Kisspeptin is the master upstream regulator of GnRH in reproductive neuroendocrine research. Full Kiwi Peps kisspeptin peptide research profile inside.
The kisspeptin peptide family (KISS1-gene-derived, most commonly supplied as Kisspeptin-10 in research vials) activates GPR54 (KISS1R) and sits upstream of GnRH neurons. In reproductive-neuroendocrine research, kisspeptin is the canonical reference compound for GnRH-axis stimulation studies in animal models. The amidated C-terminus is required for GPR54 activation, which is why analytical documentation must confirm the terminal amide.
