Retabionix summary of this report (PDF)
Composition

KLOW Blend.

KLOW combines four peptides in a single vial: GHK-Cu, KPV, BPC-157 and TB-500. The amount of each is printed on the label.

Because it is a blend, it does not have a single CAS number or formula. The certificate lists each peptide and its amount separately.

We do not give guidance on preparing, using or applying any material. Whether a compound suits your research is for you or your institution to decide.
