update from 21 months ago: replaced the fridge, temperature is stable, no more anxiety

does the amber vial thing matter or is it marketing

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

freeze thaw cycling is the risk, not one freeze. that is my read of it anyway

not the door

two to eight degrees. most domestic fridge doors are not in that range and people do not check

i would bin it

do you log the fridge temperature or is that too far

the vial that visibly changed after a warm transit was the one that had already been reconstituted

solution is not

New independent result logged — MKM, lot KP-0925, purity 96.8% (Medutest).

for the archive freezing reconstituted peptide is the one thing this channel has never agreed on, take that with a pinch of salt

buy a thermometer. mine reads 4 on the door and two degrees lower at the back

coming back to this light exposure matters much less than temperature for these. i still keep them in the carton

i log the fridge temperature daily and the room has never let me forget it
a liquid cold pack tells you it was above freezing, not that your vial cooked
