Certificates of Analysis (COA)
Every peptide batch we ship is independently verified by a third-party analytical laboratory. A Certificate of Analysis (COA) is available on request for every lot sold.
What’s on a Vera Peptides COA
- Identity confirmation by mass spectrometry (MS)
- Purity assay by reverse-phase HPLC (typically ≥98%)
- Lot number traceable back to the source synthesis batch
- Date of analysis and analyst signature
- Independent lab signature (third-party verification)
How to Request a COA
