Mike told the author about his friend who started using anabolic steroids and experienced dangerous mood swings and aggression as a result. His friend threw weights across the gym during a fit of rage nearly injuring Mike. Mike no longer feels safe around his friend who is no longer the same person. While steroids can have psychological effects like increased aggression, following proper dosage guidelines and avoiding "stacking" multiple drugs may help reduce these risks, but friends and family should still be cautious of abnormal behavior in users. The author recommends seeking help for users experiencing extreme psychological issues before serious harm occurs.
