What a COA (Certificate of Analysis) Should Include Identity Confirmation Mass spectrometry confirming correct molecular weight (~401 Da for GHK-Cu, ~340 Da for GHK alone) Explicit identification of the product as GHK-Cu (copper complex), not GHK alone Amino acid sequence verification matching Gly-His-Lys Purity Testing HPLC purity look for 98%+ purity HPLC chromatogram should show a single dominant peak Copper content analysis (atomic absorption or ICP-MS) confirming stoichiometric chelation Contamination Testing Endotoxin levels (bacterial contamination) Residual solvent analysis (acetonitrile, TFA) Heavy metals screening (other than the intentional copper) How to Verify a COA Is Legitimate Check the testing lab Reputable labs include Janoshik Analytical, MZ Biolabs, and Colmaric Analyticals
