KPV price by research size
| Research size | Typical range / vial |
|---|---|
| 5 mg vial | $35 - $60 |
| 10 mg vial | $50 - $90 |
Ranges are typical research-market figures per vial for third-party-tested, 99%+ purity material with a COA on request. They are not a quote; current pricing - including bulk and subscription discounts - is shown in the order portal.
What you are paying for with KPV
KPV is the C-terminal tripeptide (lysine-proline-valine) of the alpha-melanocyte-stimulating hormone. In research it is studied because it retains anti-inflammatory activity associated with the parent hormone without the pigmentation effects, making it a clean model compound for inflammation studies. Because of that, the cost of KPV reflects more than raw material. KPV research focuses on its reported ability to enter cells and modulate inflammatory transcription pathways (such as NF-kB signaling), reducing pro-inflammatory cytokine output in models of gut and tissue inflammation.
What drives KPV pricing
Three things move the price of KPV most. First, vial size: KPV is cataloged in 5 mg vial, 10 mg vial, and a larger vial holds more peptide, so it costs more per unit even at the same per-mg rate. Second, purity and testing: genuine third-party verification to a 99%+ target with a Certificate of Analysis is a real production cost, and it is what makes a research result trustworthy. Third, quantity: ordering KPV in bulk or on a recurring research schedule lowers the effective per-vial cost.
Cost per milligram
Comparing peptides on price alone is misleading because vial sizes differ. The fair comparison is cost per milligram of verified peptide. When you evaluate KPV, divide the vial price by its milligram content and compare like-for-like against other 99%+ third-party-tested material - not against unverified powder that happens to be cheaper.
Getting the best value on KPV
KPV can be ordered as a one-time purchase or on a recurring research schedule (every 2 weeks, monthly, every 2 months, or every 3 months), and bulk or standing-order pricing is available for research programs. The best value is not the lowest sticker price - it is the lowest cost per milligram of documented, third-party-tested KPV, which is the standard every Peptides Factory Direct lot is held to.
Frequently asked questions
How much does KPV cost?
KPV typically ranges from $35 to $90 per vial at research-market pricing, depending on vial size. All Peptides Factory Direct KPV is third-party tested to a 99%+ purity target with a COA on request. Research use only.
Why does KPV pricing vary between suppliers?
Differences come down to purity and documentation. Material with genuine third-party COAs, lot tracking, and identity confirmation costs more to produce than unverified powder. The fair comparison is cost per milligram of verified peptide, not sticker price.
Is cheaper KPV a good deal?
Not if it lacks a Certificate of Analysis. Across the research-supply market the strongest trust signal is verifiable third-party purity testing. Unverified KPV can cost far more in failed experiments than the few dollars it saves.
Can I get bulk pricing on KPV?
Yes. KPV is available for one-time or recurring research orders, and bulk or standing-order pricing is available for research programs - note it on your order or open the portal.
