@wecou Im no pro but I purchased what looks like a water bottle with a freezer pack inside. My thoughts are to pack many 3ml pen cartridges in the container labeled of course and bring one gansulin pen. Keeping a low profile through checkpoints and xray machines, as peptides could cause a concern for controlled substances possibly.
It even came with a thermometer…2 pens should fit and just looks like a water bottle.
