Think of Amino Energy as a hybrid - it's the best of both the amino acid and pre-workout worlds. ON packed this amino acid supplement with the usual suspects, a mixture of muscle-repairing amino acids, and added a pre-workout spin by promoting NO production.
With only 10 calories per serving, a massive blend of amino acids and energy boosting ingredients, Amino Energy is the perfect 'pre-workout' that doesn't actually have to be used as a pre-workout.
Optimum Nutrition Amino Energy Recommended Use
For amino acids and energy, take one to two servings in the morning when you wake up. As a pre-workout, take as many as three servings about 30 minutes before your workout. For recovery, take one or two servings immediately post-workout. Remember: each serving does contain 50mg of caffeine, so don't take it too late in the day.
