Muscle Gain Fluoxymesterone Raw Testosterone Powder CAS 76-43-7

Fluoxymesterone is used to treat symptoms of low testosterone in adult men who have hypogonadism (a condition in which the body does not produce enough natural testosterone). Fluoxymesterone is used only for men with low testosterone levels caused by certain medical conditions, including disorders of the testicles, pituitary gland, (a small gland in the brain) or hypothalamus (a part of the brain) that cause hypogonadism. Fluoxymesterone is also used to stimulate puberty in men with delayed puberty. Fluoxymesterone may also be used alone or along with other medications in certain women with breast cancer that has spread to other parts of the body and can not be removed with surgery. Fluoxymesterone is in a class of medications called androgenic hormones. It works by supplying testosterone to replace the testosterone that is normally produced naturally in the body. Testosterone is a hormone produced by the body that contributes to the growth, development, and functioning of the male sexual organs and typical male characteristics. When used to treat breast cancer, testosterone works by blocking the release of estrogen to stop or slow the growth of breast cancer..

Fluoxymesterone comes as a tablet to take by mouth. It usually is taken with or without food once a day or three or four times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take fluoxymesterone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Continue to take fluoxymesterone even if you feel well. Do not stop taking fluoxymesterone without talking to your doctor.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
