GMS Portable Syringe Case - Perfect Travel Insulin Carrying Cases for Pre-Filled Syringes - Keep Medication Safe and Secure (Bundle of 2 Cases - 1 White and 1 Black)

I would, and have many times, prefill the syringe and put it in a carrier like this: https://www.amazon.com/GMS-Portable-Syringe-Case-Pre-Filled/dp/B0786TRW3M And then stop worrying about it and take it with me. The drug is good for a long time at room temp. I know this is not a popular method and any number of things "could happen" but they wont. You will be fine.
