UNDATED (CBS) -- After years of brazen denials, cyclist Lance Armstrong finally admitted last night he used performance enhancing drugs to help him win all 7 Tour de France championships.
Lance Armstrong's long awaited confession came after Oprah Winfrey's first question of "Did you ever take banned substances to enhance your cycling performance?"
Armstrong told the world his unprecedented cycling career would not have been possible without doping. He said, "This situation is one big lie, that I repeated a lot of times."
The disgraced cyclist said he used blood transfusions, testosterone and the blood booster, EPO to get ahead. He said it didn't feel wrong, but scary.
Armstrong did not consider his conduct cheating. He said it leveled the playing field during a time when many competitors were also doping. He said, "I didn't invent the culture, but I didn't try to stop the culture, that's what I have to be sorry for."
He denied threatening teammates on his U.S. Postal Service Team to use drugs, but he admitted bullying them to do just about everything else his way. Armstrong said, "It is a major flaw, it is a guy who expected all outcomes to come his way. When I say there will be people who hear this and never forgive me, I understand that."
The U.S. anti-doping Agency stripped Armstrong of his tour titles last year when it found evidence the cyclist used performance enhancing drugs. After last night's interview, the agency said if Armstrong is sincere about correcting past mistakes he will testify under oath about the full extent of his doping activities. Armstrong's charity, Livestrong said it was disappointed that he quote "misled people - during and after his cycling career - including us".
Armstrong said he stopped doping in 2005 and was not using performance enhancing drugs during his comeback in 2009.
