Every RetaNord batch is verified by testing through Veritalys (earlier batches: Janoshik) using HPLC for purity and content. 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 for testing through Veritalys, an EU peptide testing service. Nothing ships until it clears every check below.
A vial is drawn at random from each production lot and sent for testing at an independent EU laboratory, arranged through Veritalys — 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%+.
HPLC against a reference standard confirms the sample is the target compound — proof the vial holds what the label says.
Endotoxin measured on each lot (LAL), plus aerobic count, yeast and mould, E. coli and Salmonella on every full-panel lot.
The signed report is published here and travels in the box. The batch number on your vial matches the certificate above.
