Letrozole is currently the most powerful aromatase inhibitor
available.In the world of bodybuilding it is used to reduce or
eliminate excess estrogen caused by the use of aromatizing
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
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.
