GHK-Cu is the copper complex of glycyl-L-histidyl-L-lysine. Because databases represent copper coordination and charge states differently, formula and mass should always be matched to the exact complex named on the lot certificate.

Published work includes cell, tissue and animal models examining copper transport, extracellular-matrix signalling, gene expression and wound-repair biology. These experimental observations are not evidence that an unapproved research vial is suitable for cosmetic or human use.

Registry values can differ by salt, counter-ion, hydrate, charge state or supplier representation. The lot certificate takes precedence.

1. 01

   Keep the sealed lyophilised material dry, protected from light and tightly closed.

2. 02

   For longer-term laboratory storage, -20°C is a commonly used condition for peptide reference materials; short-term requirements vary by sequence and formulation.

3. 03

   After preparing a laboratory solution, minimise time at room temperature and repeated freeze-thaw cycles. The lot-specific label, CoA and SDS take priority over general guidance.
