I am a college football player and this year they started drug testing. We had to go to a presentation on it and they talked about supplements and how you will fail the drug test when taking most of them. They went on to say that creatine is not a banned substance, but showed pictures of supplements like NO explode, Animal stack/pack, and other popular supplements out there that would fail a test. What is in these that would make you fail a drug test... I know too much caffeine will fail you but caffeine works its way out of the body quickly and they would be testing us at dawn around 6 am and we workout in mornings around 7 in the offseason. I was just wondering what is really safe out there. I have taken xceed before and would like to get on somthing to help me get bigger once the season is over but does anyone know exactly what is Safe to take where I wouldnt have to worry about failing a drug test? Any help at all would be great thanks
