4ALLFAMILY Nomad Medium Pro Insulin Cooler Travel Case – TSA Approved Medicine Cooler with Biogel Ice Pack & Temp Display – Portable Diabetic Cold Case with Insulated Medicine Bag - Pro Turquoise

I use this one if I'm 24hrs or less between refrigerators. It uses a gel pack https://a.co/d/0esUDM7k If I'm traveling overseas, I use this one as it can use either a gel pack or a USB powered cooling sleeve. Note that the cooling sleeve can use up a 20,000mah powerbank in 12 hours so being near a USB charger plugged into an outlet is best. The gel pack lasts about 36 hours. You cannot have both gel pack and USB cooling at the same time as they pot occupy the same space. https://a.co/d/07dnMLQl If you want the cheapest solution, then a regular insulated water bottle with syringes in a waterproof plastic bag surrounded with ice works.

They. Don't. Care. I just came through TSA about 5 hours ago. They did want to look at my med cooler. I said "Meds". They nodded, opened it, glanced inside and handed it back to me. They are looking for bomb making stuff and such. They couldn't care less about peptides. Edit: I have this one. https://a.co/d/0gWLOvaB And this battery powered one. https://a.co/d/0fEISySr
