GHRP-6
Also known as: Growth Hormone Releasing Peptide-6
GHRP-6 is a synthetic hexapeptide (His-D-Trp-Ala-Trp-D-Phe-Lys-NH2) growth hormone secretagogue and ghrelin receptor agonist. Developed by Bowers and Momany and first described in 1984, it was the first synthetic GHRP characterized and is defined by its pronounced appetite-stimulating effect — the strongest of any clinically studied GHRP. It has never been approved by the FDA or any regulatory agency and remains a research-only compound used off-label in the grey market.

Activation of GHSRs Facilitates the Excitability of Dentate Gyrus Granule Cells and Short-Term Spatial Memory via Multiple Ionic and Signaling Mechanisms
Ghrelin is the endogenous ligand of the ghrelin secretagogue receptors (GHSRs). Although the GHSRs are densely expressed in the dentate gyrus (DG) granule cells (GCs), their roles in the DG GCs remain to be fully understood.

Growth hormone-releasing peptide 6 (GHRP-6) hydrogel for acute kidney injury therapy via metabolic regulation
Renal tubular epithelial cells (TECs), which are highly susceptible to injury during acute kidney injury (AKI), have notable regenerative effects on renal recovery after AKI. AKI-driven metabolic reprogramming of TECs plays a critical role in determining whether kidneys recover functionally or develop fibrosis.
