Lab Tests & Certificates of Analysis

Don't Take Our Word for It. Look up the Batch.

Every published batch is tested by an independent, A2LA-accredited lab.

Pick a batch below to pull its certificate — the same data printed on your vial.

How to read a certificate

  • ✓Every published lot is HPLC-tested for purity and assay, plus an LAL endotoxin screen.
  • ✓Pass means the lot cleared the accredited lab's spec for that assay.
  • ✓The lot number on your vial matches the certificate shown here.

How every lot is tested

Three Assays, One Independent Lab

  1. 01

    Purity — HPLC-UV/VIS

    Chromatographic purity quantified to the tenth of a percent and published — not a “99%+” badge.

  2. 02

    Assay — HPLC-UV/VIS

    Confirms the vial's labeled content by the same chromatographic method, so the milligrams are real.

  3. 03

    Endotoxin — LAL

    The A2LA-accredited lab runs the LAL screen and prints its own pass/fail call — we publish that verdict exactly as it reads. Its certificates state that criterion as the USP/FDA threshold of 5 EU/kg — 350 EU total for a 70 kg adult.
