dianabol-type doses of 20-30 mg daily are completely unthinkable, and should never be attempted. Again, this is an extremely toxic steroid, and all good advice would say to avoid it. Any one of the many commercially available steroids would be much safer choices.

Administration (Women):
Methyltrienolone is no longer used in clinical medicine due to an unacceptable level of hepatotoxicity. This agent is not recommended for women for physique- or performance-enhancing purposes due to its extremely strong toxicity and tendency to produce virilizing side effects.

Availability:
Methyltrienolone is not produced as a prescription steroid product in any part of the world. With the rapid expansion of underground steroid manufacturers, this agent has been released as a black market designer compound. Those contemplating the use of underground forms of methyltrienolone should consider that such agents are being released for human use without any government approval or consideration to its safety.

Proviron is the topic of today. There is a lot of controversy surrounding this hormone particularly in regards to it being suppressive or not. I have played with Proviron many times and my lab work shows it is suppressive. I actually ran what’s I called the Proviron experiment one time determine if it was or not. It’s a pretty fascinating hormone to say the least.

Androgenic: 30-40
Anabolic 100-150
Standard Testosterone propionate
Chemical Names 17beta-hydroxy-1alpha-methyl-5alpha-androstan-3-one, 1-methyl-5alpha-dihydrotestosterone
Estrogenic Activity none
Progestational Activity not significant
Description:
Proviron is Schering’s (now Bayer’s) brand name for the oral androgen mesterolone (1-methyl dihydrotestosterone). Similar to dihydrotestosterone, mesterolone is a strong androgen with only a weak level of anabolic activity. This is due to the fact that like dihydrotestosterone, mesterolone is rapidly reduced to inactive diol metabolites in muscle tissue where concentrations of the 3-hydroxysteroid dehydrogenase enzyme are high. The belief that the weak anabolic nature of this compound indicates a tendency to block the androgen receptor in muscle tissue, thereby reducing the gains of other more potent muscle-building steroids, should likewise not be taken seriously. In fact, due to its extremely high affinity for plasma binding proteins such as SHBG, mesterolone may actually work to potentate the activity of other steroids by displacing a higher percentage into a free, unbound state. Among athletes, mesterolone is primarily used to increase androgen levels when dieting or preparing for a contest, and as an anti-estrogen due to its intrinsic ability to antagonize the aromatase enzyme.

History:
According to company literature, Schering developed Proviron® in 1934, making this is an extremely old medication as far as anabolic/androgenic steroids. Schering also states that it was the first medication put into clinical practice for the treatment of “hormone-related diseases and complaints in men. ”Accordingly, mesterolone would have been developed around the same time as methyltestosterone (1935) and testosterone propionate (1937), which are both very old agents generally considered obsolete by today’s standards. In spite of its age, Proviron has a long history of clinical effectiveness and safety, and remains in widespread clinical use today. It is generally prescribed to males for the treatment of declining physical and mental capacity caused by age and subnormal androgen levels, low libido caused by insufficient androgen levels, hypogonadism (in pre- and post-pubescent males), and infertility (in certain situations mesterolone increases the quality and quantity of sperm).

The use of mesterolone as a fertility aid is perhaps one of the most controversial indications for this drug considering that anabolic/androgenic steroids are generally linked to infertility. It is also a use of mesterolone that is quite often misunderstood by athletes. Mesterolone is applicable here because it is an effective androgen that offers minimal suppression of gonadotropins in normal therapeutic doses, not because it increases LH output. Absent gonadotropin suppression, the drug may supplement androgenicity necessary for sperm production. It is well understood that androgens have direct stimulatory effects on spermatogenesis, and also influence the transportation and maturation of sperm via effects on the epididymis, ductus deferens, and seminal vesicles. So the role of these hormones is not entirely suppressive. Mesterolone seems to have a unique positive influence on certain cases of male fertility because its potential stimulatory effects on sperm quantity and quality are not overridden by the suppression of gonadotropins.

Mesterolone is widely manufactured by Bayer (formerly Schering), which currently sells the drug in more than thirty countries worldwide. The most common brand name used for its sale is Proviron, although Schering/Bayer has sold the agent under other names in certain markets, including Mestoranum and Provironum. Additionally, other manufacturers have sold mesterolone over the years, appearing under such brand names as Pluriviron (Asche, Germany), Vistimon (Jenepharm, Germany), and Restore (Brown & Burke, India). In spite of its long track record of safety and efficacy, mesterolone was never approved for sale in the United States. It remains available in many Western nations, however. Bayer remains the major (almost exclusive) global supplier of mesterolone today, although on rare occasion other brands of the drug can be located.

