This was my first time taking a crack pre workout, and I was not the same person after taking that pre. I started off on just about a a hair under a full scoop and that was around morning time with no food intake, boy did it hit me like a truck, after around 6 mins I was already ready to kill it, first 30 mins of my workout were honestly very euphoric but in the best way possible, I was so zoned in I was forgetting how many sets I had to do, once the full hour kicked in, I felt literally unstable as if I can push any weight, and well honestly I was pushing about 25 pounds heavier then I usually do, towards the end of my workout I was so zoned in a cracked out I did 9 sets of my chest pres workout, and I could’ve done them all day long, I felt like I had to need to just not stop. On the drive hoke the only thing on my mind was 2 things, 1. That workout was absolutely insane (chest day). And 2, I wanted to go back to the gym, I was so bored I felt like running till I could drop, after about 2-3 hours I just felt so great the feeling was just so great it. If you are thinking about buying this pre don’t hesitate, 10/10 on of the best I’ve ever had!
