Optimum Nutrition Amino Energy

I have been using this product since 2008 and have found nothing better to start my day with! Amino Energy is my morning coffee everyday. Mixes extremely well and the flavor choices have something for everyone, watermelon is my favorite. The combo of BCAA and 50 mg of caffeine per scoop gives me the comfort to give it to my 2 teenage sons for a pre Workout. I would recommend to anyone looking for a great BCAA product with caffeine.couple that with Supplement Warehouses great customer service and you can’t go wrong!
