test it
a few hours at room temperature is almost certainly nothing. a week is a different conversation

ok so two to eight degrees. most domestic fridge doors are not in that range and people do not check
hand luggage
i log the fridge temperature daily and the room has never let me forget it
freezing reconstituted peptide is the one thing this channel has never agreed on
lyophilised powder is genuinely robust. a warm transit is far less likely to matter than people fear
