Ironfist is right,
I came back with 4 bottles of Cynomel though, I didn't know what was considered 90 days, and the 4th bottle was taken away. I brought back 2 bottles of Clen, which was stuffed with 200 tabs in each, and some clomid.
I got scared going to the secondary check, but it was nothing big. I'm heading back to TJ in December when I have a family gathering, will probably end up doing the same thing..
I'm too much of a puss to try to get back vials into the US.
