GHRP-6 vs Ipamorelin
An educational, source-based comparison of GHRP-6 and Ipamorelin — how each peptide works, what it's researched for, and what to know before going deeper.
A hexapeptide ghrelin receptor (GHS-R1a) agonist that stimulates pituitary GH release and increases appetite via central ghrelin pathways. One of the earliest GH-releasing peptides studied.
- Endogenous GH pulse stimulation
- Appetite stimulation in cachexia models
- Cardioprotective signaling (preclinical)
- • Increases appetite and may elevate cortisol/prolactin more than newer secretagogues.
- • Not FDA-approved; banned by WADA.
A selective ghrelin/GHS-R1a receptor agonist that stimulates GH release with minimal effect on cortisol, prolactin, or appetite — distinguishing it from older secretagogues like GHRP-6.
- Endogenous GH release without cortisol elevation
- Sleep quality and recovery markers
- Lean tissue retention in catabolic states
- • Generally well tolerated in research; long-term human safety data are limited.
- • Not FDA-approved.
- • Use in sport is prohibited (WADA).
GHRP-6 vs Ipamorelin — Key differences
- Class: GHRP-6 is classified as Growth Hormone Axis, while Ipamorelin is Growth Hormone Axis.
- Primary research focus: GHRP-6 — endogenous gh pulse stimulation; Ipamorelin — endogenous gh release without cortisol elevation.
