GHRP-2 vs Tesamorelin
An educational, source-based comparison of GHRP-2 and Tesamorelin — how each peptide works, what it's researched for, and what to know before going deeper.
A synthetic hexapeptide that activates the ghrelin/GHS-R1a receptor, stimulating endogenous GH release. Compared to Ipamorelin, GHRP-2 produces a stronger GH pulse but also modestly elevates cortisol, prolactin, and appetite.
- GH release in adult GH deficiency
- Appetite stimulation in cachexia models
- Diagnostic GH stimulation testing
- • Not FDA-approved.
- • Less receptor-selective than Ipamorelin; expect appetite and cortisol effects.
- • Prohibited by WADA.
A stabilized analog of growth hormone-releasing hormone (GHRH) that stimulates pulsatile endogenous GH and IGF-1 release. FDA-approved (Egrifta) for the reduction of excess abdominal visceral fat in HIV-infected patients with lipodystrophy.
- Visceral adipose tissue reduction (approved)
- Cognitive function in older adults (research)
- NAFLD / hepatic fat (research)
- • FDA-approved only for HIV-associated lipodystrophy.
- • May affect glucose tolerance; monitor in at-risk patients.
- • Requires physician oversight.
GHRP-2 vs Tesamorelin — Key differences
- Class: GHRP-2 is classified as Growth Hormone Axis, while Tesamorelin is Growth Hormone Axis.
- Primary research focus: GHRP-2 — gh release in adult gh deficiency; Tesamorelin — visceral adipose tissue reduction (approved).
