GHRP-6
Also known as: Growth Hormone Releasing Peptide-6, SK&F 110679
Synthetic hexapeptide GHS-R1a agonist with well-characterized preclinical profile in pituitary-axis research.
GHRP-6 is a synthetic hexapeptide developed in the late 1980s as part of the foundational generation of growth-hormone-releasing peptides.
It was instrumental in the discovery of the ghrelin-receptor system (GHS-R) that preceded the identification of ghrelin itself.The published research profile of GHRP-6 is extensive and spans several decades, covering GHS-R1a pharmacology, appetite-signaling in animal models, cardiac-tissue research, and comparative studies with other GHRPs.
It tends to have a more pronounced effect on ghrelin-pathway appetite signaling than its close relative GHRP-2.GHRP-6 is cataloged in standard 5mg and 10mg research formats.
Research applications
- Foundational GHS-R1a pharmacology
- Ghrelin-pathway and appetite signaling

GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic met-enkephalin analogue that stimulates GH release through the ghrelin receptor. It is noted for its strong appetite-stimulating properties and effects on GH pulsatility in research.
