According to this anonymous professional, no health problems exist in any of the Mr. Olympia (largest annual and most competitive bodybuilding competition in the world) today. Just recently, Mike Matarazzo sustained a serious shoulder injury and Fukes (both well-known professional bodybuilders) blew out both of his knees but neither were from the use of steroids. I know of no ex-pro bodybuilders that are having health problems as a result of using steroids. The media (and government) will tell you all kinds of horror stories, but conveniently leave out the fact that the people having health problems were also mind-altering drug users.
If you do not know what you are doing (. you used steroids with the most side effects, you abused the dosage, etc) then not only will you get bad side effects during the period of use, but you also will also get worst side effects after the use. Again, the degree of side effects is directly proportional to the dosage and type of the steroid and also dependent of the genetic propensity of the subject to get such side effects. Therefore, it would be impossible for me or anyone else to exactly predict what kind of side effects a user might encounter during a period of use. However, one thing is for certain. If you abused the drugs by using super high dosages and for very long periods of time, you may never be able to re-establish natural testosterone production, so you will then need to get with an endocrinologist and possibly stay on low dose testosterone therapy for life.
