What a COA (Certificate of Analysis) Should Include Identity Confirmation Mass spectrometry confirming the correct molecular weight: Mod GRF 1-29 (no-DAC): 3,368.7 Da CJC-1295 DAC: ~3,647 Da (includes MPA linker) Amino acid sequence verification with the four modifications at positions 2, 8, 15, and 27 For DAC form: confirmation of the MPA conjugation Purity Testing HPLC purity look for 98%+ purity The chromatogram should show a single dominant peak Contamination Testing Endotoxin levels (bacterial contamination) Residual solvent analysis (acetonitrile, TFA) Heavy metals screening How to Verify a COA Is Legitimate Check the testing lab Reputable labs include Janoshik Analytical, MZ Biolabs, and Colmaric Analyticals
