Sylvester Stallone recently came under fire after he defended his use of human growth hormone to bulk up for his new "Rambo" movie. Some people believe the hormone has anti-aging effects, because the hormone naturally peaks at adolescence and is associated with renewed strength and sex drive. Bodybuilders and athletes take human growth hormone because they believe it will increase muscle mass and shed fat. But is there any promise in any of these notions?
Not only are certain uses of growth hormone illegal, researchers also point out that it is linked to diabetes, arthritis, heart disease and possibly cancer. So what should you believe about human growth hormone?
