KPV
aka α-MSH (11-13)
A 3-amino-acid fragment of a natural hormone — acts like a chill pill for inflammation.
Technically · Tripeptide anti-inflammatory
In one sentence
A three-amino-acid fire extinguisher for inflammation — blocks the master switch (NFκB) that drives chronic disease.
— If BPC-157 is the construction crew, KPV is the firefighter. Skips repair, kills inflammation.
Half-life
Short (hours)
A few hours active — daily dosing.
Dosing
Daily SubQ; can stack with BPC-157/TB-500

What it is
A tiny three-amino-acid piece (Lys-Pro-Val) of your body's α-MSH hormone. It quiets one of the most important inflammation switches (NFκB). Used for autoimmune calming, gut healing, and skin inflammation. Strong anecdotal results in gut and skin issues.
The full technical answer
A three-amino-acid C-terminal fragment of α-melanocyte-stimulating hormone (Lys-Pro-Val). Acts as an NFκB blocker — the master inflammation switch. Used for autoimmune calming and gut healing.
How it works
Imagine inflammation as a fire alarm system, and NFκB is the master alarm switch. When NFκB flips on, dozens of inflammatory signals follow. KPV blocks that switch. The fire alarm doesn't go off, so the cascade of inflammation never starts.
The full technical answer
Blocks NFκB transcription factor activation, reducing pro-inflammatory cytokine cascades. Hunter Williams describes it as a "fire extinguisher" for inflammation versus BPC-157's "construction crew" repair.
What the research says
Animal and in-vitro data for inflammatory bowel disease, allergic inflammation, and autoimmune calming. Limited human RCTs. Strong anecdotal data in peptide community for gut and skin inflammation.

Common dosing ranges
- Range
- 200–500 mcg/day
- Frequency
- Daily SubQ; can stack with BPC-157/TB-500
- Duration
- 4–6 weeks on / 2–4 weeks off (Bachmeyer)
Sources: PubMed
How to take it
Practical guidance synthesized from clinical protocols, FDA labels, and clinician interviews. Always cross-check with a prescribing physician.
Best time of day
AM, daily. Some users dose twice daily (AM + PM) for active gut flares.
With food or fasted
Doesn't matter for SubQ. Oral KPV is also used for gut-specific effects — take fasted for gut benefit.
How long to cycle
4–6 weeks on, 2–4 weeks off (Bachmeyer protocol). Stack with BPC-157 + TB-500 in advanced gut/autoimmune cycles.
When to get off
End each cycle on schedule. Long-term continuous use in healthy people isn't studied.
Administration
Side effects
Common
- Generally well-tolerated
- Minimal reported
Serious / theoretical
- Long-term safety in healthy users not established

Notes
Hunter Williams rates KPV above BPC-157 specifically for inflammation. Stacks with BPC-157 + TB-500 in advanced gut/autoimmune protocols.
