Femara is primarily used to ward any estrogenic side effects caused by the administration of anabolic steroids. This steroid has been show to have the capability of reducing the level of estrogen in users’ bodies by up to 96-98%. This would seemingly be enough in itself to make the compound a desirable one with which steroid users would be interested in.
However Femara also has been shown to increase the amount of lutenizing hormone, follicle stimulating hormone, and sex hormone binding globulin in users. When you combine these attributes with the fact that it will help protect against gynocomastia, water retention and other estrogenic side effects letrozole obviously can fulfill many users needs.
