About this verifier

  • ·Independent testing. All Certificates of Analysis are issued by third-party laboratories — never self-certified. Reports include HPLC purity and mass spec identity confirmation.
  • ·Batch-specific. Every batch is tested and has its own CoA — we do not re-use a single certificate across shipments.
  • ·Don’t have your code?The batch code is printed on the sticker on the side of the pen and also appears in the order email. If you can’t find it, message us on WhatsApp and we’ll send the CoA for your order directly.
