Verify a report yourself
Each certificate of analysis lists the lab and lot. You can confirm results on the testing lab's own website, such as FreedomDiagnosticsTesting.com or horizonanalytical.com. Our About page shows live testing statistics, including any lots on sale that tested below 98%.
COAs for your customers
Resellers and private label buyers can pass lot reports on to their own customers. On private label vials, lot, expiry and purity are printed straight from the lot's report.
