In the world of professional sports, particularly bodybuilding and strength athletics, Letrozole or Femara is an admired name. This wonder drug is second to none when it comes to the treatment of infertility for inducing ovulation.
Letrozole, which is also known as Femara, is used in the world of anabolic steroids and performance enhancing drugs as a powerful antiestrogen. In the world of healthcare, it is used to treat spread of breast cancer after standard options of treatment such as Tamoxifen therapy have failed.
The chemical name of Letrozole is 4,4′-(1H-1,2,4Triazol-1-ylmethylene)dibenzonitrile and its molecular formula is C17H11N 5. This drug has the molecular weight of 285.31 g/mol at the base.
Sportsmen, especially steroid users, prefer Letrozole over other antiestrogens as it can inhibit the formation of estrogens by as much as 98 percent. In addition to that, Letrozole can enhance the levels of follicle-stimulating hormone, luteinizing hormone, and sex hormone-binding globulin significantly. Moreover, steroid users can easily avoid steroid side effects such as oily skin, acne, gynecomastia, and water retention by using Letrozole.
The recommended dose of Letrozole (Femara) is 2.5 mg per day and this antiestrogen is best taken at the end of a steroid cycle. It is important to note that this antiestrogen is not recommended for pregnant and breastfeeding women or those using heavy machinery or performing activities requiring complete attention as its use can lead to dizziness. In order to maintain its shelf life, Letrozole is best stored at a controlled temperature of 25°C (77°F) with excursions permitted up to 15-30°C (59-86°F).
