Hi Joe, they can get away from it because they call it "thyroid support", you can see that in the Ebay title above. This seller ships instantly, but it takes two weeks because it comes from Thailand. The Thyro-Gold I believe has thyroid gland made from grass fed New Zealand cows, and they also call something like thyroid solutions or something along that line. I've been buying stuff and other medications from overseas sources for ten years, often the packages are opened by customs, retaped and sent right to me. I've never had anything seized. If it were testosterone or crack or something wild of course it would be shut down, I'm not an expert on that sort of thing
