Basically, Letrozole is a drug that was developed to fight against breast cancer by aromatization inhibition. It is usually used as part of aggressive treatment in post-menopausal women, to fight and reverse the spread of breast cancer after other treatments have failed (such as tamoxifen therapy). It is probably the most effective product on the market for this purpose currently, it is very similar in structure and action to its predecessor arimidex.
Letrozole is also and above all of particular interest to bodybuilders and athletes. First of all, proven to reduce estrogen levels by 98% or more. This is obviously of huge interest to bodybuilders. In effect, less estrogen in the body eliminates side effects of steroids such as water retention, gynecomastia, and acne. This makes Femera one of the best anti-estrogens on the market, even for very difficult cycles. Also, if you are doing bodybuilding competitions the Femera helps to have a lean and striated muscle. The effective dose for Femera is 2.5 to 5mg per day. If you exceed this dose, there may be a risk of loss of libido. Also if you keep your estrogen levels too low for too long you will end up weakening your immune system.
Dosage: Take 1 or 2 tablets of 2.5 mg per day during or after cycle.
