GHK-Cu is a copper-binding tripeptide popular for skin and hair research. Quality varies enormously and the copper complex itself is often missing or incorrect.
Copper-binding tripeptide
Also known as: Copper Peptide
Why test GHK-Cu?
GHK-Cu without bound copper is just GHK. LC-MS identity confirms the copper complex; HPLC confirms purity of the peptide fraction.
Common issues we find
GHK only - no copper complex
Low purity (<92%)
Under-fill
Frequently asked questions
Can LabDoc confirm the copper complex is present?
Yes - LC-MS identity confirms the GHK-Cu mass with the bound copper ion, distinguishing it from plain GHK.
