Every RetaNord batch is verified by an independent third-party laboratory (Janoshik) using HPLC for purity and mass spectrometry for identity. The lot number on your vial matches its certificate — tap any report to open it in full.
Before a lot earns the RetaNord label, a vial is pulled at random and sent to Janoshik — an independent analytical laboratory with no stake in the result. Nothing ships until it clears every check below.
A vial is drawn at random from each production lot and sent to a third-party lab — not tested in-house, so the result is impartial.
High-performance liquid chromatography quantifies purity and separates out synthesis by-products and degradation. Target: 99%+.
Mass spectrometry confirms the molecule matches the target structure by exact mass — proof the vial holds what the label says.
Independent screening for bacterial, fungal and endotoxin contamination, so a failed batch never reaches a bench.
The signed report is published here and travels in the box. The batch number on your vial matches the certificate above.
