About this material

Molecule class and status

KLOW is a four-component peptide blend supplied in one vial: BPC-157, TB-500, GHK-Cu (a copper complex of the tripeptide glycyl-L-histidyl-L-lysine) and KPV (the tripeptide lysyl-prolyl-valine). Amounts per component are listed in the specification table, taken from the product page and lot certificate. Each component is identified and assayed on the certificate. The blend is intended only for laboratory research.
