What Is a Certificate of Analysis (COA) and How Can I Verify Mine?

A Certificate of Analysis (COA) confirms that each batch of peptides meets our quality, purity, and identity standards. Every product we offer is independently tested before it becomes available for research.

We partner exclusively with Freedom Diagnostics, a U.S.-based testing laboratory specializing in peptide analysis. Each COA details key metrics such as purity (HPLC/UPLC), molecular weight (Mass Spec), appearance, and batch identification.

How to Find and Verify a COA

Most COAs can be found directly on the product page of our website.
The COA is typically the second image displayed in the product listing.

If you’re unable to locate your specific batch number, please email us and include a photo of the lot number printed on the side of your vial — our support team will be happy to provide your corresponding COA.

Third-Party Verification

All COAs can also be confirmed directly through our testing partner:

• Website: https://freedomdiagnosticstesting.com

• Email: freedomdiagnostics.net

Simply include your product name and batch or lot number when requesting confirmation.
