Application

Formesta 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.Formesta 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.

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

Formesta decreases SHBG by 34% thus increasing androgen activity, which basically makes androgens/steroids in your systems MORE effective WITHOUT any increase in dosage.

Formesta increases IGF-1 levels by a whopping 26%.Doing so creates the perfect anabolic muscle building environment on cycle, off cycle and during pct.

What is the Formesta ?

Formesta is currently one of the best legal anti-estrogens out there.It is classified as an irreversible arromatase inhibitor, sens, it destroys the aromatase enzyme.

Formesta is a synthetic steroidal substance with antineoplastic activity.Formest 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.

Formest 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.Formesta is currently one of the best legal anti-estrogens out there.It is classified as an irreversible arromatase inhibitor, sens, it destroys the aromatase enzyme.

Formesta (Lentaron) inhibiteur de l'aromatase stéroïdienne. Il est utilisé dans le traitement du cancer du sein à récepteurs œstrogènes positifs chez les femmes ménopausées.. Il est disponible sous forme d’injection intramusculaire retard.

Formesta is often used to suppress estrogen production from anabolic steroids or prohormones. Il agit également comme une prohormone de la 4-hydroxytestostérone., an active steroid which displays weak androgenic activity in addition to acting as mild aromatase inhibitor.

Formesta has poor oral bioavailability and as such is no longer popular as many orally active aromatase inhibitors have been identified.
