As a male hormone and anabolic hormones. Applications:It is used to treat low testosterone levels in males and breast cancer in females.Though the half-life of fluoxymesterone is about 9.2 hours. Fluoxymesterone (trade name Halotestin) is an anabolic steroid with strong androgenic properties that has been used in the treatment of male hypogonadism, delayed puberty in males, and in the treatment of breast neoplasms in women. It is approximately 5 times as potent as methyltestosterone. The antitumor activity of fluoxymesterone appears related to reduction or competitive inhibition of prolactin receptors or estrogen receptors or production. Stenox also known as Halotestin (fluoxymesterone), is a halogenated derivative of 17-alpha-methyltestosterone and has an extreme androgenic effect and a very slight anabolic effect. With this combination, a person can expect a great increase in muscle hardness and strength with no real gain in size or weight. Because of the very high androgenic effect, many athletes have reported high levels of aggression making their workouts extremely intense. Like many C-17 alpha alkylated steroids, fluoxymesterone has poor binding to the androgen receptor. Even so, its actions are mediated by the androgen receptor, most-likely due to its prolonged plasma half-life. Effects : Halotestin is used in men who do not make enough of a natural substance called testosterone Fluoxymesterone is similar to the natural testosterone produced by your body. Abnormal drug-seeking behavior is possible with Halotestin, and it is frequently misused for its muscle-enhancing effects. Halotestin also exerts its effects on strength and fat loss by both regulation of fatty acid oxidation in the liver and fast-twitch muscle mitochondria .
