HALOTESTIN

Fluoxymesterone is a halogenated derivative of 17-alpha-methyltestosterone.
Similar to testosterone, fluoxymesterone binds to and activates specific nuclear receptors, resulting in an increase in protein anabolism, a decrease in amino acid catabolism, and retention of nitrogen, potassium, and phosphorus. This agent also may competitively inhibit prolactin receptors and estrogen receptors, thereby inhibiting the growth of hormone-dependent tumor lines. Fluoxymesterone is approximately five times more potent than methyltestosterone.
Fluoxymesterone is an anabolic androgenic steroid, a 17beta-hydroxy steroid, an 11beta-hydroxy steroid, a fluorinated steroid and a 3-oxo-Delta(4) steroid. It has a role as an antineoplastic agent and an anabolic agent.
