What is Kisspeptin-10?
The ten residues come from kisspeptin and appear about as often under the names metastin or KP-10. It acts upstream of the release of gonadotropin-releasing hormone.

Buying Kisspeptin-10 in the UK: where and how
How does ordering work?
Choose a strength, add it to the basket and go through checkout; no account is needed. An order confirmation comes through at once, and since the site never takes a card, the payment details arrive separately by email.
What difference does UK stock make?
Your Kisspeptin-10 is sent from a warehouse in Britain, so it skips customs, attracts no import charge and loses no days travelling from overseas. A courier collects it the same afternoon if the order is in before 2pm on a working day; the parcel then travels tracked in a plain outer box.
What do you receive?
| Purity | ≥99%, measured by HPLC |
|---|---|
| Labelling | Compound name, strength, format, purity and a research-use statement |
| Certificate of analysis | Available on request for the stock you receive |

Kisspeptin-10 reconstitution
What ships is a dry, freeze-dried cake, and bacteriostatic water is what turns it into a solution. The volume you choose sets how strong that solution ends up. Water only spreads the contents out; it never adds to or takes from the milligrams sealed in the vial.
The figures above are volumes and concentrations of a solution; none of them is a dose, and no guidance on dosing, protocols or administration is given on this site.
The figures open on the 5mg vial with 2ml added, and they update as soon as either control changes. For the syringe-scale conversion, a comparison of the waters and the keeping time of a mixed vial, use the full reconstitution calculator.
| Vial | + 1ml | + 2ml | + 3ml | + 5ml |
|---|---|---|---|---|
| 5mg | 5 mg/ml | 2.5 mg/ml | 1.67 mg/ml | 1 mg/ml |
| 10mg | 10 mg/ml | 5 mg/ml | 3.33 mg/ml | 2 mg/ml |
As a worked case, the 5mg vial with 2ml of bacteriostatic water comes to 2.5 mg/ml, which is simply the label milligrams divided by the millilitres added. Every number in the table is the concentration of a solution, never a dose. Dosage, protocol and administration guidance appear nowhere on this site.
Asked about mixing Kisspeptin-10
How to reconstitute kisspeptin?
Once the vial is at room temperature and the stopper has been swabbed, the bacteriostatic water goes in along the glass wall, away from the powder. Keep rolling until the solution is clear, and do not shake. The volume chosen fixes the concentration; for the 5mg vial, 1ml gives 5 mg/ml, 2ml gives 2.5 mg/ml, 3ml gives 1.67 mg/ml, 5ml gives 1 mg/ml.
What care does the vial need?
- A chilled vial should warm to room temperature first.
- Before every entry through the stopper, clean it with an alcohol swab.
- Let the water run down the inside wall of the glass; never squirt it onto the cake.
- Roll, never shake: foam means protein has been damaged, and rolling between the fingers avoids it.
- Expect a few minutes before it dissolves fully; a correctly mixed vial ends up clear.
Kisspeptin-10 storage
| Vial, still sealed | Keep it dark, dry and cool; the freezer suits long-term storage best. |
|---|---|
| After mixing | Refrigerate it upright and shaded. A mixed solution should never be frozen. |
What is its shelf life?
| Condition | Typical life |
|---|---|
| Unopened, in a −20 °C freezer | Years. No other condition preserves a lyophilised peptide as well |
| Unopened, in a fridge at 2–8 °C | Months |
| Unopened, at room temperature | Weeks. It copes with the time in transit but should not be kept like this |
| Mixed, in the fridge | Weeks rather than months. With bacteriostatic water added, the usual working figure is four weeks, and making that possible is the job of its preservative |
| Mixed, then frozen | Not recommended. Peptides are torn by ice crystals, and each freeze–thaw cycle compounds the damage |
These are the standard figures for lyophilised peptides in general; no stability study on a single batch produced them. Time is gained by keeping it cold and dry, and lost to damp, warmth, light and rough handling. A certificate of analysis is available on request.
Is Kisspeptin-10 legal in the UK?
Here it is supplied strictly as an unlicensed compound for laboratory research use only. No UK marketing authorisation covers Kisspeptin-10 and it is not a licensed medicine, nor is it intended for human or veterinary use, or for food.
Compounds of this kind are not controlled drugs, and they can lawfully be sold as laboratory material; it is selling or marketing them for use by people that the law does not allow. That boundary is why this site carries no dose, protocol, route, frequency or medical claim, and why an emailed request for one is declined as well.
Some molecules in this range are also present in a licensed medicine marketed under a brand name. Its authorisation covers only the finished product for which it was granted, not the molecule in any other setting. Read the full terms.
Questions about Kisspeptin-10
Which other names does Kisspeptin-10 go by?
The oldest is metastin, a name from when the peptide was seen as a metastasis suppressor, before anyone had linked it to GnRH. KP-10 is just the common abbreviation. Kisspeptin 45-54 is the most exact, since it states where these ten residues sit within the 54-residue parent peptide. So metastin, KP-10, kisspeptin 45-54 and Kisspeptin-10 all refer to this same decapeptide.
What vial sizes does it come in?
Vials of 5mg or 10mg.
What is kisspeptin?
The Kisspeptin-10 sold here is an unlicensed research compound, supplied for laboratory research only, and HPLC assay puts it at ≥99% purity. Further down this page you will find the full specification alongside the published studies.
Where in the UK can I buy Kisspeptin-10?
In the UK, diluents.co.uk supplies Kisspeptin-10 in 2 strengths from 5mg up to 10mg, as vials, priced from £17.99. Nothing is drop-shipped from overseas: each order is picked from a UK shelf, and that is what lets it catch same-day dispatch. The per-milligram cost falls as the size rises, from £3.60/mg on the smallest vial to £3.10/mg at the best rate, and each size lists its own figure. Because it is supplied as freeze-dried powder, the concentration is whatever you choose when it is mixed. Orders placed before 2pm on a weekday go out the same day, tracked and in plain packaging. Each batch goes through third-party lab testing and returns an HPLC result of ≥99%; the certificate covering yours is available on request, and for the steps, see how to order.
What does Kisspeptin-10 cost?
Prices begin at £17.99 with the 5mg, £3.60 a milligram. Each of the 2 options carries a separate price and a separate per-milligram rate. Delivery costs £4.95, and above £75 there is no charge at all.
How long does kisspeptin last?
Unopened and dry, it lasts for years in a freezer at −20 °C, for months refrigerated at 2–8 °C and for weeks at room temperature; the colder and drier the conditions, the longer it keeps. Once mixed with bacteriostatic water it belongs upright in the fridge, where four weeks is the usual working figure. A mixed vial must never be frozen, because ice crystals rip peptides apart and every freeze–thaw cycle repeats the damage.
What is the legal status of Kisspeptin-10 in the UK?
Our Kisspeptin-10 is supplied strictly for laboratory research, as an unlicensed research compound and for no other purpose. No UK marketing authorisation covers the product we sell, so it is not a licensed medicine; it is also not for human or veterinary use. Nor are we a pharmacy.
Can I see a certificate for your Kisspeptin-10, and what purity is it?
Yes. HPLC puts it at ≥99%, and on request we send the certificate of analysis that matches the material in your order. To check where current stock stands before you place an order, just ask and we will tell you.
