## KLOW peptide references: the full citation record

Every quantitative claim on this site maps to a numbered reference below. Citations are drawn from the peer-reviewed literature on the four components of the KLOW blend — KPV, GHK-Cu, BPC-157, and TB-500/thymosin beta-4. No citation here was constructed or extrapolated; each is a published study, review, or regulatory document. Blend-level claims are explicitly attributed to component-literature extrapolation, not blend studies, because no controlled blend study has been published.
