What do home run king Mark McGwire, French tennis champ Mary Pierce, international soccer star Zinedine Zidane, British sprinter Linford Christie, and NFL tight end Shannon Sharpe all have in common All have spoken openly to the media about their use of creatine supplements in athletic training. 

The full impact that the well-publicized use of supplements by sports icons has had on young athletes worldwide is difficult to determine. A 2000 survey by the Kaiser Family Foundation found that 73% of 10-17 year olds surveyed cited a famous athlete as someone they looked up to or wanted to be like. And while 55% were aware of Mark McGwire s use of andro, only 5% reported ever having purchased a dietary supplement because of a famous athlete. Yet the fact remains that performance-enhancing supplement use is at an all-time high among America s youth. 

A related compound, androstenedionc is a precursor to testosterone and was marketed over the counter as an alternative to the illegal steroids to enhance strength and performance. Mark McGwire made Andro famous when he admitted to using it during his record-breaking home run streak in 1998. Because androstenedione was associated with many of the side effects of anabolic steroids, the FDA made it an illegal substance in 2004.
