Letrozole works by lowering overall estrogen levels in the body. It blocks the aromatase enzymes that neutralize a wider range of estrogenic side effects caused by anabolic steroids. It is one of the most popular estrogen-control drugs for steroid users. It also helps prevent users from the high blood pressure that accompanies excessive water retention.
Athletes use aromatase inhibitors like Letrozole to prevent various estrogenic side effects such as gynecomastia, water retention and bloating. In addition, Letrozole lowers estrogen levels and stimulates the body’s natural production of testosterone. Thus, steroid users mainly use Letrozole during steroid treatment and post-cure therapy medication.
