A Canadian doctor has pleaded guilty to charges he brought unapproved and misbranded drugs into the U.S. in a Buffalo courthouse on Wednesday. Dr. Anthony Galea, 51, who has treated a number of NFL players, Olympic medalists and even Tiger Woods, accepted responsibility for a five-count indictment by a federal grand jury handed out last October. Prosecutors had accused him of traveling to the U.S. multiple times between 2007 and 2009 to administer treatments using growth hormones and Actovegin (derived from calf’s blood) that were not sanctioned for use by either the Canadian or U.S. governments. Galea was arrested in October 2009 by the RCMP at his office in Etobicoke, ON, and will be sentenced on October 19. He faces up to 24 months in prison and a fine of up to $40,000 if convicted.
