Every batch of Pure Peptides compounds is independently tested by accredited third-party laboratories before release. We use HPLC (High-Performance Liquid Chromatography) to verify compound identity and purity.
Test results are published here as soon as they are received. Each lot number is unique to a specific production batch, allowing you to trace your exact vial to its test certificate.
