Description

Letrozole is also called Femara, it is an oral non-steroidal aromatase inhibitor for the treatment of hormonally-responsive breast cancer after surgery.Estrogen are produced by the conversion of androgens through the activity of the aromatase enzyme. Estrogen then bind to an estrogen receptor, which causes cells to divide.Femara prevents the aromatase from producing estrogen by competitive, reversible binding to the heme of its cytochrome P450 unit. The action is specific, and Femara does not reduce production of mineralo- or corticosteroids.

Application

Femara is a type II (non-steroidal) third generation aromatase inhibitor. Clinically it is used to treat postmenopausal women with either estrogen receptor positive or estrogen receptor unknown breast cancer. In women with breast cancer, it has been shown to reduce estrogen levels by 98% or more.However, it's use and benefits are not limited to eliminating estrogen in women.For pre-contest bodybuilders, Femara is almost a necessity to eliminate water retention and achieve the ripped look necessary to compete in today's bodybuilding world. However, in my experience, it is only necessary to be used for the last 4-6 weeks, to eliminate excess estrogen and water retention. After using Femara I recommend staying away from any estrogen suppression for at least a month to try to normalize the body.
