2.Product Description:

 

Letrozole is approved by the United States Food and Drug Administration (FDA) for the treatment of local or metastatic breast cancer that is hormone receptor positive or has an unknown receptor status in postmenopausal women.Letrozole is intended for use only by women who are no longer of childbearing age. Possible candidates must have already ceased to menstruate. It is often used in patients who have already undergone other cancer treatments, such as radiation, chemotherapy, and used other cancer drugs, like tamoxifen. This nonsteroidal aromatase inhibitor may help prevent any remaining cancer cells from spreading.

 

3.Product Applications:

 

Femara 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). However, its use and benefits are not limited to eliminating estrogen in women.

For pre-contest bodybuilders, Femara is almost a necessity to eliminate water retention and achieve the ripped look necessary to compete in todays bodybuilding world. However, in my experience, it is only necessary to be used for the last 4-6 weeks, to eliminate excess estrogen and water retention. After using Letrozol I recommend staying away from any estrogen suppression for at least a month to try to normalize the body.
