[Failure] gel pack arrived liquid and warm. photos at unboxing.
Check-in as promised in the title: gel pack arrived liquid and warm. photos at unboxing. Seasonality, which the source-page lane tables show clearly once you look for it. The same origin, destination and carrier can differ by several days between February and August, and the temperature exposure differs by much more…
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.

Where in the fridge is it sitting now?
Cosigning the regional stock point. Ordering from a warehouse in the UK took the whole question off my table.
fridge, not freezer, once it is in solution
Disagree with the panic framing. Lyophilised material tolerates ordinary transit conditions far better than these threads imply.
Correction: that stability figure covers the lyophilised powder, not the reconstituted solution. Different claim entirely.
Agreed. The dry powder is the robust state; it is the solution that needs the care.
Is this a line they hold in regional stock or is it shipping from origin?
Powder or already in solution?
the excursion that matters is the one after reconstitution
Moved everything off the fridge door after reading a thread here and my temperature log immediately got boring.
Not convinced. A warm pack on day six is expected behaviour from a pack designed for four.
Split an order across two months deliberately to compare summer and winter transit on the same lane. Four days difference, same carrier.
Split an order across two months deliberately to compare summer and winter transit on the same lane.
Agreed, and a logger costs less than the vial you are worrying about.
lyophilised powder is far more forgiving than the panic threads suggest
