How do performance-enhancing drugs affect athletes?
Performance-enhancing drugs (PEDs) are drugs that improve active performance in humans, known colloquially in sports as ‘doping’. Perhaps the most famous abuser of PEDs to date is Lance Armstrong, a seven-time Tour de France champion, who in 2013 confessed to using performance-enhancing drugs during his cycling career, and was stripped of the seven Tour de France titles he won from 1999 to 2005.
