- pinch_not_stretch — freeze thaw cycling is the risk, not one freeze. that is my read of it anyway, still working it out 20:22
- pinch_not_stretch — the practical risk in winter shipping is freezing, and in summer it is heat. plan for the season you are in 20:36
- pinch_not_stretch — hotel minibars are frequently not cold enough. i take a thermometer, which is ridiculous and also correct 20:38
- cat_on_the_tray — freezing reconstituted peptide is the one thing this channel has never agreed on 20:49
- split_dose_sam — the door swings four or five degrees every time somebody opens it. the back barely moves, still working it out 20:53
