GHK-Cu (Copper Peptide)

Research overview

GHK-Cu refers to the copper complex of the tripeptide glycyl-L-histidyl-L-lysine. Copper coordination is part of its identity, so the uncomplexed peptide GHK and a different copper peptide should not be treated as equivalent materials. Researchers investigating extracellular-matrix biology can use this page to connect the available catalogue specifications with a clearly identified starting reference.

What the referenced research shows

In vitro study — collagen synthesis in fibroblast cultures

Maquart and colleagues examined collagen synthesis in fibroblast cultures in a 1988 laboratory study of GHK-Cu. The investigators reported a response in that experimental system. This is cell-culture evidence, not proof that a research product provides a cosmetic result or treats a condition in people. Interpretation depends on the material, model and measurements used in the experiment; the paper does not certify a commercial batch.

Identity and comparison notes

Distinguish GHK-Cu from GHK, AHK-Cu and blended products. Similar names and colour are not sufficient identity checks. The chemical form described in the documentation should match the material required for the experiment; do not infer the copper content or peptide content from a photograph.

Questions to ask about this batch

When reviewing GHK-Cu documents, ask how identity and copper-related composition were characterized, and what the stated purity result actually measures. Match the SKU and lot before comparing results. A chromatographic area percentage and the mass of peptide present are different measurements and should not be substituted for each other.
