Buy KPV in the UK

KPV is the three-residue Lys-Pro-Val tail of α-MSH, offered as a 10mg freeze-dried vial or as capsules. Research use only.

from £21.992 options

  • In UK stock Sent from Britain
  • Leaves the same day When ordered before 2pm
  • Tracked shipping No charge over £75
  • Certificate of analysis Available on request

Prices for KPV start at £21.99 for the 10mg capsules, and all of it is already in British stock at diluents.co.uk rather than sourced to order. It is offered as capsules and vial. Order on a weekday before 2pm and the parcel leaves that day, tracked, in a box that gives no clue to its contents.

Because the parcel never leaves the country, nothing has to clear customs, no import charge falls due and nothing is held at a border. Each batch tests at ≥99% by HPLC, and a certificate of analysis for the stock you receive is available on request.

Tracked delivery costs £4.95, or nothing above £75. The ordering steps, one by one.

Which studies have looked at KPV?

All of the published work on KPV is pre-clinical, and no paper listed below is a trial in humans. Grouped by study model, here is what each paper examined:

In-vitro and animal studies

  • Melanocortin-derived tripeptide KPV has anti-inflammatory potential in murine models of inflammatory bowel disease, Mouse, DSS colitis and CD45RB-hi transfer colitis (PMID 18092346)
  • PepT1-mediated tripeptide KPV uptake reduces intestinal inflammation, Mouse, DSS- and TNBS-induced colitis (PMID 18061177)

Every entry names what a study examined. No entry reports an effect in a person, and nowhere does the site give instructions on how to use anything.

Buying KPV 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 KPV 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?

KPV 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.

5.00 mg/mlConcentration
0.100 mlHolds 0.5mg
10.0 unitsOn a U-100 syringe
50 mcgPer unit of that syringe

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 10mg 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.

mg/ml reached for each vial size and volume of water
Vial+ 1ml+ 2ml+ 3ml+ 5ml
10mg 10 mg/ml5 mg/ml3.33 mg/ml2 mg/ml

As a worked case, the 10mg vial with 2ml of bacteriostatic water comes to 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.

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.

KPV storage

Vial, still sealedKeep it dark, dry and cool; the freezer suits long-term storage best.
After mixingRefrigerate it upright and shaded. A mixed solution should never be frozen.
CapsulesNo refrigeration required; keep them sealed somewhere cool and dry.

What is its shelf life?

Typical keeping times for lyophilised peptides in general
ConditionTypical life
Unopened, in a −20 °C freezerYears. No other condition preserves a lyophilised peptide as well
Unopened, in a fridge at 2–8 °CMonths
Unopened, at room temperatureWeeks. It copes with the time in transit but should not be kept like this
Mixed, in the fridgeWeeks 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 frozenNot 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.

Here it is supplied strictly as an unlicensed compound for laboratory research use only. No UK marketing authorisation covers KPV 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.

Research use only. Diluent is not a pharmacy, and none of its compounds is a licensed medicine: everything is sold for laboratory research, with no dosage, protocol or administration guidance given. Not intended for human or veterinary use, or for use in food.

Questions about KPV

Which formats can I order?

Capsules, or a 10mg vial of freeze-dried powder.

What is KPV peptide?

The KPV 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 KPV?

In the UK, diluents.co.uk supplies KPV in one 10mg size only, as capsules and vials, priced from £21.99. The border and the clearance queue cause most peptide order delays, and a domestic shipment avoids both. The per-milligram cost falls as the size rises, from £2.20/mg on the smallest vial to £2.20/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. It is also a component of 1 other product in the range. 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 KPV cost?

Prices begin at £21.99 with the 10mg, £2.20 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 much bacteriostatic water goes into KPV?

That is up to you, since the volume added is what sets the strength. On the 10mg vial, 10 mg/ml comes from 1ml, 5 mg/ml from 2ml and 3.33 mg/ml from 3ml, while the 10mg of material inside does not change. Every one of these figures is a concentration and none is a dose.

How do you store KPV?

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.

Is KPV FDA approved?

Our KPV 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 KPV, 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.
