KPV
KPV (Lysine-Proline-Valine) is the C-terminal fragment of alpha-melanocyte-stimulating hormone (α-MSH), a potent anti-inflammatory peptide acting via melanocortin receptors (MC1R/MC3R). Orally stable, it’s researched for IBD, psoriasis, wounds, and allergies—reducing cytokines 50–80% without steroids’ sides. 3-amino-acid structure ensures gut penetration.
Key: MC1R agonism → ↓NF-κB, TNF-α, IL-6; ↑IL-10 resolution.
How It Works
- Cytokine Suppression: Blocks inflammatory cascades.
- Immune Balance: T-reg ↑, Th17 ↓.
- Barrier Repair: Tight junctions, mucosa integrity.
- Antimicrobial: Melanocortin pathways vs. pathogens.
Pharmacokinetics: Oral > subQ; half-life ~30min; systemic despite small size.
Research Evidence
| Application | Key Studies/Effects |
|---|---|
| IBD/Colitis | 80% colon damage reduction (mice, J Pharmacol Exp Ther 2010). |
| Psoriasis | Lesion clearance, TNF-α ↓70% (topical models). |
| Wounds | Healing 2x faster, ↓scarring (rat burns). |
| Allergies | Anaphylaxis prevention (MC1R KO studies). |
| Long-COVID | Cytokine storm analogs (prelim). |
- Human: Compassionate IBD use; oral capsules in trials.
Protocols (Research Contexts)
| Goal | Dose (mg/day) | Route/Frequency | Cycle |
|---|---|---|---|
| Gut Health (IBD) | 1–5mg | Oral daily | 4–12 weeks |
| Skin (Psoriasis) | 0.5–2mg | Oral + topical | 8 weeks |
| Wounds | 1–3mg | Oral + local | Until healed |
| Inflammation | 0.5–1mg | 2–3x/day | PRN |
- Stack: w/ BPC-157 (gut repair), GHK-Cu (skin).
- Form: Oral caps, nasal, cream.
Benefits Breakdown
- Gut Healing: UC/CD remission-like.
- Skin Conditions: Eczema, acne inflammation ↓.
- Allergy/Asthma: Mast cell stabilization.
- Post-Viral: Long-haul inflammation.
- Wellness: Systemic cytokine control.
Side Effects & Safety
| Common (Rare) | Notes | Mitigation |
|---|---|---|
| Mild nausea | MC1R pigmentation (low) | Dose-dependent |
| None major | Immunosuppression? (no) | Clean profile |
- Tox: LD50 >500mg/kg; pregnancy caution.
Comparisons
| Peptide | Anti-Inflam Target | Oral Stable? | Best For |

Status & Outlook
- Research Chemical: Oral formulations advancing.
- Trials: IBD Phase 2 (Integrative Peptides).
- UK: Research/clinic use.
