What a Meaningful Glutathione Certificate Should Include Complete gamma-L-glutamyl-L-cysteinylglycine identity Confirmation that the material is reduced glutathione Observed intact molecular mass Structural evidence supporting the gamma linkage Quantitative reduced-glutathione assay Glutathione disulphide result Related-peptide and free-amino-acid profile Named and unknown impurity results Water-content result Residual-solvent results where relevant Elemental-impurity results where appropriate pH and appearance for finished solutions Particulate testing for injectable products Bacterial-endotoxin testing for injectable products Sterility testing for injectable products Finished-product batch number Testing-laboratory identity Methods and acceptance criteria A clear statement of tests not performed Why 99% Purity Is Not Enough A chromatographic percentage does not prove how much of the material remains in the reduced GSH form

The research rationale rests on three arguments, each with a corresponding caveat
