34Reports submitted to this wiki that mention temperature control most often mention the state of the coolant on arrival. That is a weak observation: a pack can be solid on arrival after a period at ambient if it was frozen at dispatch, and can be liquid on arrival without the contents having exceeded the intended range.{{r|reports}}34Reports submitted to this wiki that mention temperature control most often mention the state of the coolant on arrival.

+36== How much it matters for a lyophilised peptide ==
+37Degradation rates in the dry solid are much lower than in solution. A lyophilised peptide is considerably more robust to a transit excursion than a reconstituted one, and short excursions at moderate temperature are unlikely to produce a measurable change.{{r|ich_q1a}}

+39This is not a reason to disregard the cold chain, but it does bear on interpretation. An unfavourable [[Third-party testing|independent result]] on material shipped without temperature control is weak evidence about the supplier, because the material's history is unknown — the asymmetry described at [[Chain of custody]].
