VIP acts at VPAC1 and VPAC2 in vasoactive and immunomodulatory signalling; KPV is the α-MSH tail studied for NF-κB and epithelial inflammation. Klow already carries KPV next to its repair peptides — this pairs it instead with VIP, which no blend in the catalogue covers.\u003c\/p\u003e\n\u003cp\u003eEach pen arrives sealed, pre-filled and individually batch-tested.\u003c\/p\u003e\n\u003cp\u003eFor laboratory research use only.
