Researchers select GHK-Cu for its relevance in studying cellular communication, copper-binding mechanisms, and molecular signaling pathways in controlled experimental models
What a COA should show: For a raw GHK-Cu ingredient, a legitimate Certificate of Analysis should include HPLC purity (look for greater than 98 percent), mass spectrometry confirmation of the molecular weight (340.38 Da for the free tripeptide), copper content by ICP-MS, and heavy metal panel
