KPV 5mg · Lysine-Proline-Valine (α-MSH C-terminal tripeptide) · 98.9% Purity

What is KPV?

KPV (Lysine-Proline-Valine) is the C-terminal tripeptide fragment of α-MSH (alpha-melanocyte stimulating hormone). Despite being just three amino acids long, KPV retains the anti-inflammatory action of the parent molecule via NF-κB suppression — making it one of the most cost-effective anti-inflammatory peptides in recovery and immune research.

What is KPV used for?

Most-studied applications: ulcerative colitis and IBD recovery, atopic dermatitis (skin inflammation), wound healing, and adjunctive immune modulation. Frequently stacked with BPC-157 for compound gut-repair protocols and with LL-37 for antimicrobial + anti-inflammatory research. Pairs naturally with Thymosin Alpha-1 for systemic immune stacks.

How does it work?

C-terminal tripeptide fragment of α-MSH (alpha-melanocyte stimulating hormone); anti-inflammatory action via NF-κB suppression in gut, skin, and joints. Read our complete research hub for the full literature review, or jump to our best peptides for recovery article for comparator molecules.

Why this listing?

KPV is unique in the peptide world — its small size means it survives oral administration to a meaningful degree, making both injectable and oral capsule research valid. Apex Research's batch KPV-2604-C tested 98.9% pure by HPLC.

How Peptide.best sources and verifies KPV

Every KPV listing on Peptide.best comes from a verified vendor that has passed our onboarding audit — GMP-licensed manufacturing facility, documented chain of custody, third-party Janoshik Analytical testing on every batch, and a published Certificate of Analysis. Apex Research (the seller on this listing) currently maintains a 4.9-star average across all their products. Compare the five live offers on the right side of this page — Peptide.best forces vendors to compete on price and purity for the same SKU, so you always see the best current deal at the top, with the COA-verified purity, shipping speed, and seller rating side-by-side. Looking for alternatives in the same recovery space? BPC-157 and the other peptides listed under our Recovery category are the most commonly compared alternatives.

Standard research dosing

Subcutaneous: 200–500 mcg, 1–2x daily. Oral capsule: 500 mcg, 2x daily for GI research. Topical: 0.01–0.1% in carrier base for skin research. Typical cycle: 4–8 weeks.

Reconstitution

This product ships as lyophilized powder. Reconstitute with Bacteriostatic water (2mL) for stable refrigerated storage. Once reconstituted, use within 30 days; keep at 2–8°C.

Protocol notes

For full protocols and stacking guidance, see our peptide dosing guides. Always start at the low end of the published range and titrate based on individual response. Half-life (~2 hours systemic) determines dosing frequency.

Reported side effects

Exceptionally clean profile — no significant adverse events reported in published work. Occasional mild GI upset with oral administration.

Contraindications

Do not use during pregnancy or lactation. Do not combine with other peptides without reviewing pharmacology. Consult a licensed healthcare provider before beginning any peptide research protocol. Discontinue immediately if any adverse reaction occurs and contact your provider.

Drug interactions

Limited interaction data exists for most research peptides. Be especially cautious when combining with prescription medications affecting the same physiological pathway as KPV (recovery pathway).

Certificate of Analysis

Every batch of KPV sold on Peptide.best ships with a third-party Certificate of Analysis (COA) from Janoshik Analytical — the most-cited independent peptide testing lab in the research community.

Q: Is KPV legal to purchase?

A: KPV is sold on Peptide.best for research purposes where applicable. Legal status varies by jurisdiction. See our disclaimer for full details.

Q: How long until I see effects?

A: Timing depends on protocol, dose, and individual response. Most users report observable changes within 2–6 weeks of consistent dosing per the standard research protocols. See the Dosing & Protocol tab.

Q: Can I stack KPV with other peptides?

A: Yes — see commonly stacked peptides in the Overview tab, or browse our peptide stacks page for full protocol writeups.

Q: Why is the price lower than pharmacy retail or other research sites?

A: Peptide.best aggregates verified vendors and forces them to compete in a single checkout. Vendors save on customer-acquisition cost; the savings pass to you. Every batch is still 3rd-party COA tested.
