Motilin-related peptide · Growth hormone secretagogue

Ghrelin is a 28-amino-acid acylated peptide hormone primarily produced by gastric X/A-like cells and is the endogenous ligand for the growth hormone secretagogue receptor (GHS-R1a). It stimulates GH release, increases appetite and food intake, promotes energy storage, and modulates sleep and mood. Research explores ghrelin axis manipulation for obesity, cachexia, heart failure, and neurodegenerative diseases.

Pralmorelin · Growth Hormone-Releasing Peptide 2

GHRP-2 is a synthetic hexapeptide and potent ghrelin receptor agonist that stimulates growth hormone release from the pituitary. It produces a strong GH pulse with some elevation of cortisol and prolactin at higher doses. Research includes GH deficiency diagnosis, body composition, sleep quality, and appetite stimulation via its ghrelin-mimetic mechanism.
