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.

Growth Hormone Axis
GHRP-6

Ghrelin-mimetic GH secretagogue researched for appetite and recovery.

Mechanism

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.

Research areas
  • Endogenous GH pulse stimulation
  • Appetite stimulation in cachexia models
  • Cardioprotective signaling (preclinical)
Considerations
  • Increases appetite and may elevate cortisol/prolactin more than newer secretagogues.
  • Not FDA-approved; banned by WADA.

Growth Hormone Axis
Ipamorelin

Selective GH secretagogue with a clean research profile.

Mechanism

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.

Research areas
  • Endogenous GH release without cortisol elevation
  • Sleep quality and recovery markers
  • Lean tissue retention in catabolic states
Considerations
  • Generally well tolerated in research; long-term human safety data are limited.
  • Not FDA-approved.
  • Use in sport is prohibited (WADA).
