KPV

Updated May 29, 2026

Primary Benefits

  • Supports a healthy inflammatory response
  • Improves gut lining integrity and intestinal barrier function
  • Helps modulate immune signaling in gut and skin tissues
  • Supports skin comfort and tissue repair in inflammatory-stress models
  • Commonly used for gut inflammation, skin irritation, and to support gut barrier-defense

Mechanism of Action

KPV (Lys-Pro-Val) is the C-terminal tripeptide sequence of alpha-melanocyte-stimulating hormone (alpha-MSH), a naturally occurring immunomodulatory peptide. In intestinal research models, KPV is transported into epithelial and immune cells through the PepT1 peptide transporter, where it has been shown to reduce activation of NF-kB and MAPK inflammatory signaling pathways and lower downstream inflammatory cytokine activity such as IL-8. KPV and related alpha-MSH peptides have also been studied for antimicrobial activity against organisms such as Staphylococcus aureus and Candida albicans, which may help explain research interest in barrier tissues such as the gut and skin.

Dosing & Protocol

Subcutaneous (SQ) Injection (preferred)

Reconstitution:

-10 mg vial → 2.0 ml bacteriostatic water

Daily Dose:

-250–500 mcg (5–10 units)

Cycle:

-5 days on / 2 days off; 4–8 weeks or as directed by your healthcare provider

Timing:

-Patient Preference. Morning most common. Take at approximately the same time each day for consistent results

Potential Side Effects

  • Injection-site redness, tenderness, itching, or mild swelling
  • Headache, nausea, lightheadedness, or fatigue (uncommon)
  • Temporary digestive changes such as bloating or changes in stool pattern
  • Skin flushing, rash, or sensitivity reactions in susceptible individuals (rare)
  • Rare: allergic reaction or worsening symptoms; discontinue and seek medical guidance if concerning reactions occur

If side effects occur, users commonly reduce dose or discontinue use and consult a healthcare professional.

Common Stacks

  • With BPC-157: For gut lining, connective tissue, and inflammatory recovery support
  • With TB-500: For broader soft-tissue recovery and mobility protocols
  • With GHK-Cu: For skin, tissue repair, and cosmetic or wound-healing support
  • With LL-37: For research protocols focused on barrier defense, microbiome balance, and immune support; introduce cautiously and one at a time

Notes

  • Injection is subcutaneous into the lower abdomen or another standard SQ site (such as the outer thigh or upper buttock).
  • KPV is a research peptide with most evidence coming from cell and animal models; human clinical dosing data are limited.
  • Start at the lower end of the range when assessing tolerance, especially in sensitive individuals.
  • Lyophilized (dry) KPV vials should be stored in the freezer.
  • After reconstitution, store in the refrigerator and use within 45 days unless the product label or protocol says otherwise.
  • Users who are pregnant or breastfeeding, have an active infection, immune disorder, or are using prescription immunomodulating medications should consult a healthcare professional before use.
