Femara General Info

Femara is a third-generation aromatase inhibitor with a non-steroidal structure. Femara is the newest and the most potent aromatase inhibitor on the market. FDA approves Femara, and it is widely used worldwide to treat postmenopausal women with breast cancer. In most cases, it is prescribed if the treatment with Nolvadex was not successful.

Femara in Sports

Male athletes and bodybuilders use Aromasin to prevent estrogenic side effects such as gynecomastia, water retention, fat build-up. Femara is considered one of the strongest Ai available on the market. Clinical trials showed that a modest dosage of 0.5 mg produced an astonishing 78% estrogen inhibition.
Please note
Some compounds do not convert to estrogen however have a high level of estrogenic activity. An excellent example of such compound is Oxymetholone. Anti-aromatase compounds Arimidex, Femara, or Aromasin, will not be effective. To avoid the estrogenic side effects, we recommend using anti-estrogens such as Nolvadex and Clomid.

Steroid Lethargy or Crushed Estrogen
Estrogen plays a vital role in promoting an anabolic state in muscle tissue and the production of growth hormones. Also, it was demonstrated that estrogen increases the concentration of androgen receptors and plays a crucial role in promoting wakefulness. An extreme estrogen suppression might lead to fatigue, also called "steroid lethargy."
