Manufacturer-Issued, Third-Party Tested

Certificate of Analysis library

Coast Star Labs sources this catalog from a single manufacturer. Certificates below are issued directly by that manufacturer's independent U.S. testing lab and are linked here unedited — we don't rehost, rebrand, or alter them.

How to read this table Products with an accession number below have a certificate we've directly confirmed. For products not yet listed with a specific accession number, current documentation is available from the manufacturer's public COA library — link at the bottom of this page.
