GHRP-2 vs Sermorelin
An educational, source-based comparison of GHRP-2 and Sermorelin — 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 synthetic 29-amino-acid analog representing the active fragment of endogenous GHRH. Stimulates the pituitary to release GH in a physiologic, pulsatile pattern. Previously FDA-approved (Geref) for pediatric GH deficiency diagnosis before discontinuation for commercial reasons.
- Adult GH deficiency
- Pediatric short stature (historical)
- Sleep quality and body composition in aging
- • No longer commercially available as an FDA-approved drug; available via compounding.
- • Requires physician oversight.
- • Banned in competitive sport.
GHRP-2 vs Sermorelin — Key differences
- Class: GHRP-2 is classified as Growth Hormone Axis, while Sermorelin is Growth Hormone Axis.
- Primary research focus: GHRP-2 — gh release in adult gh deficiency; Sermorelin — adult gh deficiency.
- Tag: Growth hormone vs Growth hormone.
