three years of excursion threads, summarised so you do not have to read them
The title is the argument: three years of excursion threads, summarised so you do not have to read them. Here is the rest of it.
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.
Regional stock changes the question rather than answering it: shorter lanes mean less exposure and fewer variables, which is why the warehouse question is worth asking before ordering in summer.

Once in solution, the relevant risks are hydrolysis, aggregation and, for some sequences, oxidation. Refrigeration slows all three; freezing a solution introduces a separate risk at the ice interface.
Gel packs are designed for a duty cycle. A liquid pack at the end of a longer-than-expected transit is a pack behaving as specified, not evidence of an excursion in the vial.
