Research Comparison
GHRP-6 vs Kisspeptin
A side-by-side research comparison of GHRP-6 and Kisspeptin drawn from Cobalt Peptides' peptide database records.
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.
Kisspeptin
Kisspeptin is a family of neuropeptides encoded by the KISS1 gene, acting as an upstream regulator of the reproductive axis through potent stimulation of gonadotropin-releasing hormone (GnRH) neurons. Several active isoforms are derived from a 145-amino acid precursor; kisspeptin-54 is the predominant circulating form and kisspeptin-10 the minimal fragment retaining full receptor binding. It is studied in reproductive endocrinology on that basis. Supplied strictly as a research compound for laboratory use.
