KPV (Lysine-Proline-Valine Tripeptide)

Category: Healing & Recovery. Status: Research compound.

A tripeptide derived from alpha-MSH with potent anti-inflammatory properties. Shows promise for gut inflammation, skin conditions, and immune modulation without melanogenic effects.

How it works

Inhibits NF-kB signaling pathway, reduces pro-inflammatory cytokine production (TNF-α, IL-6), and modulates immune cell activation.

Key facts

  • Molecular weight: 342.43 Da

Community reviews of KPV

Rated 4.7 out of 5 from 15 community reviews by ResearchSafe members.

  • lab_notes_tom rated it 4/5 - Worth adding to the protocol: KPV has been a worthwhile addition. I am data-driven and tracked relevant markers before, during, and after. The improvement is measurable and correlates with the intervention timeline. What sets this apart from some compounds I have tried is the consistency. Benefits did not fluctuate wildly or disappear. They built up and maintained. That gives me confidence in the mechanism. Tolerance has been excellent. Nothing in my bloodwork or subjective experience raised any flags. This is the kind of compound that does its job quietly without causing problems. Exactly what you want.
  • medic_elle rated it 5/5 - Colitis symptoms eased on sublingual: Colitis, and sublingual KPV at 500mcg a day eased my symptoms over about two weeks. Gentle, no real side effects for me going sublingual. I run it alongside BPC during flares. The data is thin so I treat it as experimental, but the real-world relief has been consistent across a couple cycles.
  • gutcheck_raj rated it 5/5 - Sleeper hit of my gut protocol: KPV has been the surprise of my gut stack. Ran it with oral BPC-157 during a flare, 500mcg twice a day, and within about two weeks the inflammation and urgency calmed more than BPC alone ever managed. It is gentle, no tanning or appetite weirdness like the melanocortin peptides. Only downside is finding a vendor that will show a COA for the exact lot.
  • labrat_sasha rated it 5/5 - Psoriasis patches less scaly: Topical KPV on some psoriasis patches, less scaling and redness by week 1-2 and my skin barrier seemed to settle. I like that it targets inflammation without the tanning or appetite effects of the full melanocortin peptides. Not a cure but a genuinely useful, low-risk add for skin.
  • cold_chain_carl rated it 5/5 - Noticed clear benefits within weeks: Added KPV to my protocol about 4 months ago and it has earned its place. The benefits became noticeable around week 2-3 and have been consistent since. What I appreciate about this compound is the predictability. It does what the research suggests it should do, at roughly the timeline you would expect. No surprises, no dramatic swings, just steady improvement. No notable side effects to report at my dose. Sourcing is always the challenge with research compounds, insist on third-party testing. Storage and reconstitution per standard protocols. Plan to continue.
  • pulsatile_pat rated it 5/5 - Genuinely effective after 2 months: Been using KPV for about 2 months and the results are clear. Not overnight dramatic, but a steady, consistent improvement that became undeniable by the end of the first month. The mechanism makes sense based on what I have read in the literature, and my subjective experience matches the expected timeline. Benefits built gradually and plateaued at a good level. Side effects were minimal to none at the dose I used. Followed proper protocols for sourcing, storage, and administration. Would recommend to others who have done their research and have realistic expectations.
