GHRP
Definition
Growth hormone-releasing peptide: a peptide secretagogue that can stimulate growth hormone release through the growth hormone secretagogue receptor pathway.

GHRP is not growth hormone
A secretagogue stimulates secretion; it is not the hormone being secreted. Work identifying the growth hormone secretagogue receptor established a signaling route distinct from simply administering GH. The broader secretagogue category also includes nonpeptide molecules, so not every GH secretagogue is a peptide.

How to read an endocrine study
Check whether the reported result is a short-term GH peak, integrated hormone exposure, an IGF-1 measurement or a patient outcome. A hormone response may demonstrate biological activity without demonstrating improved strength, sleep or recovery. The study population and follow-up determine which conclusions are supportable.
Naming matters
GHRP, GHRH and GH are different terms. Do not assume that products sharing a growth hormone-related label have the same receptor, duration, evidence or adverse effects. An observed hormonal effect is a starting point for investigation, not a ready-made clinical protocol.
