GHRP
Also known as: Growth Hormone Releasing Peptide · growth hormone secretagogue · GHS
Growth Hormone Releasing Peptide — a class acting on the ghrelin receptor to trigger pulsatile GH release.
GHRP (Growth Hormone Releasing Peptide) is a class of peptides that stimulate growth-hormone release by acting on the ghrelin / GH-secretagogue receptor — a different pathway from GHRH. Ipamorelin is a selective member of this class.
GHRPs prompt a pulse of the body’s own GH, and because they work through a separate receptor they are often paired with a GHRH analog for a synergistic research effect.
The broader umbrella term for any compound that prompts GH release — whether a GHRP or a GHRH analog — is growth hormone secretagogue.

RELATED TERMS
Secretagogue
A substance that prompts a gland to secrete a hormone — e.g. a GH secretagogue triggers the pituitary to release growth hormone.
GHRH
Growth-Hormone-Releasing Hormone — the hypothalamic hormone that signals the pituitary to release growth hormone.
Ipamorelin
A selective growth-hormone secretagogue (a pentapeptide) studied for pulsatile GH release with minimal effect on other hormones.
Receptor / Agonist
A receptor is a cell’s signal-receiving protein; an agonist binds it and activates it, an antagonist blocks it.
Half-Life
The time for a compound’s concentration to fall by half — a key determinant of dosing frequency in research.
