hcg travel

Has anyone travel by airplane with their TRT and if so can anyone give advice on travel without running into problems.

I really like this one. It keeps vials cool for about 1.5 days. http://smile.amazon.com/gp/product/B000VD3BX4?redirect=true&ref_=cm_cr_ryp_prd_ttl_sol_18

I prefer to keep my HCG refrigeratored and I'll be without access to a fridge for a couple days. What I'm wondering is if it would be safe to transfer some of my HCG from it's vial into an old HCG vial, could this cause any sterile issues? As long as I'm using a new needle and wiping both tops...