How Supplied:
Proviron is widely available in human drug markets. Composition and dosage may vary by country and manufacturer; preparations generally contain 25 mg or 50 mg of steroid per tablet.

proviron mesterolone structure molecule
Structural Characteristics:
Mesterolone is a modified form of dihydrotestosterone. It differs by the addition of a methyl group at carbon 1, which helps protect the hormone from hepatic metabolism during oral administration. The same structural modification is also used with oral Primobolan® (methenolone) tablets. Alkylation at the one position slows hepatic metabolism of the steroid during the first pass, although much less profoundly than c-17 alpha alkylation. Mesterolone is resistant enough to breakdown to allow therapeutically beneficial blood levels to be achieved, although the overall bioavailability remains much lower than c-17 alpha alkylated oral steroids. Mesterolone also has a very strong binding affinity for Sex Hormone Binding Globulin.572 This may act to displace other steroids more weakly bound to SHBG into a free (active) state.

Side Effects (Estrogenic):
Mesterolone is not aromatized by the body, and is not measurably estrogenic. An anti-estrogen is not necessary when using this steroid, as the drug is unlikely to induce gynecomastia, water retention, or other estrogen-related side effects.

Mesterolone is actually believed to act as an anti-aromatase in the body, preventing or slowing the conversion of steroids into estrogen. The result is somewhat comparable to Arimidex®, although less profound. The anti-estrogenic properties of mesterolone are not unique, and a number of other steroids have demonstrated similar activity. Dihydrotestosterone and Masteron (2-methyl-dihydrotestosterone), for example, have been successfully used as therapies for gynecomastia and breast cancer due to their strong androgenic and potentially anti-estrogenic effect. It has also been suggested that nandrolone may even lower aromatase activity in peripheral tissues where it is more resistant to estrogen conversion (the most active site of nandrolone aromatization seems to be the liver). The anti-estrogenic effect of all of these compounds is presumably caused by their ability to compete with other substrates for binding to the aromatase enzyme. With the aromatase enzyme bound to the steroid, yet being unable to alter it, an inhibiting effect is achieved as it is temporarily blocked from interacting with other hormones.

Side Effects (Androgenic):
Mesterolone is classified as an androgenic steroid. Androgenic side effects are common with this substance, especially with higher doses. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are also warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Additionally, the 5-alpha reductase enzyme does not metabolize mesterolone, so its relative androgenicity is not affected by finasteride or dutasteride.

Side Effects (Hepatotoxicity):
Mesterolone is not c17-alpha alkylated, and not known to produce hepatotoxic effects; liver toxicity is unlikely.

Side Effects (Cardiovascular):
Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Mesterolone is an oral non-aromatizable androgen, and expected to have a notable negative effect on lipids. Studies administering 100 mg of mesterolone per day to hypogonadal men for approximately 6 months demonstrated a significant increase in total cholesterol (18.8%) and LDL cholesterol (65.2%), accompanied by a significant decrease in HDL cholesterol (-35.7%).573

Mesterolone should not be used when cardiovascular risk factors preclude the use of other oral steroids.

To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.

Side Effects (Testosterone Suppression):
Mesterolone has a very weak suppressive effect on gonadotropins and serum testosterone. Studies show that when given in moderate doses (150 mg per day or less), significant suppression of testosterone levels does not occur.574 In studies with higher doses (300 mg per day and above), the agent strongly suppressed serum testosterone.575

The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects section of this book.

Administration (Men):
To treat androgen insufficiency, Proviron is usually given in a dose of 1 tablet (25 mg) three times per day at the initiation of therapy. The drug is later continued at a lower maintenance dose, which usually consists of taking 1 tablet (25 mg) one to two times per day. Similar doses are used to support male fertility, usually in conjunction with other fertility drugs like injectable FSH. The usual dosage among male athletes is between 50 mg and 150 mg of mesterolone per day, or two to six 25 mg tablets. The drug is typically taken in cycles of 6-12 weeks in length, which is usually a sufficient period of time to notice the benefits of drug therapy.

Many bodybuilders favor the use of mesterolone during dieting phases or contest preparation, when low estrogen and high androgen levels are particularly desirable. This is especially beneficial when anabolics like Winstrol®, Anavar, or Primobolan® are being used alone, as the androgenic content of these drugs is relatively low. Mesterolone can be effectively used here to adjust the androgen to estrogen ratio upwards, bringing about an increase in the hardness and density of the muscles, supporting libido and general sense of well being, and increasing the tendency to burn body fat. It is also commonly used (at a similar dosage) to prevent gynecomastia when other aromatizable steroids are being administered, often in conjunction with 10-20 mg per day of Nolvadex.

