Every batch, independently tested — and we show the paperwork
Each production batch is tested by an independent third-party lab using HPLC and mass spectrometry to verify identity and purity. The Certificate of Analysis reports the batch number, purity percentage, and method so you can confirm quality yourself — not take our word for it.
- Third-party HPLC + mass-spec verification
- A COA issued for every batch, with a traceable lot number
- Batch-to-document traceability you can cross-check
