AromaTASE inhibitors...........
SERMs
These products either inhibit the aromitisation of testosterone to estrogen (Arimidex, Letrizole)
Or modulate certain estrogen receptors while leaving others intact (Clomid, Nolvadex)
Some AAS heavily convert to estrogen causing unwanted side effects---gynecomastia--- being the most prevalent
Estrogen is "the female" hormone......beware though that crashing estrogen levels too low can cause unwanted estra sides such as joint pain, loss of sex drive/erection, slow or moderate gains.....
AIs can also be used post-cycle to increase levels of free test by inhibiting aromitisation
