Research Comparison
GHRP-2 vs GHRP-6
A side-by-side research comparison of GHRP-2 and GHRP-6 drawn from Cobalt Peptides' peptide database records.
GHRP-2
GHRP-2 (Growth Hormone Releasing Peptide-2) is a synthetic hexapeptide belonging to the growth hormone secretagogue (GHS) class. It stimulates the release of endogenous growth hormone (GH) primarily through activation of the ghrelin receptor (GHS-R1a) in the hypothalamus and pituitary. Unlike GHRH analogs, GHRP-2 acts via a distinct pathway, making it highly synergistic when combined with GHRH-based peptides. It is widely used in research to investigate growth hormone pulsatility, appetite signalling, and metabolic regulation.
GHRP-6
GHRP-6 (Growth Hormone Releasing Peptide-6) is a synthetic hexapeptide belonging to the growth hormone secretagogue (GHS) class. It stimulates endogenous growth hormone (GH) release via activation of the ghrelin receptor (GHS-R1a) in the hypothalamus and anterior pituitary. As one of the earliest developed GHRPs, GHRP-6 is well-characterised and widely used in research investigating GH pulsatility, appetite signalling, and metabolic regulation. It is known for its strong orexigenic (appetite-stimulating) effects in addition to GH release.
