Traveling with Glucagon-like Peptides?

Been on the forum and doing my own research for a while. Most compounds I need are straightforward but chonluten is impossible - like finding a needle in hay. Manufacturers not making it anymore? Looking for easier alternatives that work similar. Any ideas?

Glucagon's counterregulatory role does make it oddly omnipresent. TSA doesn't share the enthusiasm though.

Small soft cooler with a freezable ice pack handles a week fine - sema pens are stable at room temperature for up to 28 days once opened, so the cooler is a precaution. TSA allows injectable medications with ice packs, no issues.
