Lab Verified
Backed by Real Lab Results
Every batch is independently tested by a third-party lab and shipped with a full report confirming purity and identity.
Documentation you can verify
A Certificate of Analysis (COA) is the record that confirms what's in every vial matches what's on the label. We publish one for every batch we release — no exceptions, no request required.

Certificate of Analysis — Common Questions
A COA is a lab-issued document confirming what a specific batch actually contains — including identity, purity percentage, and molecular weight — verified through independent testing rather than taken on faith.
Every product page includes a link to view or download the current batch's Certificate of Analysis. You can also request a specific batch's COA by emailing support@prestigesciences.com with your order number.
Each COA lists the tested purity percentage, confirmed molecular weight, the testing method used, and the date testing was completed. A passing result matches or exceeds the purity standard listed on the product page.
Yes. Testing is performed by independent third-party U.S. laboratories holding ISO 17025 accreditation, the standard for testing and calibration lab competence.
Every batch is tested individually before it's released for sale — not just periodically or by sampling across a production run.
