Biology & mechanism

A stabilised GHRH(1-44) analog bearing an N-terminal hexenoyl group that resists DPP-4 degradation. Stimulates pituitary GH release, raising IGF-1 and preferentially reducing visceral adipose tissue.

What the research actually shows

The only GHRH analog with a modern FDA approval. Phase 3 trials demonstrated visceral adipose tissue reduction in HIV-associated lipodystrophy. Studied subsequently in NAFLD in HIV populations.

Regulatory status

FDA-approved — narrowly — for reduction of excess abdominal fat in HIV-associated lipodystrophy. Prescription-only. Approval does not extend to general body composition or anti-ageing use.

Safety signals

Raises IGF-1; label cautions around malignancy risk given GH-axis stimulation. Contraindicated in pregnancy and active malignancy. Injection-site reactions, arthralgia, oedema. Prohibited in sport (WADA S2).
