Lance Armstrong Doping Scandal (2012)

Lance Armstrong's doping scandal is the most systematic fraud in sports history, stripping him of seven Tour de France titles. From 1999 to 2005, he ran the most sophisticated programme cycling has ever seen, using EPO, blood transfusions, testosterone, and cortisone. The USADA's 2012 report called it "the most successful doping programme sport has ever seen." Unlike #1's singular cheat, this affected 21 teammates and cost Livestrong its credibility. Armstrong's lifetime ban and $5 million settlement contrast sharply with his former fame. Over 1,000 blood samples were manipulated. The scandal still angers fans, as his cancer charity—built on a lie—was collateral damage, raising ethical questions about hero worship.
