Just saw a thread on evo where a guy tested positive for some drugs after using some preworkout, I think jack3d or something like that. Should I be worried? Just started using dspark preworkout.
bro dspark doesn't have any DMAA....that's what that guy tested positive for....
DMAA in Jack3d is Methylhexanamine // 1,3-dimethylamylamine...which will make you test positive for amphetamines sometimes....
