KPV
aka α-MSH (11-13)
What it is
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
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.
