Every production batch is submitted to an independent ISO-17025 aligned testing facility for HPLC purity analysis and mass spectrometry confirmation. The full archive is public. Certificates can be downloaded without account.
No batch leaves the facility without a complete third-party assay. The lab partner is independent of our supply chain — they have no stake in the outcome, they simply report what they measure. When a batch fails the ≥99% threshold, it is not released.
The testing protocol covers HPLC purity determination, mass spectrometry confirmation of target identity, water content analysis by Karl Fischer titration, acetate content, and bacterial endotoxin screening. Results are published as downloadable PDFs, linked from every product and batch record in this archive.
