Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder. 11β-Hydroxyandrostenedione (11β-OHA4), also known as 11β-hydroxyandrost-4-ene-3,17-dione, is an endogenous, naturally occurring steroid and androgen prohormone that is produced primarily, if not exclusively, in the adrenal glands. It is closely related to adrenosterone (11-ketoandrostenedione; 11-KA4), 11-ketotestosterone (11-KT), and 11-ketodihydrotestosterone (11-KDHT), which are also produced in the adrenal glands.

It can be used as a biomarker for guiding primary aldosteronism subtyping in adrenal vein sampling where blood samples are taken from both adrenal glands to compare the amount of hormone made by each gland. Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder

Chemical Properties Needles
Usage An antitumor drug. An aromatase inhibitor
Usage antineoplastic, aromatase inhibitor

Formestane Description:

A. 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. Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder

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. Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder
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. Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder

Formestane has poor oral bioavailability and as such is no longer popular as many orally active aromatase inhibitors have been identified. Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder

Formestane Applications:

1). Formestane has a very long active life on the order of 24-36 hours. You can get any sport supplement version capsules for around $40 US or less. This amount of $ 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. Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder


2). 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. Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder


3). Forma Stanzol decreases SHBG by 34% thus increasing androgen activity, which basically makes androgens/steroids in your systems MORE effective WITHOUT any increase in dosage. Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder

4). Forma Stanzol increases IGF-1 levels by a whopping 26%. Doing so creates the perfect anabolic muscle building environment on cycle, off cycle and during pct. Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder
Forma Stanzol decreases the number of progesterone receptors (inhibits the trenbolone and “deca-dick” type side effects and increases fat loss). Buy 11β-Hydroxyandrostenedione (11β-OHA4) powder
