5. Usage: Letrozole is a powerful Aromatase Inhibitor that was developed to fight breast cancer. For athletes and bodybuilders, it is a drug used to combat the estrogenic side effects of anabolic steroids water-retention, acne and gynocomastia. It will also raise testosterone levels because of the lowered estrogen in the body. Side effects from Letrozole include a lowered sex drive and continuous use can lead to lowered lipid function and an impaired immune system. 

 
Description:
 

There are some concerns with using an aromatase inhibitor such as this during prolonged steroid treatment however. While it will effectively reduce estrogenic side effects, it will also block the beneficial properties of estrogen from becoming apparent (namely its effect on cholesterol values). Studies have clearly shown that when an aromatase inhibitor is used in conjunction with a steroid such as testosterone, suppression of HDL (good) cholesterol becomes much more pronounced.

Apparently estrogen plays a role in minimizing the negative impact of steroid use. Since the estrogen receptor antagonist Nolvadex does not display an anti-estrogenic effect on cholesterol values, it is the preferred from of estrogen maintenance for those concerned with cardiovascular health.

Femara has another principle drawback, namely the great price of this drug. Tablets can be quite costly with regular use, but it can ward off the side effects of strong androgens much better than Nolvadex and/or Proviron, making heavy cycles much more comfortable.

As the number of countries manufacturing this drug increases, we may be able to look forward to a reduction in price. Privately compounded versions of "liquid Femara have also been formulated "for research purposes" and are currently circulating the black market. Generic tabs are also available and these two forms represent a very cost-effective alternative for buying the brand name drug.

 
Applications:

For the steroid using male athlete, Femara shows great potential. Up to this point, drugs like Nolvadex and Proviron have been our weapons against excess estrogen. These drugs, especially in combination, do prove quite effective.

But Femara appears able to do the job much more efficiently, and with less hassle. Its use is only now catching on, but early reports have been excellent. A single tablet daily, the same dose use clinically, seems to be all one needs for an exceptional effect (some even report excellent results with only 1/4 tablet daily).
