Highlights from this day
- queue_position — if you are worried after a bad transit, test it. that is what the testing channels are for the practical risk in winter shipping is freezing, and in summer it is… 21:44
- ten_of_ten — do i need to worry about light exposure or is that overthinking 22:30
- amylin_amy — light exposure matters much less than temperature for these. i still keep them in the carton, thats one data point 22:35
- two_three_lifts — how long is reconstituted actually good for at room temperature 22:38

what temperature does a domestic fridge door actually swing to
i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine
is a five pound fridge thermometer actually worth it
freeze debate again

hand luggage
flying with vials, hand luggage or checked
hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct
a liquid cold pack tells you it was above freezing, not that your vial cooked
do i need to worry about light exposure or is that overthinking

door shelf or back of the fridge
a few hours at room temperature is almost certainly nothing. a week is a different conversation
light exposure matters much less than temperature for these. i still keep them in the carton, thats one data point

freezing reconstituted peptide is the one thing this channel has never agreed on, i could be wrong
unopened and in-use in the same place is fine. just keep the in-use one where you can reach it
update on the earlier thing does the fridge in a hotel room count as a fridge
powder is robust
[edited]i freeze aliquots and have had them test fine afterwards. others here would not do it and i understand why
