the door swings four or five degrees every time somebody opens it. the back barely moves
powder is robust
freezing reconstituted peptide is the one thing this channel has never agreed on
door shelf or back of the fridge
while im here i left a reconstituted vial out overnight once, sent it for testing out of curiosity, it came back fine
follow up i keep everything at the back of the middle shelf, never the door
for flying, hand luggage every time. the hold is not temperature controlled the way people assume
my fridge is running at 6.2, is that out of range
test it
not the freezer
best travel setup for 24 days away with vials
a few hours at room temperature is almost certainly nothing. a week is a different conversation
hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct
parcel sat in a hot mailbox for 7 hours, is it dead
quick one i log the fridge temperature daily and the room has never let me forget it
anyone had a vial visibly change after a warm transit
two to eight
i would use it
i left it out overnight by accident, bin it or use it
follow up is there a difference in stability between the compounds
anyone tested a vial before and after a bad transit
