Though you may already be aware of potential side effects from testosterone abuse (note I said abuse and not use), here they are again: lowered HDL-cholesterol levels (good cholesterol), testicular atrophy, reductions in sperm count, prostate enlargement, liver damage (primarily with oral steroids that have been modified with a 17-alkyl substitution), menstrual irregularities, suppression of endogenous hormone levels (like LH and T), development of palpable breast tissue in men (also known as gynecomastia), clitoral enlargement, and acne.
Many bodybuilders use steroids to increase their muscle mass and to build a perfect body shape, during a steroid cycle the muscles have a fast growth, but at the end of the cycle a part of the muscles goes away. This consequence can not be stopped, but there is a way to reduce them and try to preserve a great part of your muscle mass. First we will talk about some processes that happen in the body system during the steroids cycle, this is about: hormone levels, recovery process is faster after the training sessions, nutrients are being faster processed by the body.
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.
