Description:
Formestane is currently one of the best legal anti-estrogens out there. It is classified as an irreversible arromatase inhibitor, meaning, it destroys the aromatase enzyme.
Formestane has a very long active life on the order of 24-36 hours. You can get any sport supplement version capsules for around $40 US or less. This amount of $ will usually last you about 3-4 weeks at a sufficient dosage of 200-400mg per day. I have found 200mg a day to be perfect for on cycle anti-estrogen usage and for post-cycle recovery of natural testosterone. Formestane has zero negative feedback (even though it is an androgen by definition) and serves to elevate natural testosterone as well as any anti-estrogen/anti-aromatase drug out there, next to clomid.
Another name for formestane is hydroxyandrostenedione. For those of you who don't already know, andostenedione is and always was a lousy physique supplement (or drug, whichever you like to call it). As wel all know, the even the prohormones are now illegal in the US (as of Jan 20th, 2005). Tell me how weird chemistry can be...regular androstenedione is highly aromatizable. It converts to estogen very, very readily. When it was legal and everyone was using some form of it, I heard of numerous cases of gyno from it. At the time it was legal and was an over the counter supplement.
