Halotestin is a unique PED that is not really cycled12. It is best used as a pre-competition or pre-workout in the days leading up to a power competition or duel12. The typical cycling duration is 2-4 weeks3. The dose for a primary or intermediate cycle is 10-20 mg/day for 4 to 6 weeks, while for a more advanced cycle, the dose is 30-40 mg/day for 6 to 8 weeks4. Some bodybuilders take 20mg of Halotestin (per day) for 2-3 weeks, before completing their final week on a higher dosage of 40mg per day5.
