unopened and in-use in the same place is fine. just keep the in-use one where you can reach it

coming back after 13 months, is the pinned storage table still current

solution is not
Assay note: ERP lot KP-0925 reported at 98.1% of label content.
freeze debate again
sorry to jump in power cut with the door shut for a few hours is fine. a full fridge holds temperature surprisingly well

log it
not the freezer
i would bin it
i have never had a lyophilised vial fail after a warm transit and i have had some bad ones
lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear
for flying, hand luggage every time. the hold is not temperature controlled the way people assume
freezing reconstituted peptide is the one thing this channel has never agreed on
two to eight degrees. most domestic fridge doors are not in that range and people do not check

my fridge is running at 7.4, is that out of range
back of the fridge
a cooler with two gel packs held under eight degrees for eleven hours on a drive
if you are worried after a bad transit, test it. that is what the testing channels are for

i keep everything at the back of the middle shelf, never the door
the vial that visibly changed after a warm transit was the one that had already been reconstituted

buy a thermometer. mine reads 7.4 on the door and two degrees lower at the back
not the door
update from 22 months ago: replaced the fridge, temperature is stable, no more anxiety, ask me again in a month
anyone had a vial visibly change after a warm transit
thats fine
my fridge is 7.4
test it
lyophilised at room temp for 22 days in transit, worried or not
is a five pound fridge thermometer actually worth it

best travel setup for 14 days away with vials
unrelated but power cut for 7 hours, fridge stayed shut, am i fine
hand luggage
i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine
light exposure matters much less than temperature for these. i still keep them in the carton
the door swings four or five degrees every time somebody opens it. the back barely moves
