What has Kisspeptin-10 been studied for?
The record behind Kisspeptin-10 includes 2 human studies, which few compounds in this catalogue can say. Below is what each paper set out to examine, sorted by the model it ran in:
Human studies
- The effects of kisspeptin-10 on reproductive hormone release show sexual dimorphism in humans, Human, healthy men and women (PMID 21976724)
- Kisspeptin-10 is a potent stimulator of LH and increases pulse frequency in men, Human, healthy men (PMID 21632807)
Each line describes what a paper looked at. None of it reports an effect in a person, and no part of this site tells anyone how to use anything.
Where and how to buy Kisspeptin-10 in the UK
How do you order?
Pick a strength from the table, put it in the basket and check out. There is no account to set up. The confirmation reaches you straight away and the payment details follow by email, because no card is taken on the site.
Why does UK stock matter?
The Kisspeptin-10 you order leaves a warehouse in Britain. That means no customs step, no import charge and no days lost in transit from abroad. Before 2pm on a working day and it is collected that afternoon, tracked, in an outer box that gives nothing away.
What arrives in the box?
| Purity | ≥99%, by HPLC |
|---|---|
| Labelling | Compound, strength, format, purity, research-use statement and a batch number |
| Certificate of analysis | On request, matched to your batch number |
| Delivery | Tracked, UK only. £4.95, free over £75 |
| Returns | 14 days on unopened, sealed items, terms |
Reconstituting Kisspeptin-10
The vial arrives as a freeze-dried cake. It becomes a solution once bacteriostatic water goes in, and how much you add is what decides the strength of that solution. The quantity in the vial never changes, only the volume it is spread through.
What you see here are concentrations and volumes. Nothing on this site is dosage, protocol or administration guidance, and no number above is one either.
Loaded with 5mg and 2ml to start. Move either control and the numbers move with it. The full reconstitution calculator goes further, into syringe units, which water to pick and how long a mixed vial lasts.
| 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 |
Take the 5mg vial: 2ml of bacteriostatic water puts it at 2.5 mg/ml. The sum is the milligrams on the label over the millilitres you put in. Every figure here is a concentration. None of them is a dose, and this site carries no dosage, protocol or administration guidance at all.
Asked about mixing Kisspeptin-10
How to reconstitute kisspeptin?
Let it warm to room temperature, wipe the stopper, then send the bacteriostatic water down the side of the glass instead of onto the powder. Roll it until it clears; never shake it. Concentration follows from the volume you picked, so on 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.
How should it be handled?
- Let a refrigerated vial reach room temperature first.
- Wipe the stopper with an alcohol swab every time you go in.
- Aim the water at the glass wall so it runs down, not straight onto the cake.
- Roll it gently between your fingers. Shaking makes foam, and foam is damaged protein.
- Give it a few minutes to go into solution. Done properly it finishes clear.
Storing Kisspeptin-10
| Sealed vial | Somewhere cool, dry and dark. For anything long term, the freezer. |
|---|---|
| Once reconstituted | Fridge, standing upright, away from light. Never freeze it once mixed. |
How long does it keep?
| Stored as | Keeps for |
|---|---|
| Sealed, frozen at −20 °C | Years. Nothing holds a lyophilised peptide better than this |
| Sealed, refrigerated at 2–8 °C | Months |
| Sealed, at room temperature | Weeks. Fine while it is in the post, not a place to keep it |
| Reconstituted, refrigerated | Think weeks, not months. Four weeks is the number most people work to once bacteriostatic water is in, which is exactly what its preservative is there for |
| Reconstituted, frozen | Best avoided. Ice crystals tear at peptides, and every freeze–thaw round makes it worse |
Treat these as the usual numbers for lyophilised peptides, not a stability result measured on one batch. Cold and dry buys time; moisture, heat, light and being shaken about take it away. Ask and we will send the batch certificate of analysis.
Is Kisspeptin-10 legal in the UK?
We sell Kisspeptin-10 as an unlicensed research compound, for laboratory research use only. There is no UK marketing authorisation behind it, it is not a licensed medicine, and it is not for human use, veterinary use or food.
Nothing of this kind is a controlled drug, and selling it as laboratory material is lawful. Selling or marketing it for people to take is not. That line is the reason you will not find a dose, a protocol, a route, a frequency or a medical claim anywhere on this site, and the reason asking for one by email gets the same answer.
A few molecules in this range also appear inside a licensed medicine sold under a brand name. That authorisation belongs to the finished product it was granted for; it does not follow the molecule anywhere else. Full terms.
Kisspeptin-10 questions
What else is Kisspeptin-10 called?
Metastin came first, from the days when it was understood as a metastasis suppressor and nobody had yet connected it to GnRH. KP-10 is simply the shorthand everyone uses. Kisspeptin 45-54 is the most literal of the lot: it gives the position of these ten residues inside the 54-residue parent peptide. Whichever of the four you see, metastin, KP-10, kisspeptin 45-54 or Kisspeptin-10, the decapeptide behind it is this one.
What sizes do you stock?
Two vials, 5mg and 10mg.
What is kisspeptin?
We stock Kisspeptin-10 as an unlicensed research compound, sold for laboratory research and nothing else, assayed by HPLC at ≥99% purity. Its specification and the papers behind it are both further down this page.
Where can I buy Kisspeptin-10 in the UK?
Kisspeptin-10 is available in the UK from diluent.co.uk, from £17.99, 2 strengths, 5mg to 10mg, as vials. None of this is drop-shipped in from abroad. It comes off a shelf here, which is how it makes the same-day post. Buy bigger and the milligram gets cheaper: £3.10/mg at the keenest rate against £3.60/mg on the smallest vial, with every size carrying its own number. It turns up as freeze-dried powder, so the concentration is yours to set when you mix it. Get the order in before 2pm on a weekday and it leaves that day, tracked, plainly packaged. Batches go to a third-party lab and come back at ≥99% by HPLC, and the certificate for yours is there if you ask, see how to order.
How much does Kisspeptin-10 cost?
It starts at £17.99 for the 5mg, £3.60 per mg. 2 options in all, each with its own price and its own rate per milligram. Postage runs £4.95, and nothing at all above £75.
How long does kisspeptin last?
Still sealed and dry it will sit for years at −20 °C, months in a fridge at 2–8 °C, weeks at room temperature. Cold and dry is what buys the time. After mixing it goes in the fridge standing up, and four weeks is the figure most work to with bacteriostatic water. Never freeze it once mixed: ice crystals tear peptides apart and each freeze–thaw round does it again.
What purity is your Kisspeptin-10, and can I see a certificate?
≥99%, measured by HPLC. Quote the batch number on your label and we will send the certificate of analysis for that lot. If you would rather see where current stock sits before you commit, ask and we will tell you.
