HGH usually refers to somatropin, recombinant human growth hormone — a 191-amino-acid protein identical to the growth hormone made by the pituitary gland. As an approved prescription drug (sold as Genotropin, Norditropin, and others) it is used to treat genuine growth-hormone deficiency and certain growth disorders under medical supervision.

It depends on the use. Somatropin is a legal, approved prescription medicine for defined growth-hormone-deficiency and growth disorders. In the United States, however, distributing HGH for non-approved uses such as anti-ageing or athletic enhancement is specifically prohibited by federal law (21 U.S.C. §333(e)).

Does HGH work for anti-aging or bodybuilding?

The evidence does not support these uses. A systematic review in healthy older adults found only small body-composition changes offset by higher rates of adverse events, and concluded growth hormone cannot be recommended as an anti-ageing therapy. Athletic and bodybuilding use is unproven, unsafe without supervision, and prohibited in sport and, in the US, by law.

Is HGH approved and prescription-only?

Yes. Somatropin is an approved, prescription-only medicine in the EU and US for specific growth-hormone-related conditions. It is administered and monitored by clinicians, and non-medical use falls outside that approval — and, in the US, outside the law. This page is educational information, not medical advice.

What is HGH actually prescribed for?

Somatropin is prescribed for genuine growth-hormone deficiency and for defined growth disorders in children and adults, including certain conditions that cause short stature. These uses are supported by strong clinical evidence and regulatory approval, in contrast to the anti-ageing and performance uses that are not approved.

Short answer

Recombinant growth hormone, approved for genuine GH deficiency and specific growth disorders. Anti-ageing and body-composition use in healthy adults is not supported and is legally restricted in the US.

What is known?

Somatropin is recombinant human growth hormone (HGH), a 191-amino-acid protein identical to the growth hormone made by the pituitary gland. It is an approved prescription drug used to replace deficient growth hormone or treat certain growth disorders under medical supervision.

What is not established?

Strong clinical evidence and regulatory approval support its use in genuine growth-hormone deficiency and defined paediatric growth disorders. For anti-ageing or body-composition use in healthy adults, a systematic review (Annals of Internal Medicine, 2007) found only small body-composition changes offset by higher rates of adverse events, and concluded it cannot be recommended as an anti-ageing therapy.

Safety

A prescription hormone with significant risks, including fluid retention, joint and muscle pain, carpal tunnel syndrome, and insulin resistance or impaired glucose tolerance. It is contraindicated in acute critical illness and active malignancy, with an increased-mortality signal in critically ill patients. Non-medical use is unsafe and, in the US, unlawful.

Regulatory status

An approved prescription medicine (somatropin) in the EU and US for defined growth-hormone-deficiency and growth disorders in children and adults. In the US, distributing HGH for non-approved uses such as anti-ageing or athletic enhancement is specifically prohibited by federal law (21 U.S.C. §333(e)). Prescription-only.

What is it?

Research and evidence

Somatropin is recombinant human growth hormone (HGH), a 191-amino-acid protein identical to the growth hormone made naturally by the pituitary gland. As an approved prescription drug — sold under brand names such as Genotropin and Norditropin — it is used to replace deficient growth hormone or to treat certain defined growth disorders under medical supervision. It is a prescription-only medicine, and that status is central to understanding both its legitimate use and the controversy around its misuse.

The clinical evidence is strong where the indication is genuine. Regulatory approval and robust trials support somatropin for true growth-hormone deficiency and for specific paediatric growth disorders in both children and adults. The picture is very different for the anti-ageing and body-composition uses that dominate online discussion: a systematic review in healthy older adults (Annals of Internal Medicine, 2007) found only small changes in body composition, offset by higher rates of adverse events, and concluded that growth hormone cannot be recommended as an anti-ageing therapy. Its mechanism — growth-hormone-receptor agonism that drives IGF-1 production, lipolysis, and protein anabolism — is well characterized, but a real biological effect is not the same as a safe or beneficial one in healthy people.

HGH is a prescription hormone with significant risks, including fluid retention, joint and muscle pain, carpal tunnel syndrome, and insulin resistance or impaired glucose tolerance. It is contraindicated in acute critical illness and active malignancy, and an increased-mortality signal has been reported in critically ill patients. Non-medical use is unsafe, and in the United States it is also unlawful: federal law (21 U.S.C. §333(e)) specifically prohibits distributing HGH for non-approved uses such as anti-ageing or athletic enhancement.
