Are these safe to take together?!

pretty sure you only need one of them, and space it apart when you take the next one that has a lot of caffeine/other stimulants, you'll give yourself an obscenely high heart rate

Definitely shouldnt do that. Your heart rate will go through the roof. With all the stimulants and caffeine in them it could be very dangerous. Might as well drink you a couple of redlines with a few 5 hour energy shots if your looking for heart trouble

Also, i would suggest trying muscle marinade, doesnt taste all that great but if you drink jack3d and can handle it then this wont be a problem. It almost gets 10s accross the board for mixability, focus, etc. Good stuff, actually gets you feeling kinda high when you work out :) My friends are huge and they suggested it to me. It definitely works

No. Not safe to take that much stimulant in one serving.
