Letrozole (Femara)

Letrozole (Femara) is the second in a new class of third-generation selective oral aromatase inhibitors. It acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen.

Letrozole appears to be a great new weapon in the arsenal to combat excess estrogen production. Until now we have had drugs like Clomid, Nolvadex and Proviron which all did a good job eliminating estrogen an estrogenic side effects. Letrozole eliminates estrogen through a different mechanism and does so very effectively. In studies just 2.5mg daily eliminated over 80% of estrogen in users. Early reports from the bodybuilding community have been excellent. Users report that doses as low as 0.5mg daily can be effective in eliminating the side effects from aromitizing steroids such as testosterone and Dianabol. Even with these small doses of letrozole it appears that gynocomastia and water retention are blocked. Using letrozole in small doses like this while “on” appears to give better muscle quality. Muscles appear harder and more defined with minimal water retention.

There are some negatives associated with the use of Letrozole. A strong aromatase inhibitor such as letrozole will also block the benefits of estrogen in our bodies. Namely this is estrogens effect on cholesterol values. Studies have shown that estrogen is beneficial for HDL (good) cholesterol values. By eliminating estrogen so completely we see a negative impact on cholesterol values as well. Weaker compounds such as SERM’s and ATD do not effect cholesterol negatively so they are preferred for those concerned with cardiovascular health.

A second negative effect of letrozole is that it will kill your libido. Estrogen plays a part in libido even for men. By eliminating estrogen in your body you also eliminate your libido. This effect can become apparent in as little as 4-5 days with some users.

Finally, letrozole is expensive compared to Nolvadex and Clomid. It can be quite expensive for regular use, but since it gets rid of the side effects associated with strong aromatizing steroids so well it will make a cycle more comfortable. There are generic versions of letrozole available as well as privately compounded liquid letrozole sold as research chemicals that can provide a cost effective alternative to the brand name Femara.
