What is Kisspeptin-10, and what is it used for?
Kisspeptin-10 is also listed and searched as Kisspeptin, Kisspeptin peptide, Kp-10. They all mean the same compound. Supplier lists write it as Kisspeptin-10 peptides or peptide Kisspeptin-10 as well; every one of those is this record. A name is not a test, which is why the lot record further down counts for more than the wording on a label.
Chemically: molecular formula C63H83N17O14, average mass 1302.4 g/mol (PubChem CID 25240297). Those figures are what the identity test on a certificate is read against.

Kisspeptin-10 nasal spray, capsules or oral form? What this vial is, and is not
Search results for Kisspeptin-10 also show nasal spray, capsules, oral form products, under listing titles such as kisspeptin nasal spray, kisspeptin-10 nasal spray, kisspeptin pills, kisspeptin-10 pills, kisspeptin-10 tablets, can kisspeptin be taken orally. Those are finished consumer goods made and marketed by other companies, and none of them is what this page sells. This record is freeze-dried Kisspeptin-10 in a sealed glass vial, 5mg and 10mg, with a lot certificate, supplied for laboratory work. Its certificate describes that powder, not a capsule, spray or cream, which carry other ingredients and sit under different rules.

The Kisspeptin-10 certificate: lot, purity, identity, and how to verify it
A certificate answers identity, purity and net content as three separate questions, each with the method that produced it and the date it was run, how to read one covers what each field does and does not cover. For Kisspeptin-10 that means a mass spectrum landing on 1,302.4 g/mol for C63H83N17O14, the figure published against PubChem CID 25240297. The cataloged form is Kisspeptin-10, and the identity test resolves to that rather than to a related molecule with a similar name.

Testing by Kovera Labs. Every batch tested on or after October 1, 2026 includes endotoxin, sterility and fentanyl screening, in addition to identity, purity and net content. Open the report, then confirm it on the issuing laboratory's own site. If the identifier does not resolve there, or resolves to a different lot than the one printed on your vial, the document is worthless however convincing it looks.

The lot number on the certificate must match the lot printed on the vial you received. That match is the only thing tying the document to your material. Net content is reported separately from purity, because a vial can be highly pure and still hold less material than its label states.

Kisspeptin-10 research: what the published studies examine
Status: No FDA-approved application. This compound is sold as laboratory material. Where research on it has been published, it sits at the animal, cell or early-human stage, and this record does not summarize what it found. A supplier is not a neutral judge of evidence about its own catalog.
Kisspeptin-10 is the ten-building-block tail of kisspeptin, and it works fully on KISS1R, the receptor once called GPR54. The history is unusual. The gene was first found as something that suppresses cancer spreading, which is where the name metastin comes from, and its role in reproduction only emerged in 2003, when people with broken versions of the receptor turned out to never start puberty, a pattern reproduced in mice bred without it. Mechanically it sits at the very top of the reproductive chain.
The receptor is on the GnRH nerve cells themselves, so kisspeptin acts directly on them to trigger GnRH release, which in turn drives LH and FSH out of the pituitary. That puts it above the whole cascade rather than inside it.
| Reported observation | Model | Source |
|---|---|---|
| The receptor was shown to sit on GnRH nerve cells in the mouse hypothalamus. In mice bred without the receptor those nerve cells looked normal and their connections were intact, showing that the reproductive failure comes from GnRH not being released rather than from cells failing to develop. Amounts of kisspeptin that produced strong LH and FSH release in normal mice did nothing in the knockouts, so the effect runs only through that receptor. Given into the brain fluid of sheep, it produced measurable GnRH release with a matching rise in blood LH. | mouse hypothalamus, GPR54 knockout mice, and direct GnRH measurement in sheep | Messager and colleagues, Kisspeptin directly stimulates gonadotropin-releasing hormone release via G protein-coupled receptor 54, Proceedings of the National Academy of Sciences (2005)The knockout comparison is what makes this decisive: same dose, robust response in wild-type, nothing in the knockout. |
| A review recording that broken versions of the receptor are linked to puberty never starting in humans, that kisspeptin-10 strongly stimulates the reproductive hormone axis across several species and routes, and that the kisspeptin system acts as a gatekeeper on GnRH nerve cells, controlled by sex hormones and probably by the body’s metabolic state. | review of human genetics, animal and species-comparative work | Tena-Sempere, GPR54 and kisspeptin in reproduction, Human Reproduction Update (2006) |
Open questions. The receptor biology here is exceptionally well established. Human genetics, knockout mice and direct measurement of the hormone all point the same way, which is rare in this catalog. The gaps are elsewhere. Kisspeptin-10 clears from the blood quickly, much faster than the longer forms of kisspeptin, so what happens with steady rather than one-off exposure is a separate question from what the short studies show.
The reproductive system runs on feedback, and steady stimulation of receptors in systems like that commonly causes them to stop responding rather than to keep firing, which is the very principle some fertility drugs are used to exploit. Whether that applies here under steady exposure is not settled by the acute work above. The system is also governed by sex hormones and by metabolic state, so effects are unlikely to be the same across different conditions.
No kisspeptin product is approved for anything, and the human work that exists is mostly investigation of how the body works rather than treatment trials.
Each row above describes an observation in the stated model. None of it describes what Kisspeptin-10 would do in a person or an animal outside that model, and none of it is a recommendation to use it for anything.
How to store Kisspeptin-10: refrigeration and shelf life
Keep the sealed vial cold and out of the light and it stays as it left the lab. Once it is mixed into a solution, how long it holds up depends on the compound, what it was mixed with, how strong the solution is and how cold it is kept — too many variables for anyone to print one shelf life on a label. So laboratories write the date on whatever they prepare and keep their own record of it.
For solution preparation arithmetic on the bench, concentration, per-graduation values and molarity, use the vial concentration calculator, which opens with the Kisspeptin-10 sizes stocked here already loaded. It covers laboratory measurement only and contains no administration guidance.
