What to know about the research

Distinguish free GHK, a defined copper complex and a finished topical formulation. Delivery-system research is not proof of clinical rejuvenation.

Check the exact compound

Copper stoichiometry, protonation and counterion affect the formula. A peptide-only purity measurement does not fully characterize a metal complex.
