[Question] France — has anyone got a straight answer on packaging
Asking properly rather than in a comment on somebody else’s thread: France — has anyone got a straight answer on packaging.
Kept a vial at room temperature for eleven days by accident. Tested it out of guilt. It was fine.
Wrote the reconstitution date on the vial for the first time last year. Have never once since wondered how old a solution is.
Asked SWB which lines they hold regionally and got a straight list back. That answered my summer ordering question completely.
If two or three other people have done the same thing we might actually learn something. Alone it is an anecdote.
best — the order this archive was captured in
Merged into the seasonal thread for that lane so the reports sit together.
insulation buys hours, not days
Gel pack fully liquid on arrival, powder tested 97.2% against a claimed 97.0% afterwards. The pack had done its job for as long as it was designed to.
Yes — a logger in the box turns a fortnight of speculation into a chart.
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.
Lyophilisation removes the water that drives most degradation pathways. That is why the dry cake is comparatively robust and the reconstituted solution is not.
Same. Door shelf is the worst place in the fridge and it is where everybody puts them.
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.
Correction: that stability figure covers the lyophilised powder, not the reconstituted solution. Different claim entirely.
What was the packaging — rigid outer, gel packs, anything insulating?
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.
Careful. "The cold chain failed" is a strong claim and the evidence you have is a warm box.
Push back: you cannot infer degradation from a temperature excursion alone. That is what testing is for.
Agreed on seasonality. The same lane in February and August is not the same lane.
