I've been using Amplify 02 and Lipo Flame pre-workout for almost a week now, and I love this stuff. I noticed on the first day that the workout was much more intense and the pumps were incredible, but now after a few days I noticed that my pump just doesn't seem to go away. All day long I feel pumped, I love this feeling. Does anyone know if this needs to be cycled on and off, or if you can just take it year round?
