  • Identity

    LC-MS

    Mass spectrometry confirms the molecular mass matches the compound named on the label.

  • Net peptide content

    HPLC quantitation

    Measures how much peptide is actually in the vial against the label claim.

  • Appearance

    Visual inspection

    The lyophilised cake is checked for colour, uniformity and integrity before release.

  • Endotoxin

    LAL · kinetic

    Bacterial endotoxin is quantified and reported on each certificate.

  • Heavy metals

    ICP-MS

    Screens for lead, arsenic, cadmium and mercury against strict limits.
