If you go to Juarez, visit "La Farma" and see Mike. Most pharmacies won't sell roids to you. "La Farma" is near the "market." Just get in a cab and tell them you want to go to the "market."

If you want to be totally safe, the best way to smuggle in Juarez is to go on a Thursday (before 5) and buy your shit. Then go to a bar and get fucked up until the clubs open. Then go to the club and party your ass off. Then when you cross the border (@ about 2 am), you'll be crossing with hundreds of drunken college kids and they won't check you. (I promise)
