Those diagnosed with growth hormone deficiency can profit from synthetic injectable human growth hormones (HGH). This can include AIDS/HIV patients experiencing muscle wasting. Benefits include increased bone density, muscle mass and exercise capacity, and decreased body fat.

On the Other: Healthy Adults Gain Little at Too High a Cost

As we hit middle age, our natural output of growth hormones is reduced. According to the Mayo Clinic, there's little evidence that synthetic HGH will do much to increase muscle and reduce body fat in healthy adults that can't be accomplished through strength training. HGH is only available by prescription and effective only by injection, despite the claims of those who market pills, sprays and powders. Side effects for healthy adults can include muscle and joint pain and, for males, breast tissue enlargement---not to mention up to thousands of dollars in cost. HGH supplements can also complicate heart disease and diabetes.

Bottom Line

Stick with strength training as you age unless you have a diagnosed growth hormone deficiency. You'll gain all the benefits of synthetic HGH at a fraction of the cost and with none of the adverse side effects.
