A COA is an official document issued after independent third-party laboratory testing. It confirms the identity, purity, and concentration of a compound in a specific batch. Every batch we ship has a corresponding COA published here.
Scan the QR code on this page or on the physical vial label — both link directly to this COA page. The batch number, purity, and dates are tied to the lab report and cannot be altered after publication.
We use High-Performance Liquid Chromatography (HPLC) for purity analysis, along with Mass Spectrometry (MS) for identity confirmation. All testing is conducted by independent, accredited third-party laboratories.

Purity refers to the percentage of the stated compound relative to total detected substances in the sample. A purity of ≥ 98% means at least 98% of the measured content is the target compound — the remainder may be trace solvents or residuals within acceptable limits.
No. All products are strictly for laboratory and research use only. They are not approved for human or veterinary consumption, and are not dietary supplements or therapeutic agents.
An expired or superseded batch should not be used in research. Contact our support team to arrange a replacement or to source the current active batch. Expired COAs are kept on record for archival and traceability purposes only.
