Letrozole Usage/Application:
1. Letrozol is a powerful Aromatase Inhibitor that was developed to fight breast cancer.
2. For athletes and bodybuilders, it is a drug used to combat the estrogenic side effects of anabolic steroids water-retention, acne and gynocomastia.
3. It will also raise testosterone levels because of the lowered estrogen in the body.
4. Femara(generic name is letrozol) is a new drug developed for the treatment of advanced breast cancer in women.
5. Femara is the second in a new class of third-generation selective oral aromatase inhibitors.
6. It acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen.
Aplicaciones:
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). sin embargo, 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. sin embargo, in my experience, it is only necessary to be used for the last 4-6 semanas, 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.

Effects of Letrozole:
AI’s like Letrozole are the most effect means at combating estrogenic related side effects. sin embargo, they can also have a negative impact on cholesterol. Alone AI’s do not appear to have a strong, negative effect on cholesterol, but when coupled with an aromatizing steroid like testosterone the adverse cholesterol effect is enhanced. For this reason, many will find SERM’s like Tamoxifen Citrate (Nolvadex) should be their first choice in estrogen protection. SERM’s will not negatively affect cholesterol; in fact, SERM’s, while anti-estrogenic, actively act as estrogens in the liver, and in turn, promote healthier cholesterol levels. We’ll look at this in more detail in the side effect section, and while Letrozole can be used without an adverse cholesterol effect, it will take some effort on your part.
