Quickstart Overview

KPV is the C-terminal tripeptide (Lys-Pro-Val) of α-MSH and carries that hormone's anti-inflammatory activity in a small, stable fragment. It is studied in inflammatory bowel disease, dermal inflammation and mast-cell modulation, and works orally and topically as well as by injection.

Units assume a U-100 insulin syringe (100 units = 1 mL). Works orally (PepT1 uptake) and topically as well as subcutaneously.

Frequency: 1–2× daily

Reconstitution Steps

  1. 1Allow the lyophilized vial and bacteriostatic water to reach room temperature (~15 min).
  2. 2Swab both vial stoppers with a fresh 70% isopropyl alcohol pad and let them dry.
  3. 3Draw 2.0 mL of bacteriostatic water into a mixing syringe.
  4. 4Insert at an angle and let the water run slowly down the glass wall — never directly onto the powder.
  5. 5Gently swirl (do not shake) until the solution is completely clear.
  6. 6Label with date and concentration (mg/mL) and refrigerate at 2–8 °C immediately.

Supplies Needed

Planning example for a 8-week protocol at approximately 500 mcg per day.

Peptide (10 mg vials)
Estimate vials from total mass: 500 mcg/day × 56 days.
Bacteriostatic Water
One 10–30 mL vial typically covers a full cycle.
Insulin Syringes (U-100)
One per administration (29–31 G, 0.3–0.5 mL).
Alcohol Swabs
Two per administration (vial + site).
Sharps Container
Required for safe disposal.

Freeze/Thaw
Avoid repeat freeze–thaw cycles after reconstitution.

Important Notes

  • Among the best-tolerated compounds in the catalog.
  • Anti-inflammatory rather than regenerative — often paired with BPC-157 for repair.

How This Works

KPV inhibits NF-κB activation and reduces pro-inflammatory cytokines (IL-6, IL-8, TNF-α) in epithelial and immune cells, largely independent of melanocortin-receptor signalling. In the gut it is transported into colonic cells via the PepT1 transporter, where it dampens inflammation — the basis of its efficacy in colitis models. It also stabilises mast cells and shows antimicrobial activity.

Potential Benefits & Side Effects

Reported in research
  • Potent NF-κB-mediated anti-inflammatory activity
  • Reduced colitis severity in animal models
  • Mast-cell stabilisation and dermal anti-inflammatory effects
  • Oral and topical activity (PepT1 uptake)
  • Antimicrobial effects reported
Possible considerations
  • Very well tolerated in preclinical models
  • Mild injection-site irritation
  • Limited human clinical data
  • Effects are anti-inflammatory, not regenerative

Lifestyle Factors

  • Adequate hydration and 7–9 h of sleep are standard controls in most research protocols.
  • Consistent dose timing improves the reliability of any self-tracked endpoints.
  • Maintain a clean, sterile workflow for every draw to avoid contamination.

Injection Technique

  1. 1Wash hands, then prep the vial top and the target site with separate alcohol swabs.
  2. 2Pinch a subcutaneous skin fold (abdomen, ~2 inches from the navel) and insert at 45–90°.
  3. 3Depress the plunger slowly over 3–5 seconds, hold 5 seconds, then withdraw.
  4. 4Rotate sites each administration and dispose of the syringe in a sharps container.
