Controversies regarding the use of human growth hormone (HGH) as treatment method have centered on the claims, products, and businesses related to the use of
growth hormone

History
A study was published in ''

''The New England Journal of Medicine'' (''NEJM'') is a weekly medical journal published by the Massachusetts Medical Society. It is among the most prestigious peer-reviewed medical journals as well as the oldest continuously published one.

'' in 1990 by Rudman ''et al.'', which showed fat loss, muscle mass increase and maintenance of healthy skin from the administration of growth hormone in twelve elderly men. Despite the fact the authors at no time claimed that GH had reversed the aging process itself, their results were misinterpreted as indicating that GH is an effective anti-aging agent.
This study, and others, has led to organizations such as the controversial

promoting the use of this hormone as an "anti-aging agent".
Additionally, companies selling
dietary supplements have websites selling products that claim to be linked to GH in the advertising text, with medical-sounding names described as "HGH Releasers". Typical ingredients include amino acids, minerals, vitamins, and/or herbal extracts, the combination of which are described as causing the body to make more GH with corresponding beneficial effects. In the United States, because these products are marketed as dietary supplements it is illegal for them to contain GH, which is a drug. Also, under United States law, products sold as dietary supplements cannot have claims that the supplement treats or prevents any disease or condition, and the advertising material must contain a statement that the health claims are not approved by the FDA. The FTC and the FDA do enforce the law when they become aware of violations.
As a result of the reactions to the 1990 article and its frequent citation by proponents of HGH as an anti-aging agent, in 2003 the NEJM published two articles that came out strongly and clearly stating that there was insufficient medical and scientific evidence to support use of HGH as anti-aging drug. One article was written by the Journal's then-current editor in chief, Jeffrey M. Drazen, M.D. and was entitled, "Inappropriate Advertising of Dietary Supplements". It focused mostly on the advertising of dietary supplements. The other article was written by the editor-in-chief at the time the 1990 article was published, Mary Lee Vance, M.D., and was entitled, "Can Growth Hormone Prevent Aging?"; it focused more on the medical issues around whether there was sufficient evidence to use HGH as an anti-aging agent.

While it is possible that there are some advantages, such as an increase in lean body mass, it is also evident that benefits are being exaggerated by some for commercial gain and ineffective products are being sold to unsuspecting consumers.

), and affects the quality of life without significant side effects.
It must be emphasized that these studies were small—only tens of patients—and the results were therefore stated tentatively; in the words of one of the cited sources: "Clearly more studies are needed before GH replacement for the elderly becomes established. Safety issues will require close scrutiny, but the data available so far are sufficiently positive to undertake large multicentre, placebo-controlled trials, particularly looking at endpoints associated with prevention of frailty and loss of independence."
Side-effects of high doses and long-term use
Some of the side effects reportedly seen in previously healthy mature patients after taking high HGH doses include:
*
Edema (retention of fluids) in extremities
*
Arthralgia

Chronic use of HGH is not well studied. However, in Europe a study called "SAGhE" was undertaken to study these long-term effects of HGH in children. It found that persons with certain kinds of short stature (idiopathic growth hormone deficiency and idiopathic or gestational short stature) who were treated with recombinant human growth hormone during childhood and who were followed over a long period of time, were at a small increased risk of death when compared to individuals in the general population of France. The FDA issued a Safety Alert reporting this result.

Bureaucrats vs. Physicians: Have Doctors Been Stripped of Their Power to Determine the Proper Use of Human Growth Hormone in Treating Adult Disease?
Journal of Law & Policy 27 pp 191–217 which reads:
Prohibited distribution of human growth hormone.
(1) Except as provided in paragraph (2), whoever knowingly distributes, or possesses with intent to distribute, human growth hormone for any use in humans other than the treatment of a disease or other recognized medical condition, where such use has been authorized by the Secretary of Health and Human Services under section 355 of this title and pursuant to the order of a physician, is guilty of an offense punishable by not more than 5 years in prison, such fines as are authorized by title 18, or both.
(2) Whoever commits any offense set forth in paragraph (1) and such offense involves an individual under 18 years of age is punishable by not more than 10 years imprisonment, such fines as are authorized by title 18, or both.
(3) Any conviction for a violation of paragraphs (1) and (2) of this subsection shall be considered a felony violation of the Controlled Substances Act 1 U.S.C. 801 et seq.for the purposes of forfeiture under section 413 of such Act 1 U.S.C. 853
(4) As used in this subsection the term “human growth hormone” means somatrem, somatropin, or an analogue of either of them.
(5) The Drug Enforcement Administration is authorized to investigate offenses punishable by this subsection.
This section has been taken by some, most notably[ the authors of a commentary article published in the '' Journal of the American Medical Association'' in 2005, as meaning that ''prescribing'' HGH off-label may be considered illegal. "Physicians and other health care professionals should be aware that current law explicitly prohibits the distribution of GH except for clearly and narrowly defined indications. Distribution for other uses, or off-label use, such as for antiaging, age-related conditions, and enhancing athletic performance, are illegal. Although GH is not a schedule III drug, section 303 33f(5) of the FDCA clearly provides the Drug Enforcement Administration with the responsibility of enforcing the laws governing human GH. Given the clinical concerns and the legal issues involved, we believe that physicians or other persons who currently market, distribute, or administer GH to their patients for any reason other than the well-defined approved (ie, legal) uses of the drug, should not do so."
