Fluoxymesterone is an oral anabolic steroid which is a derivative of the hormone testosterone. Specifically, it is a methyltestosterone derivative, being different due to the addition of 11-beta-hydroxy and 9-alpha-fluoro groups. The result is a very potent orally active non aromatizable steroid that shows extremely potent androgenic properties. Fluoxymesterone is considerably more androgenic than testosterone, while the anabolic effects of this drug are considered to be moderate in comparison. Fluoxymesterone was first developed in the 1950’s. It was introduced to the US pharmaceutical market shortly after and first marketed by the company UpJohn. It was prescribed for the purposes of tissue repair, burns, delayed healing of fractures, and for males with insufficient androgen levels. Users of Fluoxymesterone often report great gains in strength and muscle hardness, while not noting much in terms of actual tissue growth and bodyweight increase. Because of this, this steroid is very popular amongst powerlifters and other athletes who wish to increase performance while not adding much weight to keep them in a certain weight class. This drug is also a favorite of bodybuilders in the final weeks before a show. Halotestin is generally considered a specialty steroid in the sense that it’s not widely used in the common cycles that most novice users are accustomed to. Users of halo might wish to stack it onto a bulking cycle such as testosterone and deca in order to add a little more androgen into the mix and increase strength gains seen significantly. Those looking to cut will often add halo to other compounds such as trenbolone. Fluoxymesterone is a C17aa oral which means that it can be hepatoxic on the liver and because of this, users are strongly urged to limit cycles to 4-8 weeks and to keep dosages of halo within a reasonable range. It is also recommended that users run a liver protectant such as Liv-52 or milk thristle during administration of a C17aa such as Fluoxymesterone. Being the strong androgen that it is, users often experience androgenic side effects when running this compound. These side effects can include things such as oily skin, acne, and increased body and facial hair. Fluoxymesterone does not convert to estrogen and therefore estrogenic side effects shouldn’t be a concerned when running this compound. Halo will shut down the body’s ability to produce testosterone naturally. Because of this, users will want to run a post cycle therapy protocol consisting of products such as clomid and HCG upon discontinuance of use of this compound. Men usually take Fluoxymesterone in a dosage of 20-40mg a day for a period of 4-8 weeks depending on what the goals of usage are. Users are encouraged to take Fluoxymesterone on an empty stomach because food may decrease its bioavailability. Women should stay away from this substance as the strong androgenic properties are sure to cause masculizing side effects which made include deepening of the voice, clitoral enlargement, and the growth of facial hair.
