Usage:Steroidal aromatase inhibitor.Formestane is often used to suppress estrogen production from anabolic steriods or prohormones.Formestane also acts as a prohormone to 4-hydroxyTest, an active steriod which displays weak androgenic activity in addition to acting as a mild aromatase inhibitor. Formestane has zero negative feedback (even though it is an androgen by definition) and serves to elevate natural Test as well as any anti-estrogen/anti-aromatase drug out there, next to clomid.

Product description:

Formestane is a drug that has been previously used in breast cancer treatment. Like most drugs which have some sort of phsyique usage, athletes eventually get a hold of it. 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.

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.


Applications:

Formestane is often used to suppress estrogen production from anabolic steroids or prohormones. It also acts as a prohormone to 4-hydroxytestosterone, an active steroid which displays weak androgenic activity in addition to acting as a mild aromatase inhibitor.Formestane has poor oral bioavailability and as such is no longer popular as many orally active aromatase inhibitors have been identified.
