Halotestin is a very powerful oral anabolic steroid that was first described in 1956. Its androgenic properties are five times more than that of methyltestosterone, but its anabolic effects are considered moderate in comparison. This makes it a very popular drug where strength increases are required. Halotestin is not the ideal drug where muscle gain is required though, however it’s still very popular amongst competitive bodybuilders due to its inability to aromatase into estrogen. This suggests that typical estrogenic side-effects like water-retention and gynocomastia should not be a concern when using this drug. The lack of bloating combined with the increases in muscle density makes this the perfect drug to enhance muscle definition during pre-contest cycles.

Halotestin is also used by athletes where minimal weight gain and maximum performance is sought after. For example; boxers, weight lifters, power lifters and wrestlers. Many athletes in these explosive strength sports even specifically favor highly androgenic drugs such as fluoxymesterone due to their perceived greater abilities to support aggression and the competitive drive. Even though Halotestin exhibits no estrogenic side-effects, androgenic side-effects are still very common with this substance, and may include bouts of oily skin, acne, body/facial hair growth, hair loss and aggression. Liver toxicity is also of great concern and Halotestin is likely one of the most toxic oral steroids when compared mg for mg against others like Anapolon or Winstrol. The use of liver support supplements is highly recommended.

An effective oral daily dosage would fall in the range of 10 to 40mg taken in cycles lasting no more than 6 to 8 weeks to minimize hepatotoxicity. This level is sufficient for measurable increases in muscle strength, which may be accompanied by modest increases in lean muscle mass. It not recommended for female athletes, because virilizing effects have been noticed on low dosages of 10 to 15mg.
