United States Anti-doping Agency

Britain's Sunday Times said a USADA report -- obtained by the Fancy Bears hacking group -- had found Alberto Salazar abused prescription drugs and experimented with infusions of a research supplement based on the amino acid L-carnitine at his Oregon base.

Lance Armstrong was stripped of his Tour de France titles and given a life-ban from cycling by the United States Anti-Doping Agency (USADA) in 2012 for doping.

Lance Armstrong, 43, was stripped of his Tour titles and given a life-ban from cycling by the United States Anti-Doping Agency (USADA) in 2012, having denied for years he was a drugs cheat. The cancer-survivor eventually made a public confession in a television interview with US chat show host Oprah Winfrey in 2013.

Former world double sprint champion Tyson Gay has been suspended for one year after testing positive for a banned substance, the US Anti-Doping Agency (USADA) said on Friday.

The United States Anti-Doping Agency announced Friday that Ramos had been banned for two years after testing positive June 14, reports Xinhua.

The United States government decided on Friday to join a doping lawsuit filed by one of Lance Armstrong's former teammates alleging that the disgraced cycling champion defrauded government sponsors.

Armstrong was banned for life when the US Anti-Doping Agency (USADA) found overwhelming evidence that he was at the heart of a sophisticated doping scheme when his US Postal Service team dominated the Tour de France.

The move comes after UCI said World Anti-Doping Agency and the United States Doping Agency had refused to co-operate with its investigations.

Lance Armstrong showed barely the slightest flicker of emotion when he confessed to cheating his way to a record seven Tour de France titles, but the American finally cracked when he recalled telling his children the truth about his doping-fueled career.

Tour de France organiser Christian Prudhomme said Thursday that disgraced rider Lance Armstrong, who was stripped of his seven Tour titles because of doping, "was already in the past".

The International Cycling Union announced on Monday that it will not appeal the United States Anti-Doping Agency's ruling to bar Lance Armstrong for life from Olympic sports for doping and for playing an instrumental role in the team-wide doping on his Tour de France-winning cycling squads.

Four years ago, the United States Anti-Doping Agency suspended Leogrande for using a blood-boosting hormone known as EPO. His case grew into the lengthy investigation that culminated in Lance Armstrong's lifetime ban from the sport.
