proven track record
Most results back in 1-3 business days. While competitors take 5 to 11 days, your COA is ready before your next shipment goes out. Speed without compromise.
Every COA is searchable by accession number or company name. Your clients can verify any batch independently — no black boxes, no unverifiable claims, ever.
HPLC confirms purity. LC-MS confirms identity. We never issue one without the other — because a purity number without identity confirmation is an incomplete answer.
No vendor affiliations. No supplier relationships. No conflicts of interest. We test for the research community — and that independence is what makes our results mean something.
From coast to coast, vendors across the U.S. ship samples to Freedom Diagnostics and get results back faster than any other lab in the country. Wherever you are, we have got you covered.
Named by vendors, cited in group buys, and reviewed publicly by the researchers who rely on us. Our reputation was built sample by sample since day one in 2023.
