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.
How to view a COA
There are two ways to reach the COA for the exact lot you received:
- Scan the QR code on the vial label or the packing slip — it opens that SKU’s authenticity page.
- Visit PurityBioLabs Verify and select your product, or go directly to
/verify/<your-SKU>.
What a COA 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
Requesting a specific lot’s COA
If you need the COA for a specific lot and cannot locate it, email us at support@puritybiolabs.com with your order number and the product SKU and lot number, and we will send it to you.
