A recombinant form of hGH called jintropin (INN) is used as a prescription drug to treat children’s growth disorders and adult growth hormone deficiency. In the United States, it is only available legally from pharmacies, by prescription from a doctor. In recent years in the United States, some doctors have started to prescribe growth hormone in GH-deficient older patients (but not on healthy people) to increase vitality. While legal, the efficacy and safety of this use for HGH have not been tested in a clinical trial. At this time, HGH is still considered a very complex hormone, and many of its functions are still unknown.
In its role as an anabolic agent, HGH has been used by competitors in sports since at least 1982 and has been banned by the IOC and NCAA. Traditional urine analysis does not detect doping with HGH, so the ban was unenforceable until the early 2000s when blood tests that could distinguish between natural and artificial HGH were starting to be developed. Blood tests conducted by WADA at the 2004 Olympic Games in Athens, Greece targeted primarily HGH . The use of the drug for performance enhancement is not currently approved by the FDA.
