Every lot is assayed by HPLC and confirmed by mass spectrometry before it is released. We publish the exact figure rather than a rounded claim, and nothing below 99% is listed for sale.

Every product page links directly to its Certificate of Analysis, and the full COA Library lets you search by compound name or lot number. Your vial's label carries the lot number needed to pull up the exact report for the batch you received.

Compound identity, lot number, net content, the analytical method used, the measured purity and the pass or fail result, along with the date the report was issued and the laboratory that ran it.

Before reconstitution, keep lyophilised vials in the freezer for long-term storage, or in the refrigerator if they will be used within a short period. Once reconstituted, store them in the refrigerator. In both cases protect them from light and avoid repeated temperature swings.

Orders placed on a business day are picked and verified against their lot records the same day where possible. Everything ships sealed and protected, with tracking provided on every shipment.
