dscription:
Formestane (Lentaron) is a type I, steroidal aromatase inhibitor.It is used in the treatment of estrogen-receptor positive breast cancer in post-menopausal women.It is available as an intramuscular depot injection.
Formestane is often used to suppress estrogen production from anabolic steroids or prohormones.It also acts as 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 currently one of the best legal anti-estrogens out there.It is classified as an irreversible arromatase inhibitor, meaning, it destroys the aromatase enzyme.

Application :
Formestane has a very long active life on the order of 24-36 hours.This amount 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.

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 is a lot like arimidex in its mechanism of action in attacking the aromatase enzyme itself.

Formestanedecreases 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.
