PuraCore summary of this report (PDF)
Overview

KLOW Blend.

Four of our peptides, freeze-dried together: GHK-Cu, the copper tripeptide; KPV, the three-residue end of alpha-MSH; BPC-157, fifteen residues long; and TB-500, built on thymosin beta-4. They sit side by side in the cake with no bonds between them.

Total fill is 80 mg. Being a mixture, it has no single CAS number or formula; the laboratory report lists each of the four components and gives it its own result.

PuraCore offers no advice on how any material is used, prepared or applied. Deciding whether it fits your research rests with you or your institution.
