[Meta] the lyophilised rule is doing its job and people should stop complaining
the lyophilised rule is doing its job and people should stop complaining. Nothing about this affects the ranking maths, before anyone asks. Moved everything off the fridge door after reading a thread here and my temperature log immediately got boring. Gel pack fully liquid on arrival, powder tested 97.6% against a…
Lyophilisation removes the water that drives most degradation pathways. That is why the dry cake is comparatively robust and the reconstituted solution is not.
A transit temperature logger records a distribution, and time above a threshold matters as much as peak temperature. That is the argument for logging rather than guessing.
if you want to know, log it, otherwise you are guessing

Adding the practical version: ask which lines are held regionally before you order in July.
powder at room temperature for a few days is usually a non-event
Small fix — refrigerated, not frozen, once it is in solution.
Which lane, and had it been quoted at that transit time?
ask what storage condition the stability statement was written against
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.
Disagree with the panic framing. Lyophilised material tolerates ordinary transit conditions far better than these threads imply.
regional stock removes most of this problem entirely
fridge, not freezer, once it is in solution
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.
Correction: that stability figure covers the lyophilised powder, not the reconstituted solution. Different claim entirely.
the door shelf is the worst place in the fridge
transit temperature is a distribution, not a number
