I order controlled substances from overseas all the time. I have recieved 2 of those stupid letters from U.S. Customs. I tear them up! I have not had any problems! The only way that customs is going to "show up" at your door is if they intercept 10,00 vials or some other massive load! It is not worth their time and effort.When I got my first letter I had 2 other packages on the way, and they made it through. By some SMALL chance, they show up, Slam the door and laugh! Mike
