Halotest® Fluoxymesterone is an anabolic androgenic steroid, 17beta-hydroxysteroid, 11beta-hydroxysteroid, fluorinated steroid and 3-oxo-delta(4) steroid. It plays the role of an antitumor agent and anabolic agent. An anabolic steroid that has been used to treat male hypogonadism, delayed puberty in men, and to treat breast tumors in women. Fluoxymesterone is an androgen. The mechanism of action of fluoxymesterone is that it is an androgen receptor agonist.

Fluoxymesterone is a halogenated derivative of 17-alpha-methyltestosterone. Like testosterone, fluoxymesterone binds to and activates specific nuclear receptors, resulting in increased protein anabolism, decreased amino acid catabolism, and nitrogen, potassium, and phosphorus retention. This agent can also competitively inhibit prolactin receptors and estrogen receptors, thereby inhibiting the growth of hormone-dependent tumor lines. Fluoxymesterone is about five times more potent than methyltestosterone.

Fluoxymesterone is found only in individuals who have used or taken this drug. It is an anabolic steroid that has been used to treat male hypogonadism, delayed puberty in men, and to treat breast tumors in women. Fluoxymesterone is a synthetic androgenic anabolic steroid that is approximately 5 times more potent than natural methyltestosterone. Like testosterone and other androgenic hormones, fluoxymesterone binds to the androgen receptor. It causes nitrogen, sodium, potassium and phosphorus retention; increases protein anabolism; reduces the catabolism of amino acids and reduces the excretion of calcium in the urine. The antitumor activity of fluoxymesterone appears to be related to the reduction or competitive inhibition of prolactin receptors or estrogen receptors or production.
