How to read these numbers

The purity is the number the lab measured, not a floor. 99.31% means 99.31%, never “at least 99”. It comes from reversed-phase HPLC; identity is confirmed separately by mass spectrometry.

We don’t test our own product. Every lot goes to an independent, named lab — this one to Accurate Lab Tests. The certificate is published here before the buy button works, and the lot number on your vial is the one on the report.

If a batch misses its spec, it never ships. And if a vial you hold doesn’t match its report, test it at any lab you like and we refund every dollar. Holding a vial now? Look up its lot number in the registry.

For research use only. Not for human or veterinary use. Not intended to diagnose, treat, cure, or prevent any disease. Sold and handled strictly as a laboratory research chemical; by purchasing you confirm you are a qualified researcher.
