Has anyone had issues with taking supplements across the border? I'm flying to Mexico stopping in the US. I have only taken a small package of supplements before. I would like to stick to my program and bring a ziplock bag of vitamins, fish oil, creatine and hydroxycut. I also would like to bring some protein powder and glutamine. I don't want to spend an hour explaining each pill at the airport. Thanks for your help.
P.S. What should I bring back?
