Well thank you for the supps again! I took 2 in total as I am a stim Junkie and knew what I was looking for. So experience...I took 1 to start..waited 20 min...not much...I took 1 more and 20 min later started my workout. The effect was awesome when it kicked in. Not a crazy jittery Berserker high but a focused clear motivation that made me WANT to rep more. I feel that this is the Samurai workout enhancer. Focus and energy not just rage and insanity. I say thi s because I still feel the effects..and if I was a Samurai I feel as if I could not only cut a baseball thrown at my head with my Katana blade, I could julienne it and catch it with the plate in my other hand. Props to AN. I will buy this to interchange with my other energy supps. Now to try it at work!!!!