Administration (Women):
Proviron is not approved for use in women. This agent is not recommended for women for physique- or performance-enhancing purposes due to its strong androgenic nature and tendency to produce virilizing side effects. Some women do favor the drug, however, and find a single 25 mg tablet enough to efficiently shift the hormone balance in the body, greatly impacting the look of definition to the physique. Intake is usually limited to no longer than four or five weeks in such situations to minimize the chance of developing lasting virilizing effects. One tablet used in conjunction with 10 or 20 mg of Nolvadex® can be even more efficient for muscle hardening, creating an environment here the body is much more inclined to burn off extra body fat, especially in female trouble areas like the hips and thighs. Extreme caution should be taken with such use, however.

Availability:
Mesterolone remains widely available, the vast majority of products made by or under license from Bayer; most commonly under the Proviron trade name.

Your welcome man. I am glad everyone is enjoying the posts. I post them here because I am a board Rep for basic/pcom. The administrators I guess haven’t had time to change my title. I have never been one to use the forums for knowledge. Over the years I have discovered that a lot of steroid information is mixed with bro lore. I don’t believe in spreading bro lore/ bro science. My information on hormones comes from three places. William Llewellyn’s book “Anabolics”, Anabolic Pharmacology by Seth Roberts, and medical journals/ studies. I want solid verifiable information readily available on the Basicstero thread.

I am glad everyone here is enjoying the posts. I have more to come so stay tuned. I do need some help though. I cannot decide whether to run posts on hormones that I have already covered that differ only by ester i.e. tren e, npp, test e and c etc. What do you guys think?

Thanks for the input man. I will take your advice and throw them in. I thought about including prohomones but they don’t exists anymore that I know of, the good ones at least. I still may throw them in though, because I have some steroids that no ones makes anymore that I am going to include. If you want to see something specify let me know.

[h=3]Description:[/h][FONT=&quot]Winstrol is the most widely recognized trade name for the drug stanozolol. Stanozolol is a derivative of dihydrotestosterone, chemically altered so that the hormone’s anabolic (tissue-building) properties are greatly amplified and its androgenic activity minimized. Stanozolol is classified as an “anabolic” steroid, and exhibits one of the strongest dissociations of anabolic to androgenic effect among commercially available agents. It also cannot be aromatized into estrogens. Stanozolol is the second most widely used oral steroid, succeeded in popularity only by Dianabol (methandrostenolone). It is favored for its ability to promote muscle growth without water-retention, making it highly valued by dieting bodybuilders and competitive athletes.[/FONT]
[h=3]History:[/h][FONT=&quot]Stanozolol was first described in 1959.[SUP]613[/SUP] It was developed into a medicine by Winthrop Laboratories in Great Britain. Parent firm (Sterling) filed for U.S. patent on the agent in 1961.[SUP]614[/SUP] Stanozolol was officially released to the U.S. prescription drug market in 1962 under the brand name Winstrol. Stanozolol was initially prescribed for a variety of medical purposes, including the induction of appetite and lean tissue gain in cases of weight loss associated with many malignant and non-malignant diseases, the preservation of bone mass during osteoporosis, the promotion of liner growth in children with growth failure, as an anti-catabolic during prolonged corticosteroid therapy or for post-operative and post-trauma (burns, fractures) patients, and even to treat debility in the elderly.[/FONT]
[FONT=&quot]The FDA’s control over the prescription drug market had tightened by the mid-1970’s, and the indicated uses for Winstrol were soon narrowed. During this time the FDA officially supported that Winstrol was “Probably Effective” as an adjunct therapy for treating osteoporosis, and for promoting growth in pituitary-deficient dwarfism. With this position, Winthrop was given more time to sell and study the agent. Winthrop was able to continually satisfy the FDA regarding Winstrol’s validity as a therapeutic agent, and it remained in the U.S. throughout the 1980’s and 1990’s, a time when many other anabolic steroids were disappearing from the marketplace. Stanozolol was also showing some promise during this period for improving red blood cell concentrations, combating breast cancer, and (more recently) treating angioedema, a disorder characterized by the swelling of subdermal tissues, often with hereditary causes.[/FONT]
[FONT=&quot]Winthrop went through a number of corporate changes during the 1990’s, including a 1991 merger with Elf Sanofi to form Sanofi Winthrop. Sanofi Winthrop continued on to sell Winstrol in the U.S. for approximately 10 more years, before finally discontinuing the medication because of “manufacturing issues” (Searle was actually making the product for Sanofi at the time, and had reportedly ceased production). In 2003, the rights to Winstrol were officially transferred to Ovation Pharmaceuticals. Winstrol remains an approved drug on the U.S. pharmaceutical market, although is not under active production by Ovation label. All forms of Winstrol are presently unavailable in the U.S., although the Winstrol brand remains available in Spain. Numerous other brands and generic forms of the drug are produced in other countries, in both human and veterinary drug markets.[/FONT]
[h=3]How Supplied:[/h][FONT=&quot]Stanozolol is widely available in both human and veterinary drug markets. Composition and dosage may vary by country and manufacturer. Stanozolol was originally designed as an oral anabolic steroid, containing 2mg of drug per tablet (Winstrol). Other brands commonly contain 5 mg or 10 mg per tablet. Stanozolol can also be found in injectable preparations. These are most commonly water-based suspensions carrying 50 mg/ml of steroid.[/FONT]
[FONT=&quot]

