What is Kisspeptin-10?

Kisspeptin-10 is the shortest fully active fragment derived from the longer kisspeptin peptide encoded by the KISS1 gene, retaining the C-terminal sequence responsible for receptor engagement. Its discovery reshaped understanding of how the brain initiates the hormonal cascade behind puberty and fertility.

How it is understood to work

Kisspeptin-10 activates KISS1R, also called GPR54, on GnRH-producing neurons in the hypothalamus, triggering GnRH release, which in turn drives pituitary secretion of luteinizing hormone and follicle-stimulating hormone. This places it upstream of, and largely in control of, the entire hypothalamic-pituitary-gonadal signaling cascade in preclinical models.

Research status

Kisspeptin biology is studied in research on puberty onset, fertility, and HPG-axis regulation, and kisspeptin-based compounds, distinct formulations rather than necessarily this exact fragment, have been examined in human clinical studies of reproductive endocrinology. Kisspeptin-10 itself is used primarily as a laboratory tool for probing receptor activity rather than as an approved therapeutic.

Handling & storage

Supplied as a lyophilized powder; store unopened vials frozen and protected from light, and once reconstituted with bacteriostatic water, keep refrigerated and use within the timeframe appropriate to your study.

Concentration check: adding 2 ml of bacteriostatic water to one 10 mg vial gives 5 mg/ml. The Research Lab calculator in your dashboard works this out for any volume.

Questions

How does Kisspeptin-10 relate to the full-length kisspeptin peptide?

Kisspeptin-10 is the minimal C-terminal fragment of the longer, naturally processed kisspeptin peptide, and research indicates it retains essentially the same KISS1R receptor activity as the full-length form, which is why the short fragment is the more commonly used research tool.

Why is kisspeptin signaling considered a master regulator?

Because GnRH neurons sit downstream of kisspeptin/KISS1R signaling, kisspeptin effectively acts as the gatekeeper that times and drives the entire downstream cascade of LH and FSH release, making it a focal point for puberty and fertility research.

How much Kisspeptin-10 is in this kit?

10 vials of 10 mg each, so 100 mg in total. The lab testing section above shows what the brand’s tested vial actually contained.
