They are very easy for an athlete to obtain supplements. They are sold almost everywhere. In supermarkets, nutritional supplement stores, food stores, in magazines, and over the internet. They use them to develop their performance and appearance. They may also use them to lose or gain weight. Supplements are also very easy to get. Supplements come in many forms, such as powders, tablets, capsules and liquids. "The terms banned drug and banned substance refer to chemicals that are prohibited for use during athletic training and competition"(supplementquality). Many people don't care what will happen to them in the long run, as long as they can win and look good. Many athletes do not know the risks of the supplements they are using. A poll of US Olympians showed that 98 percent would use illegal supplements if they knew they wouldn't get caught. This same poll showed that over 50 percent would take the same supplement and win every competition for 5 years and then die (Metzl). This shows how far some athletes will go to win. "To make things complicated, different sport organizations ban different substances, if they ban anything at all. For example, Major League Baseball has not banned such performance-enhancing substances as androstenedione or steroids. When Mark McGwire used the supplement androstenedione when he set a home run record in 1998, he received no penalty, even though the human body rapidly converts this compound to testosterone, which builds muscle mass. The International Olympic Committee (IOC), National Football League (NFL), National Basketball Association (NBA) and National Collegiate Athletic Association all prohibit use of androstenedione. The NFL, NBA and IOC prohibit steroids and test for them. The National Hockey League and Major League Baseball have no policy regarding steroid use"(supplementquality).