[/FONT]
[h=3]Structural Characteristics:[/h][FONT=&quot]Stanozolol is a modified form of dihydrotestosterone. It differs by: 1) the addition of a methyl group at carbon 17-alpha to protect the hormone during oral administration and 2) the attachment of a pyrazol group to the A-ring, replacing the normal 3-keto group (this gives stanozolol the chemical classification of a heterocyclic steroid). When viewed in the light of 17-alpha methyldihydrotestosterone, the A-ring modification on stanozolol seems to considerably increase its anabolic strength while reducing its relative androgenicity.[/FONT]
[FONT=&quot]Stanozolol has a much weaker relative binding affinity for the androgen receptor than testosterone or dihydrotestosterone. At the same time it displays a much longer half-life and lower affinity for serum binding proteins in comparison. These features (among others) allow stanozolol to be a very potent anabolic steroid in spite of a weaker affinity for receptor binding. Recent studies have additionally confirmed that its primary mode if action involves interaction with the cellular androgen receptor.[SUP]615[/SUP] Although not fully elucidated, stanozolol may have additional (some potentially unique) properties with regard to antagonism of the progesterone receptor, Low Affinity Glucocorticoid-binding Site interaction, and AR/PR/GR independent activities.[SUP]616 617 618[/SUP]In therapeutic doses stanozolol does not have significant progestational activity.[SUP]619[/SUP][/FONT]
[FONT=&quot]Stanozolol is known to strongly suppress levels of SHBG (sex hormone-binding globulin). This trait is characteristic of all anabolic/androgenic steroids, although its potency and form of administration make oral Winstrol® particularly effective in this regard. One study with a group of 25 normal males demonstrated a 48.4% reduction in SHBG after only 3 days of use.[SUP]620[/SUP]The dose administered was .2mg/kg, or roughly 18mg for a person weighing 200lbs. Plasma binding proteins such as SHBG act to temporarily constrain steroid hormones from exerting activity in the body, and effectively reduce the available percentage of free (active) steroid. Oral stanozolol may be useful for providing a greater percentage of unbound steroid in the body, especially when taken in combination with a hormone that is more avidly bound by SHBG, such as testosterone.[/FONT]
[h=3]Side Effects (Estrogenic):[/h][FONT=&quot]Stanozolol is not aromatized by the body, and is not measurably estrogenic. An anti-estrogen is not necessary when using this steroid, as gynecomastia should not be a concern even among sensitive individuals. Since estrogen is the usual culprit with water retention, stanozolol instead produces a lean, quality look to the physique with no fear of excess subcutaneous fluid retention. This makes it a favorable steroid to use during cutting cycles, when water and fat retention are major concerns. Stanozolol is also very popular among athletes in combination strength/speed sports such as Track and Field. In such disciplines one usually does not want to carry around excess water weight, and may find the raw muscle-growth brought about by stanozolol to be quite favorable over the lower quality mass gains of aromatizable agents.[/FONT]
[h=3]Side Effects (Androgenic):[/h][FONT=&quot]Although classified as an anabolic steroid, androgenic side effects are still common with this substance. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are also warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Additionally, the 5-alpha reductase enzyme does not metabolize stanozolol, so its relative androgenicity is not affected by finasteride or dutasteride. Stanozolol is a steroid with relatively low androgenic activity in relation to its tissue-building actions, making the threshold for strong androgenic side effects comparably higher than more androgenic agents such as testosterone, methandrostenolone, or fluoxymesterone.[/FONT]
[h=3]Side Effects (Hepatotoxicity):[/h][FONT=&quot]Stanozolol is a c17-alpha alkylated compound. This alteration protects the drug from deactivation by the liver, allowing a very high percentage of the drug entry into the bloodstream following oral administration. C17-alpha alkylated anabolic/androgenic steroids can be hepatotoxic. Prolonged or high exposure may result in liver damage. In rare instances life-threatening dysfunction may develop. It is advisable to visit a physician periodically during each cycle to monitor liver function and overall health. Intake of c17-alpha alkylated steroids is commonly limited to 6-8 weeks, in an effort to avoid escalating liver strain.[/FONT]
[FONT=&quot]Stanozolol appears to offer less hepatic stress than an equivalent dose of Dianabol (methandrostenolone). Studies giving 12mg of stanozolol per day for 27 weeks failed to demonstrate clinically-significant changes in markers of liver function, including serum aspartate amino-transferase, alanine amino-transferase, gamma-glutamyltransferase, bilirubin, and alkaline phosphatase.[SUP]621[/SUP] Relative hepatotoxicity increases as the dosage escalates, so hepatic dysfunction should still be a concern. In rare instances, high doses (alone or in combination with other steroids) have been implicated in cases of serious life-threatening hepatotoxicity in bodybuilders. Injectable stanozolol has also been implicated in severe hepatotoxicity in an otherwise healthy bodybuilder,[SUP]622[/SUP] and should not be used as an alternative medication when liver toxicity precludes oral stanozolol use.[/FONT]
[FONT=&quot]The use of a liver detoxification supplement such as Liver Stabil, Liv-52, or Essentiale Forte is advised while taking any hepatotoxic anabolic/androgenic steroids.[/FONT]
