In manufacture, if copper is sub-stoichiometric or loading is incomplete. In storage or solution, if a competing ligand — a chelator in a buffer, albumin in serum, another peptide — takes the copper. The second route means a lot that was fully loaded at release can develop the impurity later under the wrong conditions.
It is therefore both a manufacturing specification and a stability indicator.
Mass spectrometry shows a peak about 61 mass units below the complex, lacking the two-peak copper signature. Dual-wavelength HPLC shows a peak in the ultraviolet with no counterpart in the visible. Elemental copper content below the 1:1 value is the bulk measure.
Any one of these indicates it; together they quantify it.
Because GHK-Cu is defined as the complex. The literature studied the complex; the catalogue sells the complex; the properties described anywhere on this site are properties of the complex. The free peptide is a different material and its presence is a deviation from specification.
GHK-Cu is supplied by REVIVE LAB UAE for laboratory research use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not for human or veterinary use, and no dosing, administration or protocol guidance is provided.
