I took the full sample of(2 scoops) about 35 mins before my workout after eating 2 hours prior. It was one of the better tasting pre workouts that I have had and I've had quite a few. I began to feel it after 10 minutes. It started with a slight BA tingle which I hadn't experienced in a while. By the time I got to the gym it had fully kicked in and i was ready to go. The energy was and I'm pretty stim tolerant. The focus was also high. The effects were stronger for me (in a good way) than 3 scoops of Jack3d and remained the same throughout my workout. This was also my first time using anything containing D-Asparic Acid so I'm not sure what role it played in the overall experience. I blasted through a very effective leg workout and added some abs at the end because I ended up working faster than usual. I ended up setting a new rep PR for squats. Great product and ill be using it again in the future. Thanks Lecheek.
