Halotestin is a legendary steroid among power lifters and strength athletes. Many of the best steroid stacks contain Halotestin as a primary ingredient. The primary effects of Halotestin revolve around strength and aggression. Due to the strength and aggression promotion, this makes Halotestin a popular steroid among power lifter, strength athletes and fighters shortly before competition. A few weeks of use leading up to competition is very common, and the boost in strength can potentially be greater than any other anabolic steroid could provide.
