The US Anti-Doping Agency has pressed doping charges against seven-time Tour de France champion Lance Armstrong.
Armstrong is facing a lifetime ban from cycling and being stripped of his record seven Tour de France titles. The USADA has banned him from triathlons, a sport that he took up after cycling.
The charges were first reported by The Washington Post.
A letter from the USADA has accused Armstrong of using EPO, blood transfusions, testosterone, HGH, and anti-inflammatory steroids. The letter from the USADA has not cited specific examples, but says the charges are based upon investigations on Armstrong's former teams.
The letter goes on to say that blood collected from Armstrong by cycling's governing body in 2009 and 2010 are "fully consistent with blood manipulation including EPO use and/or blood transfusions"
Armstrong denied his involvement in a statement: "I have never doped, and, unlike many of my accusers, I have completed as an endurance athlete for 25 years with no spike in performance, passed more than 500 drug tests and never failed one."
Armstrong is currently in France training for a triathlon.
