Today I finally took the stim pre workout. I emptied the caps into about 8 oz of water and shook it up. Mixed very well, no particles. Taste was gross I have to say. All I tasted was artificial sweetener. Really couldn't tell the flavor at all. As for results I just didn't feel anything. It was as if I had not taken a pre-workout at all. With the stim free pre I feltfocus but it made me a bit tired. With this one I didn't feel anything. Sorry Athletix, I do appreciate the free sample but I'm just being honest with my review. If I could have mixed the stim free one with a strong stimulant product it would be a great addition. Anyway, thanks again to Athletix for letting me try it out.
