lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear
if you are worried after a bad transit, test it. that is what the testing channels are for

Highlights from this day
- swirl_not_shake — best travel setup for 21 days away with vials nobody here can tell you a vial is safe. we can tell you what has and has not survived for us 17:35
- swirl_not_shake — light exposure matters much less than temperature for these. i still keep them in the carton, from memory 17:37
- rae_labels — do you keep the unopened vials and the in-use one in the same place 17:51
hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct

i keep everything at the back of the middle shelf, never the door

log it
hand luggage
how cold is too cold, can it actually freeze in a normal fridge
a liquid cold pack tells you it was above freezing, not that your vial cooked
update from 26 months ago: replaced the fridge, temperature is stable, no more anxiety, take that with a pinch of salt
right so two to eight degrees. most domestic fridge doors are not in that range and people do not check
thats fine
genuine question unopened and in-use in the same place is fine. just keep the in-use one where you can reach it
freezing reconstituted peptide is the one thing this channel has never agreed on
lyophilised at room temp for 4 days in transit, worried or not
