To strengthen the anabolic properties of testosterone, more than 100 synthetic steroid derivatives have been described for human purposes. The anabolic effect promotes protein synthesis, muscle growth and erythropoiesis. In clinical practice, substances with anabolic effect are needed to overcome various catabolic states. However, none of these compounds are devoid of androgenicity. Androgenic and anabolic properties of anabolic steroids cannot be totally separated. Therefore, it is more appropriate to use the term anabolic androgenic steroids (AAS).
Bodybuilders take anabolic hormones in large quantities and often combine several different substances. But large doses are not made permanent. Roids use lasts from 4 to 18 weeks, then it’s stopped for a period of 1 to 12 months. This is called a "cycle". The combination this drugs and cycles vary greatly, depending on the hormones that are used and those who use it. All information about such products use is transmitted mainly by word from one juice user to another. Doses, which are now used by young bodybuilders are at least 36% higher than the doses used in the past. There is no official research being made in this area nowadays and nobody knows exactly how and what doses is better to use. Anabolics are mostly bought online. This encourage a lot of people to sell fake steroids online.