[h=3]Side Effects (Cardiovascular):[/h][FONT=&quot]Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Stanozolol has a strong effect on the hepatic management of cholesterol due to its structural resistance to liver breakdown, non-aromatizable nature, and route of administration. Studies using an oral dose of 6 mg per day for six weeks demonstrated a mean serum HDL reduction of 33% in healthy male weight-training subjects, which was combined with a 29% increase in serum LDL.[SUP]623[/SUP]Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction. Injectable stanozolol has also been documented to produce strong negative changes in serum lipids. One study was carried out on a group of 12 healthy male subjects, and demonstrated a measurable reduction in HDL cholesterol values, as well as an increase in LDL and total cholesterol values, following a single injection of 50 mg.[SUP]624[/SUP] These changes persisted for 4 weeks after the drug was administered, and represent a potential increased risk for developing arteriosclerosis. Injectable stanozolol should not be used as an alternative medication when cardiovascular risk factors preclude oral stanozolol use.[/FONT]
[FONT=&quot]To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.[/FONT]
[h=3]Side Effects (Testosterone Suppression):[/h][FONT=&quot]All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Stanozolol is no exception, and is noted for its strong influence on the hypothalamic-pituitary-testicular axis. Clinical studies giving 10 mg per day to healthy male subjects for 14 days caused the mean plasma testosterone level to fall by 55%.[SUP]625[/SUP] Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.[/FONT]
[FONT=&quot]The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects section.[/FONT]
[h=3]Administration (General):[/h][FONT=&quot]Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability.[SUP]626[/SUP] This is caused by the fat-soluble nature of steroid hormones, which can allow some of the drug to dissolve with undigested dietary fat, reducing its absorption from the gastrointestinal tract. For maximum utilization, oral forms of stanozolol should be taken on an empty stomach.[/FONT]
[FONT=&quot]There can be large discrepancies in the steroid particle size between injectable stanozolol preparations. For example, Winstrol from Zambon (Spain) was designed for human use, and uses a refined powder that will pass through a 27-gauge needle. Winstrol®-V is a veterinary product in the U.S. and Canada, and has larger particles that will jam in needles smaller than 22-gauge. Solutions that utilize a larger particle size may also cause more discomfort at the site of injection. Injectable forms of stanozolol can be taken in measured oral doses should injection prove intolerable.[/FONT]
[h=3]Administration (Men):[/h][FONT=&quot]The original prescribing guidelines for Winstrol called for a daily dosage of 6 mg, which was administered on a schedule of one 2 mg tablet three times per day. The usual dosage for physique- or performance-enhancing purposes is between 15 mg and 25 mg per day, or three to five 5 mg tablets, taken for no longer than 6-8 weeks. Injectable Winstrol is generally recommended at a clinical dosage of one 50 mg injection every 2-3 weeks. When used for physique- or performance-enhancing purposes, a dosage of 50 mg every other day is most commonly applied. Veterinary stanozolol preparations with a larger particle size will be more slowly dispersed by the body, and are commonly given at 75 mg every third day. Doses of 50 mg per day with injectable stanozolol are not uncommon, although probably not advised. Note that injectable forms of the drug are expected to have, milligram for milligram, a greater anabolic effect than oral.[SUP]627[/SUP][/FONT]
[FONT=&quot]Stanozolol is often combined with other steroids for a more dramatic result. For example, while bulking one might opt to add in 200-400 mg of a testosterone ester (cypionate, enanthate, or propionate) per week. The result should be a considerable gain in new muscle mass, with a more comfortable level of water and fat retention than if taking a higher dose of testosterone alone. For dieting phases, one might alternately combine stanozolol with a non-aromatizing steroid such as 150 mg per week of a trenbolone ester or 200-300 mg of Primobolan® (methenolone enanthate). Such stacks are highly favored for increasing definition and muscularity. An in-between (lean mass gain) might be to add in 200-400 mg of a low estrogenic compound like Deca-Durabolin® (nandrolone decanoate) or Equipoise® (boldenone undecylenate).[/FONT]
[h=3]Administration (Women):[/h][FONT=&quot]The original prescribing guidelines for Winstrol called for a daily dosage of 4 mg (one 2mg tablet twice daily) with young women particularly susceptible to the androgenic effects of anabolic steroids. This dosage was increased to 6mg (the same as the recommended dose for males) when necessary. When used for physique- or performance-enhancing purposes, a dosage of 5 mg to 10 mg daily is most common, taken for no longer than 4-6 weeks. Injectable Winstrol is generally recommended at a clinical dose of 50 mg every 2-3 weeks. The injectable is usually not advised with women for physique- or performance-enhancing purposes, as it allows for less control over blood hormone levels. Those women who absolutely must use the injectable commonly administer 25 mg every 3 or 4 days. Although this compound is weakly androgenic, the risk of virilization symptoms cannot be completely excluded, even at therapeutic doses.[/FONT]
[h=3]Availability:[/h][FONT=&quot]Stanozolol remains widely available as a pharmaceutical product. Its production has been shifting to less regulated markets (mainly in Asia) in recent years, however, which likely reflects declining interest in using stanozolol as a medicinal product in the West, and the continuing high demand for this drug among athletes and bodybuilders.[/FONT]

