Lot-level traceability
Every vial carries the lot number it was filled from. Enter it on the verification page and you get that lot's own record — when we received it, when it expires, and whatever testing is recorded against it.
02
Documented purity
Where a lot has been assayed, the verification page shows the measured figure, the laboratory that reported it and the date.
03
Cold storage, dated stock
Lyophilized material held at −20 °C, with a dated expiry on every lot — three years from the date we received it.
