Although it is a hormone that brings out male sexual traits, testosterone is found in both guys and girls. Steroids cause muscles to grow at a rapid pace, making them popular among athletes. Steroids are ILLEGAL to buy, sell or use without a doctor's prescription, and can permanently damage your body if abused. There are mainly two different types of steroids:
Corticosteroids do NOT build muscles. Instead, they are usually prescribed to reduce swelling.
