Fluoxymesterone is a synthetic anabolic-androgenic steroid primarily used in the treatment of conditions related to low testosterone levels in men, such as delayed puberty or certain types of impotence. It helps in promoting the development of male characteristics like increased muscle mass, facial hair growth, and a deeper voice. Additionally, it is sometimes prescribed to treat breast cancer in women, particularly in cases where the cancer has metastasized. The drug works by mimicking the effects of natural testosterone, thereby aiding in the management of these medical conditions. It is important to use this medication under strict medical supervision due to its potent hormonal effects and potential side effects, including high blood pressure, liver problems, and mood changes.
