that was a bad idea bro, you can mix em in the same syringe but shouldn't mix em in the vial. Cuz you can't tell if they mix perfectly dose for dose. You might get one shot that's 80% test 20%Deca-Durabolin - nandrolone decanoate - -Durabolin - nandrolone decanoate - , and another shot that's the opposite. That was a bad idea bro. Are you still Gona try to run it? Probly cuz you dont wana waste that gear huh?
