There are two classes of Anabolic Steroids 1. Anabolic Androgenic Steroids 2. Anabolic androgenic steroids are artificial versions of testosterone, the hormone that is responsible for making most males generally larger, stronger and hairier than females. It is also the reason why males in general have deeper voices than females.
Some athletes believe that anabolic steroids increase lean muscle mass, strength and endurance.
Scientific evidence, however, has shown that anabolic steroids only enhance physical performance due to some of their effects that assist with training and motivation, for example, euphoria, and aggression, lessening of fatigue and quicker recovery time. There can be serious side effects associated with the use of anabolic steroids. Not all people will experience these side effects to the same degree. As with any drug, people react differently. It is therefore impossible to say exactly what will happen to a person who uses anabolic steroids.
