A pre-blended formulation combining four peptides in a single 80MG vial: BPC-157 (10mg), TB-500 (10mg), GHK-Cu (50mg), and KPV (10mg). The blend extends the GLOW formulation with KPV, an α-MSH C-terminal tripeptide referenced in research on inflammatory and immune-pathway signaling. KLOW is referenced in research applications studying tissue-pathway, matrix-protein, angiogenic-pathway, and inflammatory-pathway models in parallel.
Each lot is independently HPLC-verified for all four component peptides separately, with a combined Certificate of Analysis documenting each component. The blue tint from GHK-Cu's copper coordination is visible in the reconstituted solution.
This material is supplied for in vitro research only. It is not a drug, supplement, food, or cosmetic, and is not for human or veterinary consumption.
