HGH Peptides — Growth Hormone Secretagogue Guide

HGH peptides are short amino-acid sequences that stimulate the pituitary to release endogenous growth hormone, rather than supplying exogenous HGH directly. This guide covers the major growth-hormone-releasing peptides (GHRPs) and growth-hormone-releasing hormone (GHRH) analogues used in laboratory research.

Quick answer

HGH peptides are growth hormone secretagogues — research compounds that bind to GHRH or ghrelin receptors on the pituitary to trigger pulsatile release of the body's own growth hormone. The main reference compounds are sermorelin and tesamorelin (GHRH analogues), ipamorelin and hexarelin (GHRPs), CJC-1295 (long-acting GHRH), and MOTS-c (mitochondrial-derived peptide). All are supplied as lyophilized powder for in-vitro research only — not synthetic HGH.
