Kisspeptin is one of the most fundamental peptides within reproduction and hormone research. In this guide we explain, research-only, what Kisspeptin is, what role it plays in hormonal regulation and within which research themes it is studied — without any health or fertility claims.
Kisspeptin is a neuropeptide, encoded by the KISS1 gene, described in research as a central switch in the hypothalamic-pituitary-gonadal axis. It binds to the receptor KISS1R (GPR54). It is not a medicine and is offered for research only, ≥99% pure with a COA per batch.
What is Kisspeptin?
Kisspeptin is a neuropeptide encoded by the KISS1 gene that binds to the receptor KISS1R (GPR54). It is an endogenous signalling molecule that plays a key role in reproduction research. New to peptides? First read what peptides are.
Kisspeptin and the HPG axis
In research Kisspeptin is described as a central switch in the hypothalamic-pituitary-gonadal (HPG) axis, the hormonal system behind reproduction. It is a recurring subject in research into puberty, hormonal regulation and fertility. These descriptions come from preclinical and clinical research and are no proof of effect or usage advice.
Kisspeptin within the hormone category
Kisspeptin belongs to the peptides studied in hormone and fertility research. Within the same research category you will also find HCG and — via the growth-hormone axis — Tesamorelin. Browse the full hormones & fertility category to see the peptides side by side.
How is Kisspeptin reconstituted?
Kisspeptin is supplied as a lyophilised powder and reconstituted in the lab with bacteriostatic water. Determine the right ratio with the reconstitution calculator, or read how to reconstitute peptides.
Purity and documentation
Reproducible hormone research requires material with verified purity and full traceability. Every batch of Kisspeptin at Peptide Lab is tested by Janoshik Analytical at ≥99% purity by HPLC and mass spectrometry, with a public certificate per lot number.

Frequently asked questions about Kisspeptin
What is Kisspeptin?
Kisspeptin is a neuropeptide encoded by the KISS1 gene. It is studied within research into the hormonal regulation of reproduction and is not an approved medicine.
What role does Kisspeptin play in reproduction research?
In research Kisspeptin is described as a central switch in the hypothalamic-pituitary-gonadal (HPG) axis. It binds to the receptor KISS1R (GPR54). This concerns preclinical and clinical research; no health claims are attached to it.
Is Kisspeptin the same as a fertility medicine?
No. Kisspeptin is a research peptide offered for laboratory and research purposes only. It is not a medicine and not intended for human or animal consumption.
Is Kisspeptin pure at Peptide Lab?
Yes, Kisspeptin is lab-verified at ≥99% purity by HPLC and mass spectrometry, with a public Janoshik certificate per batch. For research purposes only.
