For example human growth hormones have a positive effect in which they increase healing rate, strengthen the muscle fibers of the users and increase mental concentration (Tillery). Human growth hormones are naturally made by the body in the pituitary gland, but as you get older your body produces less and less of it (Tillery). Older athletes can use these growth hormones to bounce back faster from injuries so they can continue to participate in their sport. They need to be able to perform up to critique even when they are healing from injury so that they can get resigned for their contracts. There was an endocrinologist in Boston that was able to successfully inject human growth hormones into a young boy who had a growth disorder (Tillery). Since the growth hormones are made naturally in the body, the endocrinologist extracted them from a corpse which caused a limited supply of it. There are drugs out there that do cause damage and harm to the human body that overall should be banned, but the drugs that do not cause these health risks should be legalized for access to athletes. (Mounk). Indeed there are unknown substances out there that are being used by athletes so they can pass specific steroid tests, so if we allow them to use the enhancers that are safe, then there will be much less use of the unknown drugs that could be potentially dangerous. there was a study on how the anabolic steroids and corticosteroids affected the muscle contusions on rats. They resulted that corticosteroids have good short term effect, but leave long term injuries The anabolic steroids on the other hand were able to heal the contusion injury to speed the recovery of force-generating capacity (“The Effects of Anabolic Steroids”). Overall there are many positive health effects of performance enhancers such as steroids that can help with chronic diseases. According to Mark Lemouse, an author for the
