Description:
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 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.
Dosage:
The most common version of formestane sold was in a topical gel form and it was dosed at 100-200mgs per application. Users would apply it onto clean, dry skin and rub in thoroughly; usually on the thighs or upper arms. It took 1 to 5 minutes to dry.
The injectable version for both breast cancer purposes and bodybuilders is 125mgs twice per week or 250mgs once per week. |
