Verify a PurityBioLabs product.

Every lot of every product we ship is independently third-party tested. A Certificate of Analysis (COA) documents the material’s identity and purity so you can trust exactly what is in the vial.

What a Certificate of Analysis shows

• Product identity and lot number
• Purity (e.g. by HPLC) and identity confirmation (e.g. by mass spectrometry)
• Test method(s) and date of analysis

Find your lot

Scan the QR code on the vial label or the packing slip, or pick your SKU below. That page confirms the product, its SKU, the current lot and the expiry date, and links the Certificate of Analysis for that lot once it has been published.
