Effects :

In one male test subject Letrozole was able to reduce estrogen levels to undetectable levels
Letrozole is able to raise test in male subjects.

Usage :

Using Letrozole at such a low dose does happen to make it a very good economic choice compared with other aromatase inhibitors.

Letrozole has a 2-4 day half-life, and it needs to be taken for up to 60 days to get a steady blood plasma level .

Applications:

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.
