KPV for Research

What is 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.

How KPV works (research mechanism)

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.

Primary research applications

Gut inflammation models

KPV is studied in models relevant to inflammatory bowel research (such as colitis and Crohn-type models) where epithelial inflammation is the variable.

General anti-inflammatory research

It is used as a model peptide for systemic and tissue inflammation studies with minimal off-target signaling.

Immune-modulation research

Its melanocortin lineage makes it relevant to immune-signaling investigations.

Research dosing reference

Research references commonly cite 500-1,000 mcg daily across a 4-12 week study window. Reference values only - not dosing for any subject.

Reconstitution & handling

KPV ships as a lyophilized (freeze-dried) powder and must be reconstituted before use in any liquid research model. Allow the vial to reach room temperature, swab the stopper, then add bacteriostatic water slowly down the inside wall of the vial - never spray it directly onto the powder. Swirl gently until dissolved; do not shake, as shaking foams the solution and stresses the peptide. The volume of water you add sets the concentration: a 5 mg vial reconstituted with 2 mL yields 2,500 mcg/mL, so 0.1 mL measures 250 mcg. A correctly reconstituted KPV solution is clear; discard if it is cloudy or shows particulate.

Storage & stability

Store un-reconstituted KPV vials refrigerated and protected from light for long-term stability; the lyophilized form is robust and tolerates shipping. After reconstitution, refrigerate at 2-8C, keep away from light, and use within the typical research window of roughly two to four weeks. The benzyl alcohol in bacteriostatic water helps inhibit microbial growth across that period. Always label reconstituted vials with the concentration and date.

Common research pairings

In healing research KPV is sometimes studied alongside BPC-157 for combined repair-and-inflammation models.

How KPV compares

Unlike BPC-157 and TB-500, which are studied for structural tissue repair, KPV is studied specifically for inflammatory signaling, making it complementary rather than competitive.

Safety & research considerations

KPV is a research chemical with no approved human use. For in-vitro and laboratory research only.

KPV research reference data

The figures below are reference values compiled from the research literature for laboratory study design only. They are not instructions for any living subject. See the full KPV research reference for complete detail and citations.

Half-life and exposure. Short acting

Pharmacokinetics (research reference). Human pharmacokinetics are not standardized. Treat exposure as short acting unless compound-specific data or formal formulation labeling indicates otherwise.

Reconstitution and concentration by vial size

Research timing. Daily or split AM/PM depending on protocol objective. Local versus systemic placement should be determined by research design and clinician preference.

Dose-escalation reference. Start with conservative exposure to evaluate injection-site tolerance and systemic response before increasing or layering additional repair agents.

Monitoring in research models. Monitor injection tolerance, GI response, fatigue, headache, or unexpected immune/inflammatory changes.

Reassessment cadence. Short-course, tightly controlled protocols are preferred. Reassess immune/inflammatory response before repeating or extending, especially with irritating or immune-active peptides.

Stacking notes (research). Pairs with BPC/TB/GHK-Cu when inflammation is part of the repair target; avoid over-stacking anti-inflammatory agents initially.

Sourcing, purity & Certificate of Analysis

Every lot of KPV sold by Peptides Factory Direct is third-party tested to a 99%+ purity target, with identity confirmed by mass spectrometry and purity quantified by HPLC. A Certificate of Analysis (COA) documenting these results is available on request and ties each vial to a tracked lot. Material ships nationwide to all 50 US states with cold-chain handling where appropriate and fast domestic dispatch. This documentation is what separates research-grade KPV from unverified material - quality is established before the vial ever reaches your lab.

How to order KPV for research

KPV can be ordered through the Peptides Factory Direct research portal as a one-time purchase or on a recurring research schedule (every 2 weeks, monthly, every 2 months, or every 3 months). Checkout requires confirming you are 21 or older, purchasing for laboratory research only, and that the product is not for human or animal consumption. Bulk and standing-order pricing is available - note it in your order. Open the order portal to view current research sizes and pricing.
