KLOW Blend (GHK-Cu, BPC-157, TB-500, KPV)

What is the KLOW blend?

“KLOW” is the name the research-peptide market uses for a four-peptide blend in a single vial. It is the GLOW blend (GHK-Cu, BPC-157 and TB-500) with a fourth peptide, KPV, added. KLOW is commonly sold as an 80mg vial.

GHK-Cu: the copper(II) complex of the tripeptide Gly-His-Lys (copper tripeptide-1).
BPC-157: a synthetic 15-amino-acid peptide (GEPPPGKPADDAGLV).
TB-500: a synthetic peptide related to thymosin beta-4.
KPV: the tripeptide Lys-Pro-Val, derived from the C-terminal end of alpha-melanocyte-stimulating hormone (alpha-MSH).
