i have never had a lyophilised vial fail after a warm transit and i have had some bad ones

how cold is too cold, can it actually freeze in a normal fridge

i log the fridge temperature daily and the room has never let me forget it

LU

nobody here can tell you a vial is safe. we can tell you what has and has not survived for us

buy a thermometer. mine reads 4.8 on the door and two degrees lower at the back

LU

anyone tested a vial before and after a bad transit
buy a thermometer. mine reads 5.6 on the door and two degrees lower at the back

how long is reconstituted actually good for at room temperature

TT

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

the practical risk in winter shipping is freezing, and in summer it is heat. plan for the season you are in

a liquid cold pack tells you it was above freezing, not that your vial cooked

my fridge is 4.8

freezing reconstituted peptide is the one thing this channel has never agreed on

LU

coming back after 16 months, is the pinned storage table still current

log it

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

freeze debate again
