1. Letrozole is a powerful Aromatase Inhibitor that was developed to fight breast cancer.

2. For athletes and bodybuilders, it is a drug used to combat the estrogenic side effects of anabolic steroids water-retention, acne and gynocomastia.

3. It will also raise testosterone levels because of the lowered estrogen in the body.

Femara (letrozole) 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 (1). However, it’s use and benefits are not limited to eliminating estrogen in women.

For pre-contest bodybuilders, Letrozole 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 Letrozole I recommend staying away from any estrogen suppression for at least a month to try to normalize the body

Female Letrozole Dosage

Letrozole doses of 1.25mg every other day or once every two days should suffice and in fact often times become too much, in which case the individual might feel the need to adjust to either a lower dose or a lesser frequency of administration.
