Energy + Aminos by Cellucor C4 is a light-stim pre-workout. A light energy drink in a tub, not a second C4 Ultimate. One scoop is 100mg of caffeine from green coffee and a 5g amino blend that includes 800mg of beta-alanine, plus BCAAs. No citrulline.
100mg of caffeine is an easy dose if a full pre-workout is too much. The tub is $19.99 for 30 servings, about $0.67 each. The limit is that there is no citrulline, and the beta-alanine is only 800mg inside the amino blend.
