Wrote the reconstitution date on the vial for the first time last year. Have never once since wondered how old a solution is. Split an order across two months deliberately to compare summer…
You cannot infer potency from a temperature record. The record tells you what happened to the box; only a test tells you what happened to the material.
Put a logger in three consecutive orders. Two never went above the range at all and the third spent four hours warm on a Friday. Cost me almost nothing to stop wondering.
Gel pack fully liquid on arrival, powder tested 98.2% against a claimed 97.5% afterwards. The pack had done its job for as long as it was designed to.

That is the ambient temperature at the destination, not the temperature inside the box. The logger measures the second one.
Do you know what storage condition the stability statement covers?
the excursion that matters is the one after reconstitution
