Tragically, too many steroid users are guilty of just those crimes, and worse. As both a psychiatrist and a steroid expert, Dr. Pope has consulted in numerous criminal cases in which normally peaceful men, with no history of psychiatric problems, have suddenly gone berserk after a few cycles of steroids. In one case, a frail and timid 14-year-old boy began taking steroids to bulk up. He started having fits of anger so extreme that his mother took him to the emergency room to be examined. Two years later, at age 16, he stabbed his 14-year-old girlfriend to death with a carving knife while on a cycle of steroids.
