The drugs modify the chemistry in your brain, production of dopamine, serotonin, which make your mood. It is all artificial. Once you get off the drugs, all the artificial effects disapear and you get back to your normal mood. The psychological problems you might have even if hidden, arent solved. Why can t you live without drugs that artificially modify your perception of reality? Why cant you feel good without drugs?
You re going to get addicted to the feeling of artificial well beingness produced by the drugs and wont be able to go off them.
American Medical Association at the hearings leading to the Steroid Control Act of 1990 stated there was no evidence anabolic steroids had any effect on mental addiction, nor did they alter the mental state of an individual in anyway comparable to controlled narcotics, and based on this evidence, or lack thereof stated "we vehemently oppose the ban."
