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.
How we verify every batch
HPLC Purity Analysis
High-Performance Liquid Chromatography isolates and measures each compound's components to confirm 99%+ purity before release.
Mass Spectrometry
Molecular weight analysis confirms each compound's identity and structural integrity down to the exact expected mass.
Identity Verification
Amino acid sequencing confirms the compound in each vial matches its labeled research reference, with no substitutions.
Batch Documentation
Every batch is released with a full quality record covering identity, purity, and appearance checks completed prior to shipping.

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.
