Hard to detect, easy to use, human growth hormone still stumps anti-doping forces

USATODAY.com: "There isn't much stopping cheaters from using human growth hormone these days. In the minds of many experts, it has become the most insidious drug on the long list of banned substances in sports. Ten years since HGH became a household item in the doping kits of dirty athletes, the problem seems little closer to being resolved. Anti-doping leaders still are trying to find a test to efficiently detect it. Law enforcement is making inroads into distribution networks but is struggling to find ways to prosecute people for using HGH. And buoyed by the fact that it's hard to get caught, athletes also seem to be ignoring the drug's possible negative side effects."
