UN. Formestane is a synthetic steroidal substance with antineoplastic activity. Formestane 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. 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.
C. 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.
Formestane is a lot like arimidex in its mechanism of action in attacking the aromatase enzyme itself. Formestane attacks the aromatase enzyme and is therefore a first line inhibitor.So if you need immediate relief of estrogen during your cycle, you need a second class drug (estrogen receptor blocker) such as nolvadex or clomid.
Formestane decreases SHBG by 34% thus increasing androgen activity, which basically makes androgens/steroids in your systems MORE effective WITHOUT any increase in dosage.
Formestane increases IGF-1 levels by a whopping 26%.Doing so creates the perfect anabolic muscle building environment on cycle, off cycle and during pct.
