Common questions about Human Growth Hormone (HGH)
What is Human Growth Hormone (HGH) used for?
Human Growth Hormone (HGH) is most often marketed for Raises lean body mass (~2 kg) — but this is largely fluid, not functional muscle, Does NOT improve strength or exercise capacity despite marketing claims, Legitimately effective only for diagnosed childhood/adult GH deficiency and a few specific conditions, prescribed by an endocrinologist, Anti-aging 'rejuvenation' claims are not supported and the original researcher disavowed that use. Builds water-weight, not strength — banned, harmful, illegal to sell
Does Human Growth Hormone (HGH) work — what does the evidence say?
Banned / Harmful evidence. Linked to serious harm and/or banned in sport and many jurisdictions. Listed for awareness and safety only — NOT a recommendation. Human growth hormone (somatropin) is a pituitary hormone produced by recombinant DNA technology and FDA-approved to treat childhood and adult GH deficiency, Turner and Prader-Willi syndromes, and a few other conditions. Its use for bodybuilding, athletic performance, and 'anti-aging' is a separate, unapproved phenomenon: a 2008 Annals of Internal Medicine systematic review (Liu et al.) found GH raised lean body mass by about 2.1 kg in healthy young subjects but did NOT improve strength or exercise capacity and increased adverse events such as soft-tissue edema and fatigue — and much of the 'lean mass' gain is fluid, not muscle. The anti-aging craze traces to Rudman's small 1990 NEJM study of older men, which Rudman himself said had no anti-aging implications; later JAMA commentaries (Perls and colleagues) documented widespread illegal distribution and stressed that under 21 U.S.C. 333(e) it is a federal crime to distribute HGH for anti-aging, bodybuilding or athletic enhancement. GH and its secretagogues are on the WADA Prohibited List (class S2) banned at all times, though detection is difficult given GH's short half-life. Related agents sold alongside it — the GH-releasing peptides sermorelin, CJC-1295, ipamorelin, GHRP-2/6 and hexarelin, the oral ghrelin mimetic MK-677 (which raised fat-free mass without improving strength and worsened insulin sensitivity), and IGF-1 — share the same regulatory and safety problems. Key harms mirror acromegaly: insulin resistance and diabetes, edema, arthralgia, carpal tunnel, cardiomyopathy and other cardiovascular complications, and theoretical IGF-1-mediated cancer concerns.
What is the typical dose of Human Growth Hormone (HGH)?
Legitimate medical dosing is individualized by an endocrinologist based on weight, IGF-1 levels and the diagnosed deficiency; there is no safe or approved dose for muscle-building, athletic performance, or anti-aging.
Is Human Growth Hormone (HGH) safe? Any cautions or side effects?
Common GH-related adverse effects include fluid retention with peripheral edema, arthralgia and joint stiffness, carpal tunnel syndrome, and myalgia; metabolically it causes insulin resistance, glucose intolerance and can precipitate type 2 diabetes. Chronic excess produces acromegaly-like features (bony/soft-tissue overgrowth, organ enlargement) and cardiovascular harm including cardiomyopathy, heart failure, arrhythmia, valvular disease and hypertension. There is a theoretical, biologically plausible cancer concern from elevated IGF-1. Black-market and 'anti-aging'/internet products carry added risks of counterfeit, contaminated, or mislabeled material and unsterile injection. GH interacts with insulin and oral hypoglycemics (worsening glycemic control), corticosteroids, and oral estrogens, and can unmask adrenal insufficiency or thyroid changes. It should be used only for an FDA-approved indication under direct endocrinologist supervision; using or distributing it for performance, bodybuilding, or anti-aging is unproven, banned in sport, and illegal in the US.