[h=3]Description:[/h][FONT=&quot]Winstrol is the most widely recognized trade name for the drug stanozolol. Stanozolol is a derivative of dihydrotestosterone, chemically altered so that the hormone’s anabolic (tissue-building) properties are greatly amplified and its androgenic activity minimized. Stanozolol is classified as an “anabolic” steroid, and exhibits one of the strongest dissociations of anabolic to androgenic effect among commercially available agents. It also cannot be aromatized into estrogens. Stanozolol is the second most widely used oral steroid, succeeded in popularity only by Dianabol (methandrostenolone). It is favored for its ability to promote muscle growth without water-retention, making it highly valued by dieting bodybuilders and competitive athletes.[/FONT]
[h=3]History:[/h][FONT=&quot]Stanozolol was first described in 1959.[SUP]613[/SUP] It was developed into a medicine by Winthrop Laboratories in Great Britain. Parent firm (Sterling) filed for U.S. patent on the agent in 1961.[SUP]614[/SUP] Stanozolol was officially released to the U.S. prescription drug market in 1962 under the brand name Winstrol. Stanozolol was initially prescribed for a variety of medical purposes, including the induction of appetite and lean tissue gain in cases of weight loss associated with many malignant and non-malignant diseases, the preservation of bone mass during osteoporosis, the promotion of liner growth in children with growth failure, as an anti-catabolic during prolonged corticosteroid therapy or for post-operative and post-trauma (burns, fractures) patients, and even to treat debility in the elderly.[/FONT]
[FONT=&quot]The FDA’s control over the prescription drug market had tightened by the mid-1970’s, and the indicated uses for Winstrol were soon narrowed. During this time the FDA officially supported that Winstrol was “Probably Effective” as an adjunct therapy for treating osteoporosis, and for promoting growth in pituitary-deficient dwarfism. With this position, Winthrop was given more time to sell and study the agent. Winthrop was able to continually satisfy the FDA regarding Winstrol’s validity as a therapeutic agent, and it remained in the U.S. throughout the 1980’s and 1990’s, a time when many other anabolic steroids were disappearing from the marketplace. Stanozolol was also showing some promise during this period for improving red blood cell concentrations, combating breast cancer, and (more recently) treating angioedema, a disorder characterized by the swelling of subdermal tissues, often with hereditary causes.[/FONT]
[FONT=&quot]Winthrop went through a number of corporate changes during the 1990’s, including a 1991 merger with Elf Sanofi to form Sanofi Winthrop. Sanofi Winthrop continued on to sell Winstrol in the U.S. for approximately 10 more years, before finally discontinuing the medication because of “manufacturing issues” (Searle was actually making the product for Sanofi at the time, and had reportedly ceased production). In 2003, the rights to Winstrol were officially transferred to Ovation Pharmaceuticals. Winstrol remains an approved drug on the U.S. pharmaceutical market, although is not under active production by Ovation label. All forms of Winstrol are presently unavailable in the U.S., although the Winstrol brand remains available in Spain. Numerous other brands and generic forms of the drug are produced in other countries, in both human and veterinary drug markets.[/FONT]
[h=3]How Supplied:[/h][FONT=&quot]Stanozolol is widely available in both human and veterinary drug markets. Composition and dosage may vary by country and manufacturer. Stanozolol was originally designed as an oral anabolic steroid, containing 2mg of drug per tablet (Winstrol). Other brands commonly contain 5 mg or 10 mg per tablet. Stanozolol can also be found in injectable preparations. These are most commonly water-based suspensions carrying 50 mg/ml of steroid.[/FONT]

