This stim shady is not imitating as a pre workout its invigorating. Great focus, decent pumps and a euphoric energy will have you vibing to your playlist as you kill your sets! In one word it is a FUN pre-workout. Not weak and not cracked out scary heart rate either. It tickles the sweet spot for sure. Bemoxie has the best price on it and ships it pretty quick so check it out before its gone from possible copyright issues!
