power cut for 5 hours, fridge stayed shut, am i fine

the vial that visibly changed after a warm transit was the one that had already been reconstituted

freeze debate again

i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why

freeze thaw cycling is the risk, not one freeze. that is my read of it anyway

lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear
