For testing positive for the over-the-counter supplement DHEA, OJ Mayo will serve a 10-game suspension, beginning this Friday. Per the Memphis Commercial Appeal: “The NBA announced today that Grizzlies guard O.J. Mayo has been suspended without pay for 10 games for violating the terms of the league’s anti-drug program. His violation of the program involved a positive test for dehydroepiandrosterone. DHEA is commonly available in health food stores and pharmacies. It is a steroid hormone that acts on the body much like testosterone. [...] ‘I’m extremely disappointed that I’m going to miss the next 10 games, particularly as our team is making a push for the playoffs,’ Mayo said in a statement. ‘I had no idea that the over-the-counter supplement that I took was a substance banned by the NBA. It was an honest mistake, but I take full responsibility for my actions. I apologize to my fans, teammates and the Grizzlies organization for regrettably not doing the necessary research about what supplements I can put in my body.’”
