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 a white or nearly white, odorless, crystalline powder, melting at or about 240ºC, with some decomposition. It is practically insoluble in water, sparingly soluble in alcohol, and slightly soluble in chloroform.
The chemical name for fluoxymesterone is androst-4-en-3-one, 9-fluoro-11,17- dihydroxy-17-methyl-, (11β,17β)-. The molecular formula is C20H29FO3 and the molecular weight 336.45.

Functions of Fluoxymesterone Halotestin
Fluoxymesterone is used to treat a deficiency of the male hormone testosterone when the body does not make enough. It is also used to stimulate puberty in males with delayed puberty. Treating advanced breast cancer in women who are 1 to 5 years past menopause. Fluoxymesterone is an androgen. It works by stimulating normal growth and development of the male sex organs and maintaining normal secondary sex characteristics.

Dosages of Fluoxymesterone Halotestin
Dosage of halo should never exceed 40mg a day or you are going into the danger zone of abusing this steroid. It should also never exceed 5-6 weeks and to be honest 4 weeks might be a smarter cap because this is a steroid that you might get tired of using, no pun intended. Some lifters like to take 10mg before their workout for an added boost and spread out the rest of their dosage during the day. Since halo has a short half life (6-8hours) this strategy has merit. I personally when I am focusing on strength during the year will run 20-30mgs a day total, and take 10-20mgs 2 hours before my strength workout for an added punch.
