Mix up Essential Amino Energy anytime you want a fruit-flavored or coffeehouse-inspired boost of energy and alertness. You can determine what's appropriate for any situation, adding a 2-scoop serving to water for an afternoon pick-me-up or increasing the amino acid matrix to 10 grams with a 4-scoop pre-workout energy supplement that delivers 200 mg of caffeine from green coffee and/or green tea extracts.
