We don’t use proprietary blends. We have nothing to hide. You won’t find ineffective doses of any ingredients in BUCKED UP® because we know that you don’t want to pay for a supplement that isn’t going to work. Effective for serious athletes, bodybuilders, and anyone else looking for pump, focus, energy, and growth, BUCKED UP® is the pre-workout everyone can agree on. Approximately 200mg caffeine per serving.
