Letrozole Description

Letrozole is an anti-estrogen of the Aromatase Inhibitor (AI) family and is one of the most potent and powerfully effective of all AI’s.

Letrozole was first developed in an effort to combat breast cancer in post-menopausal women. In fact, it would prove to be virtually identical to the already popular AI in Arimidex (Anastrozole). While intended for breast cancer treatment, like many AI’s, it has found a welcomed home among anabolic steroid users. Letrozole is one of the most commonly used anti-estrogens among steroid users during steroid use to combat possible estrogenic related side effects. It is so effective as an anti-estrogen in this regard many anabolic steroids have effectively reversed gynecomastia symptoms with Letrozole.

Letrozole cycle or dose reviews:

For the anabolic steroid user, Letrozole doses will normally be much lower. Even with the use of anabolic steroids, a 2.5mg dosing will normally be too high and could potentially drain the individual of energy. Most men will find 0.5-1mg every other day to be more than enough. When used as an anti-estrogen in low testosterone treatment plans, even less may be needed. For the competitive bodybuilder, the final 7-14 days before competition, a full 1mg per day leading up to the show can be a solid dose and will greatly help with dryness and a tighter look.

Letrozoles 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, using Letrozolesat such a low dose does happen to make it a very good economic choice compared with other aromatase inhibitors.
