What Is Kisspeptin?

Kisspeptin is a naturally occurring peptide central to the hypothalamic-pituitary-gonadal (HPG) axis, studied for its role in initiating gonadotropin-releasing hormone (GnRH) release. Human studies have used two variants — kisspeptin-10 and kisspeptin-54 — and findings are not automatically interchangeable between them, an important distinction for anyone reviewing the primary literature.

Benefits and Uses

Available research on kisspeptin spans several areas of reproductive-endocrinology interest:

Reproductive axis regulation. Kisspeptin-GPR54 signaling is established as essential for preovulatory GnRH neuron activation and the luteinizing hormone surge.
Hypogonadotropic hypogonadism research. Loss-of-function studies in the kisspeptin/GPR54 pathway are foundational to understanding this condition’s mechanism.
Extending beyond reproduction. Some preclinical, non-reproductive research has explored kisspeptin signaling outside the HPG axis — this line of research is not human-validated and should not be blended with the reproductive-axis findings above.

How It Works

Kisspeptin binds GPR54 (KISS1R) on GnRH neurons, triggering the release of GnRH, which in turn drives luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion from the pituitary. This mechanism was clarified through both human genetic studies and animal-model research establishing kisspeptin/GPR54 signaling as necessary for normal pubertal onset and reproductive function.

Handling

Standard peptide storage and reconstitution practices apply. A reconstitution reference tool is available to convert a target concentration into a working solution volume. For research applications, CellGenic provides a reconstitution calculator that converts a professionally determined dose into the corresponding volume, with free access for all visitors.

FAQ

What is kisspeptin?

Kisspeptin is a naturally occurring peptide involved in the regulation of the hypothalamic-pituitary-gonadal (HPG) axis. It is studied for its role in stimulating gonadotropin-releasing hormone (GnRH) signaling.

How does kisspeptin work?

Kisspeptin binds to the KISS1R, also known as GPR54, on GnRH neurons. This signaling can stimulate GnRH release, which regulates downstream luteinizing hormone (LH) and follicle-stimulating hormone (FSH) secretion.

What is kisspeptin studied for?

Research involving kisspeptin includes reproductive-axis regulation, GnRH signaling, puberty biology, and mechanisms associated with hypogonadotropic hypogonadism. Additional preclinical research has examined kisspeptin signaling outside the reproductive system.

What is the difference between kisspeptin-10 and kisspeptin-54?

Kisspeptin-10 and kisspeptin-54 are different peptide variants derived from the KISS1 gene product. Findings involving one variant should not automatically be assumed to apply to the other, so research documentation should clearly identify the peptide variant being studied.

What is KISS1R or GPR54?

KISS1R, also known as GPR54, is the receptor through which kisspeptin exerts its primary signaling activity. It is expressed on GnRH neurons and plays an important role in reproductive-axis regulation.

Is kisspeptin approved for human use?

CellGenic kisspeptin is supplied strictly as a research chemical for laboratory and in vitro experimentation. It is not marketed or supplied by CellGenic as a drug, medical treatment, food, or cosmetic.
