Quality standards

Eight tests on every batch.

Run by accredited third-party laboratories and published with the product — the laboratory document itself, not a summary of what it found.

  1. 01

    Peptide purity

    Reverse-phase HPLC

    Separates and quantifies the target compound against related substances.

  2. 02

    Net peptide content

    Nitrogen analysis

    Confirms how much of the vial's mass is peptide rather than salts or moisture.

  3. 03

    Identity

    Mass spectrometry

    Verifies the sequence against a certified reference standard.

  4. 04

    Appearance

    Visual inspection

    Checks the lyophilized cake for colour, form, and any visible defect.

  5. 05

    Fentanyl screen

    Immunoassay

    Screens for fentanyl and analogues as a contamination control.

  6. 06

    Heavy metals

    ICP-MS

    Measures lead, arsenic, cadmium, and mercury at trace levels.

  7. 07

    Sterility

    PCR

    Detects bacterial contamination in the finished vial.

  8. 08

    Endotoxin

    LAL assay

    Returns a quantitative endotoxin result, not a pass/fail.

Every certificate is published.

Results are not paraphrased. The signed document for the batch you receive is on the certificates page, and the batch code is on the vial.
