FAQs

We partner exclusively with ISO 9001:2015 certified facilities. Every batch is independently third-party tested by a U.S.-based laboratory before it is approved for release. Each batch is verified for identity (LC-MS), purity (HPLC-UV), net content, and endotoxin (LAL assay, USP <85>). Vials are clearly labeled with the compound and its batch (lot) number, and that number matches the batch-specific Certificate of Analysis published for it. Matching the two confirms the vial you received came from the batch that was tested. Visit our COA library and COA archive to view our public test results.

Yes. Every batch is independently tested by Freedom Diagnostics, a third-party U.S. laboratory, before it is approved for release. Testing covers identity by liquid chromatography and mass spectrometry (LC-MS), purity by high-performance liquid chromatography with UV detection (HPLC-UV), endotoxin by LAL assay (USP <85>), and net content. Certificates of Analysis (COAs) are published for every compound. Search by compound in our COA library, or view the COA archive to find all public test results.

Sealed lyophilized (freeze-dried) vials remain stable for up to 24 months when stored at -20°C. For short-term storage or upon receipt, refrigerate sealed vials at 2°C to 8°C, protected from light and moisture. Always handle and store materials under standard laboratory protocols.

Every order ships in a secure, reusable magnetic case, inside insulated protective packaging. The packaging is designed to maintain compound stability and prevent physical or UV damage during transit, ensuring your research materials arrive safely and securely.
