Yes you can bring Clomid, Nolva, Arimidex, Clen, or anything else you can find except AS.
My advice:
If you do bring over some aux. meds and claim them don't have anything else on you.
They typically will search your pockets and do a tap down when you claim aux. meds although I have
come across before with a bunch of stuff and not gotten searched.
P.S. Limit your score to a 90 day supply only - or they could claim that you are importing for profit and then they could confiscate your stash.
Good luck!
