At their annual meeting in Chicago on Monday, AMA delegates adopted a new policy on products such as HGH, DHEA and testosterone used as aging remedies.
With HGH, or human growth hormone, the AMA says evidence suggests long-term use can present more risks than benefits. The risks include tissue swelling and diabetes.
And the AMA says there's no credible evidence that other hormones, so-called bio-identicals, are safer than traditional estrogen and progesterone products.
The traditional hormones are only recommended for menopause symptoms at the lowest possible dose because of long-term health risks.
The AMA says anti-aging hormone promoters need rigorous studies to prove, or disprove, their claims.
