Was one of those EPO? "Yes.''
Did he do blood doping and use transfusions? "Yes.''
Did he use testosterone, cortisone and human growth hormone? "Yes.''
Did he take banned substances or blood dope in all his Tour wins? "Yes.''
Along the way, Armstrong cast aside teammates who questioned his tactics, yet swore he raced clean and tried to silence anyone who said otherwise. Ruthless and rich enough to settle any score, no place seemed beyond his reach -- courtrooms, the court of public opinion, even along the roads of his sport's most prestigious race.
That relentless pursuit was one of the things that Armstrong said he regretted most.
"It's a major flaw, and it's a guy who expected to get whatever he wanted and to control every outcome. And it's inexcusable. And when I say there are people who will hear this and never forgive me, I understand that. I do.''
Anti-doping officials have said nothing short of a confession under oath -- "not talking to a talk-show host,'' is how World Anti-Doping Agency director general David Howman put it -- could prompt a reconsideration of Armstrong's lifetime ban from sanctioned events.
He's also had discussions with officials at the U.S. Anti-Doping Agency, whose 1,000-page report in October included testimony from nearly a dozen former teammates and led to stripping Armstrong of his Tour titles. Shortly after, he lost nearly all his endorsements and was forced to walk away from the Livestrong cancer charity he founded in 1997.
Armstrong could provide information that might get his ban being reduced to eight years, according to a person with knowledge of the situation. By then, Armstrong would be 49. He returned to triathlons, where he began his professional career as a teenager, after retiring from cycling in 2011, and has told people he's desperate to get back.
There were very few details about Armstrong's performance-enhancing regimen that would surprise anti-doping officials.
What he called "my cocktail'' contained the steroid testosterone and the blood-booster erythropoetein, or EPO, "but not a lot,'' Armstrong said. That was on top of blood-doping, which involved removing his own blood and weeks later re-injecting it into his system.
All of it was designed to build strength and endurance, but it became so routine that Armstrong described it as "like saying we have to have air in our tires or water in our bottles.''
"That was, in my view, part of the job,'' he said.
