Anyone have any suggestions for a good pre-workout supplement or combination of supplements that have very little/no caffeine? I've been taking White Flood by Controlled Labs and am fairly satisfied with it but I'm trying to cut down my caffiene intake. I work a lot of nights so I get enough caffiene through other sources in order to make it through my shifts. I'd like to try to cut down on my caffiene intake in order to avoid developing too high a tolerance to it. Any suggestions will be appreciated, Thanks!
