Kisspeptin
KISS1 neuropeptide studied for GnRH regulation and reproductive-axis research.
Kisspeptin is the go-to research peptide for the reproductive and hormonal axis — the upstream switch that sits above the body's fertility and sex-hormone signalling. Encoded by the KISS1 gene, it triggers the release of GnRH, which in turn drives LH and FSH. Researchers study it around fertility, libido, and how the whole hormonal cascade is regulated.
Because it acts at the very top of the reproductive signalling chain, Kisspeptin is a key tool for studying the system as a whole.
