This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.
On post #147 — agreed on the reasoning, with one qualification.
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.
post #151 answers the question as asked. The question underneath it is different.
Light protection: avoid direct sunlight and UV exposure. Amber vials or opaque containers reduce light exposure. For short-term storage, keeping the vial in its original packaging (often opaque) usually suffices.
Assessing an excursion: if a package sat at room temperature for a time, visual inspection (cloudiness, discoloration, particles) can alert you to problems. Not visible does not mean not damaged, but visible problems are a reason to contact the supplier.
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.
Worth separating two things that post #151 runs together.
Shipment during summer or to hot climates: consider shipping to a cold-storage facility rather than to home if temperatures will be high. Alternatively, time shipment to arrive when you can refrigerate immediately.
Reconstituted solutions: once reconstituted, solutions are less stable than lyophilised powder. Refrigerate prepared solutions immediately after preparation. Most stability claims assume refrigeration.
