What Does 99.8% Peptide Purity Actually Mean? A Technical Breakdown
What 99.8% Purity Actually Means When a peptide tests at 99.8% purity, that number comes from a specific analytical measurement: High-Performance Liquid Chromatography, or HPLC. It’s not a marketing estimate or a rounded figure. It’s the output of a laboratory instrument that separates and quantifies every molecular component in a sample. Understanding what that number […]
