Certificates of Analysis & Third-Party Testing
Every batch is sent to an independent third-party laboratory [name the lab] and analyzed by high-performance liquid chromatography (HPLC) for purity and by mass spectrometry for identity. We publish the resulting Certificate of Analysis so you can verify what you're buying before you order.
- Compound identity confirmation (mass spectrometry)
- Purity percentage (HPLC)
- Batch / lot reference and test date
- Issuing laboratory
Each product page links to its current Certificate of Analysis. If you can't find a COA, contact us before ordering — and remember that a verified COA is one of the clearest signs you're on the official Peptide Sciences site rather than a counterfeit.
