Pharmaceutical Name: Halotestex Chemical name: Fluoxymesterone Chem. Abstr. Name: 9a-fluoro-11b,17b-dihydroxy-17a-methyl-4-androsten-3-one Molecular Structure: C26H29NOC6H8O7 Molecular Weight: 336.4457 Product Description: Halotestex (fluoxymesterone) is an oral derivative of the male hormone testosterone. Unlike testosterone, halotestex does not convert to estrogen. Therefore, estrogen-related side effects such as fat deposition, water retention, and gynecomastia do not occur. Halotestex has powerful androgenic properties. It is particularly noted for increased strength without significant additional weight gain. Side effects include aggression, oily skin, and virilization. Halotestex is considered to be very toxic to the liver, and thus must be used with caution and for short durations only. Presentation: Tablets are pale pink coloured square with a score and the letters "BD" imprinted on one side and 10mg imprinted on the other side, sealed in foil pouches of 50 and 100.
