The KLOW blend is a four-peptide research formulation that extends the GLOW blend by adding KPV — a tripeptide fragment of alpha-melanocyte-stimulating hormone (α-MSH). KPV is studied for anti-inflammatory and epithelial integrity signaling, making KLOW the preferred choice for research protocols where inflammation modulation is a primary variable alongside tissue repair. Typically supplied as an 80mg combined vial.
What KPV adds to GLOW
KPV (Lys-Pro-Val) is the C-terminal tripeptide of α-MSH. It is studied in research contexts for its interaction with melanocortin receptors, particularly MC1R, which plays a role in inflammatory signaling modulation. In the KLOW blend, KPV provides a dedicated anti-inflammatory research dimension that the GLOW blend does not include. This makes KLOW particularly relevant for models of chronic inflammation, gut inflammation, and skin-related inflammatory pathways.
KLOW vs GLOW
Both blends share the same three-peptide foundation (BPC-157, TB-500, GHK-Cu). KLOW adds KPV as the fourth component. If inflammation is not a primary variable in your research model, GLOW provides a more focused three-pathway approach. If your protocol requires an anti-inflammatory signaling component alongside tissue repair and matrix remodeling research, KLOW is the appropriate formulation.
Sourcing and verification
KLOW is a more specialized product than GLOW and is stocked by fewer vendors. Paramount Peptides and Swiss Chems are the primary vendors currently offering KLOW with verified third-party COAs. Always request component-level verification — a single purity figure for the blended product is insufficient documentation for a four-component formulation.
