When young boys are getting conscious about how they look, some of them usually find an easy way - anabolic steroids. These are synthetic substances that are the same as testosterone (male hormone). They have legal uses. Doctors even prescribe them for anemia and for those who lacks testosterone. However, they don't recommend such steroids for building of muscles. Out in the street, steroids are called juice or roids. Scientifically, they are anabolic-androgenic. Anabolic means muscle-building, while androgenic is the increase of male natural qualities. They are taken as pills or through the use of needles.
