Frequently asked

How is purity verified?

Every batch is independently tested by third-party labs using HPLC and mass spectrometry. We publish ≥99% purity results so you can verify what you receive.

Do you provide a COA?

Yes. A lot-specific Certificate of Analysis accompanies every batch, with the assay method and results traceable to the exact lot you order.

How should compounds be stored?

Store lyophilized material at 2–8°C, protected from light. Once reconstituted, keep refrigerated and use within the timeframe noted on the product page.
