Woods revealed that federal agents questioned his agent at IMG, Mark Steinberg, over the issue. However, he denied taking any human growth hormone from Galea. “He never gave me HGH (human growth hormone) or any PEDs (performance-enhancing drugs. I have never taken any of those," the New York Daily News quoted him as saying.
Galea provided platelet-rich plasma therapy or "blood-spinning," to many popular athletes, including Woods. As part of the treatment, a small amount of blood is drawn and spun in a centrifuge, then returned to the patient in an attempt to heal injuries.
Woods, speaking at a press conference at Augusta National ahead of his participation in the Masters this week, admitted to have received the treatment at his home in Florida. He concluded that he would offer "full cooperation" in the investigation. Galea has been charged with four drug-related charges in Canada and is now facing a grand jury investigation in the U.S.
Investigators have questioned other sportsmen too, including Carlos Beltran and Jose Reyes of the Mets apart from Yankee third baseman Alex Rodriguez.
