These legal substances consist of “scientific diets, oxygen tents, and supplements that tune up athletes' bodies,” underscoring the fact that advocates believe athletes are already technically cheating (Murray). Enthusiasts believe that athletes are already helped by the advanced technologies seen in the world of sports, so the incorporation of steroids would not allow them to see a substantial difference.
