Teens and Steroids- “One thing that is not up for debate, that is a definitive fact, is that using steroids at a young age can cause premature fusing of growth plates – leading to stunted growth. There are many emotional and physiological factors that come into play while using steroids; needless to say the premature use of steroids by the young is a very bad idea.”
