    Product Description:
    A. 4-Hydroxy Testosteroneis 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.4-Hydroxy Testosteroneis 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. 4-Hydroxy Testosterone 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.

    Applications:
    4-Hydroxy Testosterone 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.
