'Miracle' HGH's Awful Truth: It May Not Work

Here’s the list of people human growth hormone is proven to help: the elderly, AIDS and tuberculosis patients, and people with hormone deficiencies. Baseball players aren’t on that list, Newsweek reports, and neither are thousands of ordinary people who believe HGH slows the aging process. “There’s a great deal of hype,” said one endocrinologist, “but there isn’t a great deal of evidence.”

For the elderly, who have stopped producing HGH naturally, the hormone is very beneficial, but younger people—like, say, pitcher Roger Clemens—are already producing plenty. Of course, clubhouse wisdom contradicts that. Team doctors swear it cuts recovery time in half. “Our observations tell us it works,” said a former NFL physician, “and it works well.” (More Roger Clemens stories.)
