“Essential AmiN.O. Energy is one of those multi-purpose products I can use in a variety of occasions. I truly enjoy it's multi-purpose use. Whether I need an afternoon pick me up, or am about to train or want to use it during my training to help keep my intensity up with its natural caffeine sources, I can use it for all of that and more. With some many flavors to pick from I definitely have options when I want to try something different. Finally being able to control the intensity of the product is huge plus, particularly if I am training at night and don't want a lot of caffeine in my system but just a light energy pump. Best of all, it's a low calorie product so I can stay lean and help build muscle simultaneously.”

“These are bar none the best tasting aminos on the market. They give me energy. They are great to sip on during a training session. They are also perfect for me to take to work and drink later in the afternoon for that mid-day lag. The best part is all of those beautiful little aminos are helping support my recovery. ”
