If you really wanna bring it check it in. I flew back to Ireland today from Holland and like always I threw a few vials in my check-in luggage.
I had 1 full kit of HGH, about 10 needles and syringes for the week, 1 vial of eq, 1 of prop and 1 of tren. They are NEVER checked. I have done the same to America too and no problems. Never try bringing it on the plane though just in case.
edit: as I remember, once or twice my bags were searched and a green slip was attached to the bag saying it had been checked but nothing was removed. That happened going to America with roids I believe.
