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.