[h=3]Structural Characteristics:[/h][FONT=&quot]Stanozolol is a modified form of dihydrotestosterone. It differs by: 1) the addition of a methyl group at carbon 17-alpha to protect the hormone during oral administration and 2) the attachment of a pyrazol group to the A-ring, replacing the normal 3-keto group (this gives stanozolol the chemical classification of a heterocyclic steroid). When viewed in the light of 17-alpha methyldihydrotestosterone, the A-ring modification on stanozolol seems to considerably increase its anabolic strength while reducing its relative androgenicity.[/FONT]
[FONT=&quot]Stanozolol has a much weaker relative binding affinity for the androgen receptor than testosterone or dihydrotestosterone. At the same time it displays a much longer half-life and lower affinity for serum binding proteins in comparison. These features (among others) allow stanozolol to be a very potent anabolic steroid in spite of a weaker affinity for receptor binding. Recent studies have additionally confirmed that its primary mode if action involves interaction with the cellular androgen receptor.[SUP]615[/SUP] Although not fully elucidated, stanozolol may have additional (some potentially unique) properties with regard to antagonism of the progesterone receptor, Low Affinity Glucocorticoid-binding Site interaction, and AR/PR/GR independent activities.[SUP]616 617 618[/SUP]In therapeutic doses stanozolol does not have significant progestational activity.[SUP]619[/SUP][/FONT]
[FONT=&quot]Stanozolol is known to strongly suppress levels of SHBG (sex hormone-binding globulin). This trait is characteristic of all anabolic/androgenic steroids, although its potency and form of administration make oral Winstrol® particularly effective in this regard. One study with a group of 25 normal males demonstrated a 48.4% reduction in SHBG after only 3 days of use.[SUP]620[/SUP]The dose administered was .2mg/kg, or roughly 18mg for a person weighing 200lbs. Plasma binding proteins such as SHBG act to temporarily constrain steroid hormones from exerting activity in the body, and effectively reduce the available percentage of free (active) steroid. Oral stanozolol may be useful for providing a greater percentage of unbound steroid in the body, especially when taken in combination with a hormone that is more avidly bound by SHBG, such as testosterone.[/FONT]
[h=3]Side Effects (Estrogenic):[/h][FONT=&quot]Stanozolol is not aromatized by the body, and is not measurably estrogenic. An anti-estrogen is not necessary when using this steroid, as gynecomastia should not be a concern even among sensitive individuals. Since estrogen is the usual culprit with water retention, stanozolol instead produces a lean, quality look to the physique with no fear of excess subcutaneous fluid retention. This makes it a favorable steroid to use during cutting cycles, when water and fat retention are major concerns. Stanozolol is also very popular among athletes in combination strength/speed sports such as Track and Field. In such disciplines one usually does not want to carry around excess water weight, and may find the raw muscle-growth brought about by stanozolol to be quite favorable over the lower quality mass gains of aromatizable agents.[/FONT]
[h=3]Side Effects (Androgenic):[/h][FONT=&quot]Although classified as an anabolic steroid, androgenic side effects are still common with this substance. This may include bouts of oily skin, acne, and body/facial hair growth. Anabolic/androgenic steroids may also aggravate male pattern hair loss. Women are also warned of the potential virilizing effects of anabolic/androgenic steroids. These may include a deepening of the voice, menstrual irregularities, changes in skin texture, facial hair growth, and clitoral enlargement. Additionally, the 5-alpha reductase enzyme does not metabolize stanozolol, so its relative androgenicity is not affected by finasteride or dutasteride. Stanozolol is a steroid with relatively low androgenic activity in relation to its tissue-building actions, making the threshold for strong androgenic side effects comparably higher than more androgenic agents such as testosterone, methandrostenolone, or fluoxymesterone.[/FONT]
[h=3]Side Effects (Hepatotoxicity):[/h][FONT=&quot]Stanozolol is a c17-alpha alkylated compound. This alteration protects the drug from deactivation by the liver, allowing a very high percentage of the drug entry into the bloodstream following oral administration. C17-alpha alkylated anabolic/androgenic steroids can be hepatotoxic. Prolonged or high exposure may result in liver damage. In rare instances life-threatening dysfunction may develop. It is advisable to visit a physician periodically during each cycle to monitor liver function and overall health. Intake of c17-alpha alkylated steroids is commonly limited to 6-8 weeks, in an effort to avoid escalating liver strain.[/FONT]
