Every SS-31 lot is tested by an independent ISO/IEC 17025 laboratory and the signed certificate of analysis is published before you order. Match the lot number printed on your vial to the report on the lab reports page. If the lot on the glass is not published there, do not use it.

Is SS-31 third-party tested? +

Yes. Every SS-31 lot runs a 7-point QC panel at an independent third-party US lab: identity, purity by HPLC, quantity, sterility, endotoxins by LAL, heavy metals by ICP-MS and a fentanyl screen, at 99.80% purity. The signed certificate for the exact lot you receive is published before you order. The signed certificate of analysis for the exact lot you receive is published on the lab reports page and available before you order.

How do I verify my SS-31 is legit? +

Match the lot number printed on your vial to the certificate of analysis published on the Next Level Labs lab reports page. It names the lab, batch, purity, and identity confirmation for that exact lot, so a real report always maps to your specific vial.
