Femara (letrozole) is the third generation aromatase inhibitor of type II (non-steroidal). Clinically, it is used to treat postmenopausal women with estrogen receptor positive or unknown breast cancer.
In women with breast cancer, estrogen levels have been shown to decrease by 98% or more. However, its use and benefits are not limited to eliminating female estrogen.
For pre-competition bodybuilders, letrozole is almost a necessary condition for eliminating water retention, and can obtain the necessary tear appearance in today's bodybuilding world. However, in my experience, it only needs to be used in the last 4-6 weeks to eliminate excessive estrogen and water retention. With letrozole, I recommend staying away from any estrogen suppression for at least a month in an attempt to normalize the body.
