Shamed former Tour de France champion Lance Armstrong admitted taking several banned performance enhancing substances, in a television interview broadcast Thursday.

Armstrong told US talk show host Oprah Winfrey that he had used blood transfusions and taken EPO, testosterone, cortisone, human growth hormone in all seven of his Tour victories starting in the 1990s.

He also confessed to using an array of banned substances in his seven Tour de France triumphs from 1999 to 2005, but denied using drugs in his comeback in 2009.

Armstrong, stripped of all his cycling achievements from August of 1998, told Winfrey that he was angered by the US Anti-Doping Agency's charge that he continued to dope when he returned to pro cycling and raced in the Tour de France in 2009 and 2010
