The Times is running a very sane article on the hype surrounding growth hormones in the "anti-aging" marketplace. "Taking hormones to hold back the years is based on a myth. And, for people who have no medical need for hormone supplementation, swallowing the dream could hold fatal risks. ... Extensive work from Scandinavia has shown that injecting the hormone does not restore muscle mass or fitness to the elderly." Unlike calorie restriction, there simply isn't an overwhelming weight of science and knowledge backing the use of hormones - and most of the widely available (and useless) products are sold by the shady, disreputable end of the "anti-aging" industry. Buyer beware.
