This supplement is literally the best thing I've had on the market right now in regards to energy and focus. DMAA has been my favorite ingredient for years for the sole purpose of getting me amped to hit the gym. The addition of nitrates is just the cherry in top because I don't have to look for a separate pump product to go along with it. I've had Blue Bomb Pop, Pink Lemonade and the pineapple flavor. All of the flavors have been great and I would recommend this pre-workout to anybody! Just don't take it too close to bed because it will keep you up!
