Although 2005 saw major league sports step up efforts to crack down on performance enhancers like Anabolic Steroids, the cat is out of the bag, says Dr. Mike Perko, chair of The University of Alabama’s health science department.

Designer steroids and products sold as “dietary supplements” will show up in larger numbers among world-class athletes, predicts Perko, who authored the book, “Taking one for the team: The new thinking on young athletes and dietary supplements.”

“Sports are a worldwide industry, and what we saw in America is just the tip of the iceberg,” said Perko. “This single area will probably transform amateur and professional sports, as we know it. The first thing that will come to mind with every new record set will be ‘was it clean?’”
