How every batch is tested
Every Loti Labs batch is tested by an independent, U.S.-based third-party laboratory. Purity is measured by HPLC and identity is confirmed by mass spectrometry. Where a certificate includes an endotoxin screen, the result is shown above. Each certificate is archived permanently under its batch number, so earlier batches stay on record after a new one arrives. Search the complete COA archive.
