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

Calibration Standards for the amount of Niclosamide in solution versus pH S3.1 Experimental Calibration standards (of 20uM, 50uM, 100uM, 150uM, 200uM, 250uM and 300uM) for the UV/Vis experiment were prepared by injecting 100uL of each ethanolic niclosamide solution into 10 mLs of the 9.3 pH buffer giving a 1:99 dilution and a final 1% ethanol solution of niclosamide
