I really like the taste of Amino Energy, and it gives me a nice boost without feeling too intense. It mixes easily and works well before a workout or when I need a little extra energy during the day. Overall, a convenient addition to my routine.*

Love the Strawberry-Lime flavor. It dissolves quickly. I take one scoop in the early morning hours with half glass of water before I head to work. It keeps me focused and energized all morning. *

Drinking Amino Energy really does give you a boost of energy. Just make sure you do something physical like working out or bike riding or any kind of activity to make the supplement work better.*
