99.2% Safe & Effective Anti-Estrogen Letrozole / Femara Powder Pharmaceutical Grade
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.
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.
