Temperature logging: devices that record temperature over time let you confirm cold chain was maintained. Useful if a shipment was delayed or if you are concerned about excursion.

Picking up post #4: that is the part I would want checked first.
Shipping container and cold packs: reputable suppliers use insulated containers with cold packs designed to arrive cool. Checking on arrival that cold packs are still cold is a sign the chain was maintained.
Travel with medication: carrying a vial across borders requires planning if temperatures will exceed the range or if journey time is long. Insulated travel cases with ice packs are common solutions.
Freeze-thaw: some peptides tolerate freezing; others do not. Check your compound's labelling. Generally, repeated freeze-thaw is worse than single freeze-thaw.
This follows post #17 rather than contradicting it.
Reconstituted solutions: once reconstituted, solutions are less stable than lyophilised powder. Refrigerate prepared solutions immediately after preparation. Most stability claims assume refrigeration.
