Formestanes (Lentaron) is a type I, steroidal aromatose inhibitor. It is used in the treatment of estrogen-receptor positive breast cancer in post-menopausal women.

Formestanes is often used to suppress estrogen production from 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.

Formestanes Features Include:
-Increases in IGF-1
-Lowers SHBG to make anabolic hormones more active and in a free state
-Increase natural Testosterone to above normal human levels and continues to work even after use has stopped.

– Lowers and Controls Estrogen and prevents the negative side effects associated with Estrogen
– Prevents Estrogen Rebound because it is a Type I aromatase Inhibitor similar to Aromasin (Exemestanes)
– Prevents conversion of Testosterone to DHT meaning it can help prevent hair loss in some cases as well as prostate issues.
