Every vial we ship carries a printed lot number tied to one production batch. Verification takes under a minute — no account, no form.
It is printed on the vial label, e.g. LOT TZ2643.
One message with the lot code is enough.
You get the third-party analytical report for that exact batch as a PDF.
Reports are issued per batch and tied to the lot code on your vial — we do not send generic certificates.
