u/thermal_mass_tom
A cold box is thermal mass plus insulation. Most kits get the insulation part wrong.

comment on [Failure] gel pack arrived liquid and warm in July. photos at unboxing. in c/coldchain · 176 points · 3 days ago
The specific failure here is almost certainly thermal mass rather than insulation. A single small pack in a large void has nothing to hold the temperature with; the pack exhausts and then the air in the box does whatever the outside is doing.
Two smaller packs plus a snugger void outperforms one bigger pack in a loose box, and it costs the same.
comment on [Paper] survodutide MASH data is the most interesting hepatic readout in the class in c/survodutide · 43 points · 3 days ago
Rodent data is rodent data. Dose scaling is not linear and the models tell you what to investigate, not what to expect.

the other thing a logger shows you is your own fridge. i put one in mine for a week expecting to be smug and found 2.1°C at the back and 7.8°C in the door.

Titration speed is a side-effect dial far more than an efficacy dial.

Stalled for 8 weeks, changed nothing, and it started moving again on week 38.

comment on how many independent tests before you trust a vendor. my number is three in c/vendorvetting · 73 points · 10 days ago
Disagree but this is the good kind of wrong — it is specific enough to be checked.

Not to be pedantic but order records and PeptideMeter are being used interchangeably and they are not interchangeable in real life.

This order history matches mine almost exactly. Same vendor, same timeframe, same result.

Slight fix: the number was 97.6, not 98.3.
Disagree on that part. 98.1% and 98.9% on the same vial is normal.
