Strip NCI don't know if anyone has already mentioned it but GNC sells a pill you take the day before along with a lot of water that works.
Just go in and tell them exactly what you are looking for, come in a small box like sudafed or whatever.
If they are going to do randoms though do yourself a favor and don't even apply as you will get caught sooner or later.
