Armstrong denies latest doping accusations August 23, 2005 at 4:56 PM CDT - Updated July 26 at 5:26 PM Tour de France champion Lance Armstrong denies a report he used a performance-enhancing drug to help him win his first Tour six years ago. Armstrong's Web site calls the story in the French sports daily, L'Equipe, a "witch hunt." The Tour de France director says the report appears to be credible. But he warns against making snap judgments. Even if it's accurate, he says disciplinary is unlikely. The paper's investigation was based on tests of the second of two urine samples. The first samples were used up in 1999 for analysis at the time. The paper's front-page headline is "The Armstrong Lie." It says signs of the drug, E-P-O, were found in samples of Armstrong's urine that were taken six times during the 1999 race. E-P-O builds endurance by boosting the production of red blood cells, which are rich in oxygen.
