Purity claims are easy to print and impossible to trust. So we built NOUR around evidence: independent testing, batch-level certificates, and a QR on every vial that opens its own results.
Every batch is identity-confirmed by ESI mass spectrometry and purity-graded by reverse-phase HPLC at independent labs — Janoshik Analytical and Freedom Diagnostics — so the numbers aren't marking our own homework.
No generic certificates. The lot on your vial maps to one specific Certificate of Analysis — identity, purity, single impurity, net peptide, endotoxin and bioburden.
The QR on every carton and label opens nour-labs.com/use — authenticate the lot, read the COA, and run the reconstitution calculator. Counterfeits can't fake a live lookup.
Lyophilized, sealed under inert conditions, and shipped 2–8°C with protection from light — so what arrives matches what was tested.
A NOUR lot isn't released until each parameter passes its specification. Here's the panel that sits behind every product.
