Lance Armstrong Doping Cover-Up

Lance Armstrong's doping operation remains the most systematic betrayal in sports history. The U.S. Anti-Doping Agency's 2012 report proved he oversaw a program that involved banned blood transfusions, EPO use, and intimidation of teammates who refused to participate. All seven Tour de France titles from 1999 to 2005 were stripped, and he lost over $75 million in endorsements. The coordinated cover-up, which included falsified medical records and threats against whistleblowers, exploited a sport where less than 2% of tests ever detected EPO during his reign.
