Growth Hormone-Releasing Peptide 6 · His-DTrp-Ala-Trp-DPhe-Lys-NH₂

GHRP-6 is one of the original synthetic GHRPs, acting as a strong ghrelin receptor agonist. It produces robust GH release accompanied by significant appetite stimulation — a property that makes it both valuable for cachexia research and distinct from cleaner GHRPs like Ipamorelin. Research also shows cytoprotective and cardioprotective properties independent of GH secretion.

NNC 26-0161

Ipamorelin is a selective growth hormone secretagogue and ghrelin receptor agonist. Unlike other GHRPs, it stimulates GH release with high selectivity — producing minimal cortisol, ACTH, or prolactin elevation. It is among the most studied GHRPs for its clean GH pulse profile, making it a preferred research peptide for GH axis studies with reduced side effect concern.

CJC-1295 without DAC · Modified GRF 1-29

Mod GRF 1-29 is a modified version of GHRH(1-29) with four amino acid substitutions that increase stability and half-life without the DAC albumin-binding component. It produces a natural, pulsatile GH release and is commonly paired with GHRPs (like Ipamorelin) for a synergistic GH pulse. Its shorter duration preserves natural pituitary feedback mechanisms.
