has anyone used this with a stack? did it do like most say it will as far as cutting up and getting rid of the fat and increasing energy? also. i have talked with some who say it is safe to use and not get busted on drug test for employers. we have random drug test for work. i don't do drugs. but i do steroids. and i know i am safe on the roids as far as testing goes. but i am no sure on clenbuterol. will that bust the test? i am thinking no. but i need to be 100 percent sure. so can anyone for sure tell me yes or no to that or where i can look to find out?
