Growth hormone-releasing hormone (GHRH) analog — FDA-approved (Egrifta)

Tesamorelin

Tesamorelin (brand name Egrifta) is an FDA-approved growth hormone-releasing hormone (GHRH) analog indicated for the reduction of excess visceral abdominal fat in HIV-infected patients with lipodystrophy. It is the only GHS/GHRH-class peptide with current FDA approval. Its efficacy was established in a Phase 3 trial published in the New England Journal of Medicine.

Evidence snapshot

Track regulatory status and approved indication. Do not publish dosing, sourcing, or off-label treatment instructions. Maintain the FDA-approved indication as the primary framing; flag any off-label use claims.

Tesamorelin (Egrifta) received FDA approval in 2010 for the reduction of excess visceral abdominal fat in HIV-infected patients with lipodystrophy — the only GHRH/GHS-class peptide with FDA approval.

The pivotal Phase 3 trial was published in the New England Journal of Medicine (Falutz et al., 2010; PMID 20879920), showing significant reduction in visceral adipose tissue (VAT) over 26 weeks in HIV patients with lipodystrophy.

The FDA drug label (Egrifta) is available on accessdata.fda.gov; the approved administration route is subcutaneous injection.

Tesamorelin is a stabilized GHRH analog; its mechanism involves stimulating endogenous GH release, which in turn increases lipolysis and reduces visceral fat accumulation.

Tracked claims

Tesamorelin is FDA-approved for HIV-associated lipodystrophy.

Evidence level: Primary regulatory

Cite the FDA drug label directly. This is the only GHS/GHRH-class peptide with FDA approval. The indication is specific to HIV-associated lipodystrophy — not general obesity or cosmetic fat loss.

Phase 3 trial data showed significant reduction in visceral adipose tissue.

Evidence level: Peer reviewed

Sources: New England Journal of Medicine

Cite the Falutz et al. (2010) NEJM publication directly. The trial population was HIV patients with lipodystrophy — do not extrapolate to non-HIV populations.
