Scientifically proven dangers of human growth hormone include carpal tunnel syndrome; edema; muscle, nerve or joint pain; and tingling or numb skin, according to WebMD. Other dangers include increased cholesterol levels and risk of cancerous tumors and diabetes. People who obtain the hormone illegally risk receiving counterfeit, adulterated or unapproved products that can be dangerous. Physicians always administer human growth hormone prescriptions by injection. Patients should talk to their doctors before taking human growth hormone in any form.
Consumers who purchase and use products that purport to be human growth hormone in pill or spray form risk unknown dangers, notes WebMD.There is no reputable evidence that consumers who use these products to increase energy, reduce fat or build muscle obtain the same results as they obtain with prescription injections.The stomach digests oral doses of human growth hormone before the body absorbs them.
In 1985, the U.S. Food and Drug Administration approved synthetic human growth hormone for certain uses by adults and children, explains WebMD. Approved uses for adults include treating human growth hormone deficiency resulting from pituitary tumors; short bowel syndrome, a disorder in which the body does not absorb nutrients properly; and muscle atrophy associated with HIV/AIDS. Approved uses for children include treating stunted growth in girls due to Turner's syndrome and chronic kidney disorders.
Sometimes individuals combine the growth hormone with drugs such as anabolic steroids, attempting to enhance muscle strength and boost physical performance, states WebMD. Scientists do not know what effect these substances have on the body for such purposes, as they are not FDA-approved uses.
