Well I have switched to a new product. I believe this is the best one so far. Definitely doesnt fit the bang for buck. But the best quality for sure. I also dont rate preworkouts on how " high" I get. This one gives me the best punp and lift the most weight for longer. Nutrabio pre workout and they also make a stim free one I have been using a few hours before bed and its great. Nutrabio makes a great product and will be switching most of my powders to them.
