§ Definition
A growth-hormone secretagogue is any molecule that stimulates the pituitary gland to secrete growth hormone, acting at either the ghrelin receptor (GHS-R1a) or the GHRH receptor. In research the term covers both peptide and non-peptide agents, and combining a GHRH-type and a GHRP-type secretagogue is a common experimental strategy because the two receptors reinforce one another.
