The participants used growth hormone for an average of about six months.

While growth hormone did appear to increase lean muscle mass and reduce body fat by an average of just over 4 pounds, it did not appear to have an effect on other measures of fitness, including bone density, cholesterol and lipid levels.

"From our review, there's not data to suggest that growth hormone prolongs life, and none of the studies make that claim," Liu says.

Liu tells WebMD he was surprised to find so little research has been done on the use of growth hormones in the elderly population—especially since so many claims have been made about the treatment's benefits.

But he says he understands why people believe the hype.
