What is Letrazole/Femara?
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. In fact, its potency is sometimes too much for some to handle when used for off label use. Letrozole first gained U.S. FDA approval in 1997 and would hit the market under the brand name Femara through Novartis. Although Femara is the dominating trade name of the AI, unlike most AI’s it is the only one generally known by its chemical name Letrozole far more commonly than its dominating brand name.
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.
Letrazole/Femara Bodybuilding Application:
1) The anti-estrogen action of Femara has been shown to be useful in pretreatment for termination of pregnancy, in combination with misoprostol. It can be used in place of mifepristone, which is expensive and unavailable in many countries.
2) Femara is sometimes used as a treatment for gynecomastia, although it is probably most effective at this if caught in an early stage (such as in users of anabolic steroids).
3) Femara has also been shown to delay the fusing of the growth plates in mice.When used in combination with growth hormone, Femara has been shown effective in one adolescent boy with a short stature.
