What KPV is
A small anti-inflammatory tripeptide derived from alpha-MSH studied for gut inflammation and skin, mostly in preclinical models.
KPV is the C-terminal tripeptide of the hormone alpha-MSH and carries much of its anti-inflammatory activity without pigmentation effects. Preclinical research has explored it for inflammatory bowel conditions and skin inflammation, where it appears to calm inflammatory signaling inside cells.
Mechanism: Enters cells and suppresses pro-inflammatory NF-kB signaling, reducing inflammatory cytokine production.
Regulatory history: Not FDA-approved. Removed from Category 2 (April 2026); PCAC voted 8 to 6 to recommend for compounding (July 2026); awaiting FDA rulemaking
How MHRA treats this kind of product
Licenses medicines for the UK market. A compound without a marketing authorisation is an unlicensed medicine, which can only lawfully be supplied for human use through a prescriber under the specials scheme, not sold as a research product.
The classification above is the The Longevity Archive reading of Medicines and Healthcare products Regulatory Agency listings for KPV at the reviewed date, not a legal opinion. Rules change, and importing, prescribing and possessing a compound can each be treated differently. Check the regulator directly before acting on anything here.
