Synopsis

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Performance-enhancing drugs are substances used by athletes to improve their performances in the sports in which they engage.The classification of substances as performance-enhancing drugs is not entirely clear-cut and objective. As in other types of categorization, certain prototype performance enhancers that are universally classified as such (like anabolic steroids), whereas other substances (like vitamins and protein supplements) are virtually never classified as performance enhancers despite their significant effects on athletes' performance. As is usual with categorization, there are borderline cases; caffeine, for example, is considered a performance enhancer by some athletic authorities but not others.
