About KLOW

KLOW is a multi-peptide blend combining GHK-Cu, BPC-157, TB-500 fragment, and KPV in a single 80 mg lyophilized formulation. The blend is supplied for comprehensive regenerative-research applications where multi-component intervention is part of the study design.

Component peptides are individually tested for identity and purity before blending; the final product is independently verified for aggregate purity and endotoxin content per batch.

Each component peptide is documented in its own monograph in the COA Library for reference.
