Read the evidence
Distinguish free GHK, a defined copper complex and a finished topical formulation. Delivery-system research is not proof of clinical rejuvenation.
Resolve the identity
Copper stoichiometry, protonation and counterion affect the formula. A peptide-only purity measurement does not fully characterize a metal complex.
