A theoretical mass calculated from the three-residue sequence describes GHK, not GHK-Cu. The complex carries the copper, and the measured mass reflects that.
This catalogue states it as approximately 340 daltons for the peptide plus the coordinated Cu(II), deliberately keeping the two parts visible. Reading a figure for GHK alone against a certificate for the complex is the commonest way to think a lot has failed specification when it has not.
The complex behaves differently from the free peptide on a reverse-phase column, and a method developed for one is not automatically right for the other. Mobile-phase conditions can also affect whether the complex stays intact through the run.
A certificate that states its method is therefore giving more than one that states only a number — the number means something different depending on how it was obtained.
Peptides are usually detected in the far ultraviolet, where the peptide bond absorbs. The copper centre additionally absorbs in the visible range, which is why the material is blue and why it is handled as light-sensitive.
That visible absorbance is also a crude confirmation that the metal is coordinated rather than free, available to anyone who opens the vial and looks.
