How to read a COA

IDENTITY

Mass spectrometry

Confirms the molecular weight matches the expected sequence — the compound is what the label says it is.

PURITY

HPLC chromatogram

Shows the percentage of the sample that is the target peptide versus impurities or related sequences.

CONTENT

Net peptide content

States how much of the vial's mass is peptide versus counter-ions and residual water — essential for accurate research calculations.
