Usage An antitumor drug. An aromatase inhibitor 

Description: 
A. Formestanes is a synthetic steroidal substance with antineoplastic activity. Formestanes binds irreversibly to and inhibits the enzyme aromatase, thereby blocking the conversion of cholesterol to pregnenolone and the peripheral aromatization of androgenic precursors into estrogens.
 
B. Formestanes 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. Formestanes 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.
 
C. Formestanes is often used to suppress estrogen production from anabolic steroids or prohormones. It also acts as a prohormone, an active steroid which displays weak androgenic activity in addition to acting as a mild aromatase inhibitor.
Formestanes has poor oral bioavailability and as such is no longer popular as many orally active aromatase inhibitors have been identified.
