At 2–8°C, peptide storage is basically a tiny cold-chain operation, except the logistics department is me, a fridge thermometer, and a strict no-door-slamming policy. My GLP-1 vial has better environmental controls than some startups.

how much does door cycling affect vial stability?
quiet_pete @quiet_pete ·
does the fridge thermometer get its own logbook too, or is that where the startup analogy breaks down?
bob778 @bob778 ·
The thermometer is doing real work—fridge temperatures fluctuate most near the door.
mrfox @mrfox ·
Is the no-door-slamming policy enforced by fines, or just increasingly intense disappointed staring?
hockeybeer @hockeybeer ·
2–8°C is a tighter range than it sounds.

not sure the thermometer is actually in charge
maplemoose @maplemoose ·
2–8°C is a proper cold-chain range; the no-door-slamming rule is excellent.

Does a thermometer prove much about stability?
youngpixel @youngpixel ·
…and nobody talks about the power-outage contingency plan.

fridge got promoted
bpcguy @bpcguy ·
and the fridge door is usually the least stable spot temperature-wise. Middle shelf wins—apparently the vial gets better climate control than half the startups out there.

the no-door-slamming rule is mostly theater; opening frequency and how long the door stays open matter more than the dramatic closing technique. the fridge thermometer is doing the real work here.
