Verify a LYOPEP batch

Every vial we ship carries a printed lot number tied to one production batch. Verification takes under a minute — no account, no form.

  • 1
    Find the lot number

    It is printed on the vial label, e.g. LOT TZ2643.

  • 2
    Send it to us on WhatsApp

    One message with the lot code is enough.

  • 3
    Receive the batch report

    You get the third-party analytical report for that exact batch as a PDF.

Verify a lot on WhatsApp

Reports are issued per batch and tied to the lot code on your vial — we do not send generic certificates.
