A single purity figure underdetermines a co-formulated peptide vial. What area percent measures, why it is not the component ratio.
Research grade vs pharmaceutical grade: no law defines the first. What grade labels mean for peptides, and how to check a purity claim before you order.
Why a 10 mg peptide vial isn't 10 mg of peptide: net peptide content, TFA vs acetate counter-ions, how they're measured and when they matter in the lab.
