Introducing the Bucked Up BLACK series... 
Ever find a song you couldn’t imagine being any better, then its remix drops and blows your mind? Bucked Up BLACK is the pre-workout version of that. Everything you love from our staple pre-workout formula -- pump, focus, energy, hydration, endurance -- but with a twist. We added humic/fulvic acid, a mineral blend that helps detoxify the system and promotes healthy nutrient absorption. 
BONUS: It actually turns black.
