Keeping records of expected potency and comparing batch performance over time helps identify gradual degradation before it becomes complete loss
Research-grade peptides should have batch-specific Certificates of Analysis showing third-party HPLC purity testing and mass spectrometry molecular identity confirmation, plus peptide content verification confirming the actual peptide mass per vial
it fundamentally changes the peptide's behavior and, consequently, your research design
