Anti-inflammatory tripeptide for gut and skin · 500 mcg/day · 4–8 weeks
An anti-inflammatory tripeptide — the calming piece inside the KLOW blend, associated with gut and skin inflammation.
Volume pricing applied at checkout — free EU shipping on every order.
For laboratory and in vitro research use only. Not for human or veterinary use, and not for use in diagnostic procedures.
KPV is a three-amino-acid fragment (lysine-proline-valine) of the natural anti-inflammatory hormone alpha-MSH. It is associated with switching off inflammatory signalling (NF-κB) before it starts, while leaving normal immune function intact — which is why it features in gut and reactive-skin discussion.
PX1 Labs supplies KPV as a 10 mg lyophilized powder verified at 99%+ identity purity by HPLC, with identity confirmed by mass spectrometry. A lot-specific Certificate of Analysis is included with every order.
KPV is best known for inflammation — gut and skin. Here is what it is most associated with. (Supplied for laboratory research use only.)
Best known as an anti-inflammatory peptide that pre-empts the inflammation switch (NF-κB).
Its strongest research signal is gut inflammation, where inflamed cells actively take it up.
The calming component in skin blends like KLOW, for reactive or red skin.
Mechanistic and small-trial data (gut, skin); no large subcutaneous human trials.
KPV is a three-amino-acid fragment of alpha-MSH, a natural anti-inflammatory hormone. It is associated with blocking inflammatory genes (NF-κB) from switching on in the first place — different from drugs that block inflammation after it starts — while leaving normal immune signalling intact.
KPV's strongest evidence is mechanistic and from small trials, especially for gut inflammation (where inflamed cells actively absorb it) and topical/skin use. There is no large subcutaneous human trial. Not an approved medicine.

KPV passes the same five-stage PX1 quality process applied to every product: HPLC potency analysis, mass-spectrometry identity and purity confirmation, pH and stability validation, sterility and endotoxin (LAL) testing, and QC batch-consistency verification.
A lot-specific Certificate of Analysis ships with every order. The lot number printed on your vial matches the lot ID on the document, so the material on your bench can always be checked against the data on file.
Selected peer-reviewed literature on KPV (via PubMed), provided for educational context. A reference does not imply a clinical claim for PX1 Labs products.
A tripeptide fragment of alpha-MSH (Lys-Pro-Val), known as an anti-inflammatory peptide. It is the KPV in the KLOW blend.
As a 10 mg lyophilized powder with a lot-specific Certificate of Analysis confirming 99%+ identity purity by HPLC.
Every PX1 order ships within 24 hours with full analytical documentation in the box.
