Certificate of analysis

Purity is a number, not an adjective

Every lot is sent to an independent laboratory before it is released. The report comes back with a figure, a method (HPLC and mass spectrometry) and a lot number. If a lot does not clear our threshold it does not ship.

The certificate for the material in your hand is available on request. Quote the lot number and serial printed on the label, and we send the report.
