Pro-hormones are compounds that are converted into anabolic hormones by the body. They are similar to steroids in terms of fat loss and muscle building effects. Some Pro-hormones have the ability to increase sex drive, reduce body fat and in order to boost intensity levels. They can be divided into the following categories – the andro group, the testosterone group and the 19-nor group. The 19-nors are converted into anabolic compounds and the andro group is converted into natural hormones by the body. The third compound group does not convert to nandrolone or testosterone rather they stimulate the body to increase the generation of the male hormone naturally for muscle building and fat loss.

Bodybuilding manufacturers have been supporting a “Pro-hormone” war in order to lure the consumers to their own particular brand. The scientific proof of the effects of these supplements is mixed. Some studies show no benefits of using these while other show that muscle size and strength increase due to increase in testosterone levels. Until the arrival of the anabolic steroid control act pro-hormones were the legal form of steroids which were later classified as classified drugs.
