> Lance Armstrong never failed a drug test
That's not how I read this part of the Wikipedia article[1]:
> In June 2012, USADA accused Armstrong of doping and drug trafficking, based on blood samples from 2009 and 2010

Fair enough. I should specify he never failed a drug test from the period in which all of his UCI and Olympic wins were rescinded, which I believe was 1998 to 2005. I'm also reasonably sure he never got popped specifically for EPO. There has been a test to find recombinant EPO since 2000, but it can only detect its presence for something like 18 hours after injection and you only need to inject weekly. Out of other ways to blood dope, only tranfusion from another person is detectable by any means whatsoever. It's why they use the athlete biological passport instead and look for increases in red blood cell count or hematocrit that are not physiologically possible without doping.