[FONT=&quot]Stanozolol appears to offer less hepatic stress than an equivalent dose of Dianabol (methandrostenolone). Studies giving 12mg of stanozolol per day for 27 weeks failed to demonstrate clinically-significant changes in markers of liver function, including serum aspartate amino-transferase, alanine amino-transferase, gamma-glutamyltransferase, bilirubin, and alkaline phosphatase.[SUP]621[/SUP] Relative hepatotoxicity increases as the dosage escalates, so hepatic dysfunction should still be a concern. In rare instances, high doses (alone or in combination with other steroids) have been implicated in cases of serious life-threatening hepatotoxicity in bodybuilders. Injectable stanozolol has also been implicated in severe hepatotoxicity in an otherwise healthy bodybuilder,[SUP]622[/SUP] and should not be used as an alternative medication when liver toxicity precludes oral stanozolol use.[/FONT]
[FONT=&quot]The use of a liver detoxification supplement such as Liver Stabil, Liv-52, or Essentiale Forte is advised while taking any hepatotoxic anabolic/androgenic steroids.[/FONT]
[h=3]Side Effects (Cardiovascular):[/h][FONT=&quot]Anabolic/androgenic steroids can have deleterious effects on serum cholesterol. This includes a tendency to reduce HDL (good) cholesterol values and increase LDL (bad) cholesterol values, which may shift the HDL to LDL balance in a direction that favors greater risk of arteriosclerosis. The relative impact of an anabolic/androgenic steroid on serum lipids is dependant on the dose, route of administration (oral vs. injectable), type of steroid (aromatizable or non-aromatizable), and level of resistance to hepatic metabolism. Stanozolol has a strong effect on the hepatic management of cholesterol due to its structural resistance to liver breakdown, non-aromatizable nature, and route of administration. Studies using an oral dose of 6 mg per day for six weeks demonstrated a mean serum HDL reduction of 33% in healthy male weight-training subjects, which was combined with a 29% increase in serum LDL.[SUP]623[/SUP]Anabolic/androgenic steroids may also adversely affect blood pressure and triglycerides, reduce endothelial relaxation, and support left ventricular hypertrophy, all potentially increasing the risk of cardiovascular disease and myocardial infarction. Injectable stanozolol has also been documented to produce strong negative changes in serum lipids. One study was carried out on a group of 12 healthy male subjects, and demonstrated a measurable reduction in HDL cholesterol values, as well as an increase in LDL and total cholesterol values, following a single injection of 50 mg.[SUP]624[/SUP] These changes persisted for 4 weeks after the drug was administered, and represent a potential increased risk for developing arteriosclerosis. Injectable stanozolol should not be used as an alternative medication when cardiovascular risk factors preclude oral stanozolol use.[/FONT]
[FONT=&quot]To help reduce cardiovascular strain it is advised to maintain an active cardiovascular exercise program and minimize the intake of saturated fats, cholesterol, and simple carbohydrates at all times during active AAS administration. Supplementing with fish oils (4 grams per day) and a natural cholesterol/antioxidant formula such as Lipid Stabil or a product with comparable ingredients is also recommended.[/FONT]
[h=3]Side Effects (Testosterone Suppression):[/h][FONT=&quot]All anabolic/androgenic steroids when taken in doses sufficient to promote muscle gain are expected to suppress endogenous testosterone production. Stanozolol is no exception, and is noted for its strong influence on the hypothalamic-pituitary-testicular axis. Clinical studies giving 10 mg per day to healthy male subjects for 14 days caused the mean plasma testosterone level to fall by 55%.[SUP]625[/SUP] Without the intervention of testosterone-stimulating substances, testosterone levels should return to normal within 1-4 months of drug secession. Note that prolonged hypogonadotrophic hypogonadism can develop secondary to steroid abuse, necessitating medical intervention.[/FONT]
[FONT=&quot]The above side effects are not inclusive. For more detailed discussion of potential side effects, see the Steroid Side Effects section.[/FONT]
[h=3]Administration (General):[/h][FONT=&quot]Studies have shown that taking an oral anabolic steroid with food may decrease its bioavailability.[SUP]626[/SUP] This is caused by the fat-soluble nature of steroid hormones, which can allow some of the drug to dissolve with undigested dietary fat, reducing its absorption from the gastrointestinal tract. For maximum utilization, oral forms of stanozolol should be taken on an empty stomach.[/FONT]

For example, Winstrol from Zambon (Spain) was designed for human use, and uses a refined powder that will pass through a 27-gauge needle.
