So i just recently failed a drug test showing positive for amphetamines. The only thing i recently started taking was new preworkout. I bought a tub of shield supps gym candy, won a free tub of CL white flash, and had a bunch of different samples of pwo's that i tried so i have no idea which one it was. Just curious if any of you guys know what pwo ingredient might get flagged for amphetamines so i can make sure i dont take it again. I took a sample of Rogue Nutrition Battle Axe: Cuts that got me going pretty good and then i felt sick after a couple hours so i think it might have been that one but i dont know for sure and dont wanna pop dirty again. Also dont really want to stop taking stimmed pwo either lol. Any input will be appreciated
