Verified two ways, then independently
Each production batch is sent to Freedom Diagnostics, an independent analytical laboratory. They run two orthogonal methods, one for purity and one for identity, and issue a signed certificate for every lot.
HPLC purity
High-performance liquid chromatography separates the sample and measures how much of it is the intended compound, reported as a purity percentage on every certificate.
LC-MS identity
Liquid chromatography–mass spectrometry confirms the compound's identity by molecular mass, verifying the vial contains exactly what the label states.
Independent verification
Freedom Diagnostics hosts each certificate publicly, so any batch can be confirmed at the source rather than taken on faith. Every COA below links to that original document.
Published batch certificates
Every certificate we have published is listed below, each tied to its lot and accession number, with a link to the original document on Freedom Diagnostics.
