I just got finished with another international trip and had zero issues traveling with T, HCG, and HGH. I also had the syringes in my carry on and they didn't say a word. I placed all of the meds in a pack for insulin and removed it from my carry on to go through the x-ray machine separately.
I've seen others ask about traveling with this stuff and this is the third time I've traveled internationally with it and it appears to be a non issue. I actually think political correctness plays into our favor here. They are probably told not to pick on people with health issues. HAHA..... Even in Seoul, where airport security is crazy strict, they didn't say boo.
Just to be on the safe side I do travel with a separate note from my family Dr listing all of the meds and that they are for legitimate medical purposes.
