I took Driven Sports RIZE yesterday. Just over 2 scoops (label recommends 1-2 scoops). It's almost frustrating because like other times for the first 30 mins I felt euphoric and on top of the world. I take preworkouts before leaving and walked to the gym with my gf and felt incredible. Then it soon faded away and I felt wired but not in a great way. You have to play about with this one a bit. Still a good product you just have find your right dose with it (heard anything from 1-3 scoops from people). With all the competition out there though I don't recommend this one especially due to the high price.

Tonight I tried one of my all time favs. That was just over 1 scoop of 5%'s 5150. I felt great this time and had an amazing workout. Solid energy, focus and pumps with no crash. Contains a lot of caffeine but no DMHA/DMAA which is good for me. It's been 2 hours since I got back and I feel good and relaxed. I rate this higher than 5%'s newest preworkout Kill It Reloaded.
