Every batch arrives with its own paperwork

We do not sell from a photo and a purity claim. Each production lot is sampled, tested by an independent laboratory, and released only when the numbers match the specification.

  • Reverse-phase HPLC — quantitative purity at 220 nm, full chromatogram included.
  • ESI mass spectrometry — molecular weight confirmed against theoretical value.
  • Lot traceability — every vial carries a lot number that maps to its certificate.
  • Handling data — reconstitution, storage and stability guidance on the datasheet.

Independent lab, not in-house

Testing is performed by an accredited third-party facility. We publish their report, not our own.
