Illegal use of human growth hormone common among young male weightlifters

A new study at Harvard Medical School reveals that illicit use of HGH (human growth hormone) has become common among young American male weightlifters. Additionally, illicit HGH use in this population is often associated with polysubstance abuse involving both performance-enhancing and classical drugs.
HGH, once an expensive performance-enhancing drug used exclusively by elite athletes, has become cheaply available for illicit users. The study findings suggest that illicit HGH use is common, and is usually associated with abuse of both AAS and ordinary street drugs.
The study is published in The American Journal on Addictions.
