Clomid at 25mgs ed is the very first step a patient "can" take when they approach an Endocrinologist. For instance I worked with Metabolic Dr. and that was one option. I have seen the average hypogonadal patient acheive about 600-1000 n/dL levels on that dosage. So you would be in a healthy, non superphysiological range.
HCG also can be used as HRT. Though it is suppressive.
As for AI's like Multi said, unless you "need" it, don't use one. On HRT, I would say the majority of patients I dealt with in the Medical field, did not need one "IF" they stayed on true HRT dosages. HRT dosages are not "cycles". This new generation thinks 500mgs of Test per week is HRT. That is a cycle.
What we found best was administering 100mgs of Test Cyp/E every 4th day. We also administered or O'Connor (Metabolic Dr) HCG at 250-500iu 2x per week. With the addition of the HCG you may indeed see a little bit more estrogen while on cycle.
Nevertheless if you do need an AI, on HRT, I personally have seen way to high of dosages. What I use with my guys and what I prefer is Exemestane, and we will start out as low as 6.25mgs e3d. You will see an increase in free testosterone when taking something like EXEM alongside your HRT dosages.
Also jump on some liver support. What alot of newbies or even AAS abusers don't realize, is that your body metabolizes Testosterone. Their is an indvidual response based on how "YOU" metabolze testosterone. The healthier your organs and liver, the more likely you are going to metabolize testosterone better. Guys with massive stress to their organs will then test their levels and blame the brand for being poor quality when many times it is because their body is so taxed it is metabolizing testosterone poorly.
This is what I use myself and with clients. I didn't come here intending to sell you something but I certainly will show you what it is I carry, use and sell.
Another tip I will give you is to rotate injection sites constantly. The body will absorb and do much better with fresh muscle tissue, then if you keep injecting into the same area. Oil can build up in that site and not only slow down absorption rates, but it can also form an abcess or pre-abcess.
Easiest place for a newbie are the glutes, shoulders and pecs. I personally do not suggest Quads bc the rate of Preabcess, lumps and pain is the highest of any injection area in my experiences with patients, clients and personally.
If you need a legit TRT option that will prescribe you an actual decent amount of Test and 100% legal you can uise my buddies place
