Mix up essential amino energy anytime you want a refreshing fruit flavored 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 15 grams with a 6-scoop pre-workout strength supplement delivering 300 milligrams of caffeine from green coffee and green tea extracts. The level of support is entirely up to you.
