Finding a estrogen inhibitor that works best for you can be tricky but it is very key. Some cycles won't require as "dense" of a compound AI (Aromatase inhibitor) as others. Although the harsh effects of using AI compounds is far less to mainly inexistent for most in comparison to the 'enhancing compound' side of the spectrum, but things such as cost and availability come into play.
The majority of AIs come in three forms, pill/tabs, liquid, and external trans-dermal (rub in lotion type). I have had very successful cycles of testosterone, tren and orals (Anavar/whinny) all combined using a OTC trans-dermal (forma-stanzol) as suggested of direction of use. But it took very close monitoring of my symptoms of elevated estrogen levels. Truth be told some days I could really tell that my estrogen was spiking in comparison to others, with overt fatigue and moodiness being the main key tell points. And with that being said it was not the proper AI to use for such a cycle, but all and all I got by with it, but it could of been a smoother ride.
*Keep in mind my I don't get harsh side effects of high estrogen levels or gyno. In fact my E levels have always been fairly simple to maintain. Years back, my first cycle was a complete waste because I had no clue what a AI was and ran just test at 600mg a week starting and even bumped it up to 900mg a week thinking I wasn't feeling it. Well the lack of knowledge at the time didn't help for when i had a huge decrease in energy, strength and even libido. 12 weeks later of trying to just push test in my system I figured out through research that I probably had extreme levels of estrogen being built up. Lesson learned! Every cycle after that became easier and easier to read and listen to my bodies signals. That plus understanding the importance of blood testing to give a actual display of what is going on inside the body just in a read out of numbers.
Trans-dermals should be kept for short simple and maybe even oral only cycles in my option. Back when Pro Hormones were legal (which btw there is very little reason to use a PH now considering the legality, you might as well just use a full on oral such as dbol or Tbol. *but when PH was a otc substance worth using it was my #1 recommendation for anyone starting off in the AAS world). Also trans-dermals are also great for pct when needed.
There are several different pharmaceutical grade AIs available for use and widely used in body building. Arimidex (anastrozole), Aromasin (exemestane), Telsac (testlactone), Famara (letrozole) to name the most common. Each have their own place and some work better for people then others. For instance I prefer and use anastrozole. It just works best for me. It's slightly less mild then the rest and it is normally all I need. My go to cycle is 100mg testosterone prop, and 100mg tren ace and I take 1mg tab of anastrozole every other day. It suits me.
Now many things throw the body off, such as diet (certainly known during a cutting phase or cycle on a low caloric deficit), or mass amounts of food during a bulk. Also sleep contributes to the way that the levels respond. So if I feel a major drop in hormones, the tell tale signs of my levels being off (that being estrogen because it's what my body is forced to produce, as I am synthetically regulating my testosterone intake. Remember one balances out the other, or so we hope). I may take a small dosage of letrozole, a much harsher compound with the determined effects that are much greater, for a day or two, to even back out when extremes are needed. Simple checks and balances control system I use.
Some people swear by aromasin, it probably works best for them. Like I explained I find anastrozole to be the better choice for me.
What is your go to AI and why did you choose it?
For people struggling to find the right AIs the info can be of great help deciding.
