LAB REPORTS, COA LIBRARY
Every new lot runs a 7-point QC panel at an independent third-party lab, never in house: identity by LC-MS, purity by HPLC, quantity, sterility, endotoxins, heavy metals by ICP-MS, and a fentanyl screen. The work is split across five labs: ILS Laboratories, MDx BioAnalytical, Freedom Diagnostics, Chromate and Bioviridian. The vendor is separately graded by Finnrick, the research community's grading body. The lot number printed on your vial ties back to that batch's own certificate, and every card below names the lab that signed it. Search your lot, read the numbers, keep the PDF.
A certificate of analysis (COA) records the results reported for a tested sample. Start with the compound and lot, then read the methods and results on that specific report. Read the COA guide for the difference between purity, identity and measured quantity.

Score is the sum of three components: purity (0 to 4), quantity accuracy (0 to 4), and batch identification (0 to 2). Test it yourself. If a vial doesn't match our published COA, full refund and you keep the vial.
QUESTIONS
Match the lot number printed on your vial to the certificate of analysis published on this page. Each COA names the independent lab, the batch, the HPLC purity percentage, and the mass-spec identity confirmation for that exact lot, so a real report always maps to your specific vial.
Yes, and it is designed to be self-verifiable. Every batch runs a 7-point QC panel at an independent third-party US lab, not tested in-house, and the lot number on each vial ties to that batch's own published COA. If your own independent test contradicts the published COA, you get a full refund and keep the vial.
Independent third-party laboratories (ILS Laboratories, MDx BioAnalytical, Freedom Diagnostics, Chromate and Bioviridian) run the HPLC and LC-MS analysis, and Finnrick, the research community's independent grading body, assigns the grade. Next Level Labs does not grade its own numbers.
Finnrick grades peptide suppliers by buying samples blind and testing them by HPLC, then scoring the vendor. Next Level Labs does not yet have its own vendor page on Finnrick. What Next Level Labs publishes instead is specific to your purchase: every lot is tested by an independent laboratory and the signed certificate of analysis is published on the lab reports page before you order, matched to the lot number printed on the vial.
All NLL products are sold for in vitro research use only. The presence of a COA does not constitute an endorsement of human use. Not evaluated by the FDA.
