This flavor is fantastic. I also drink the tropical twist which has been discontinued and that flavor is fantastic as well. Mixes well, tastes great, loaded with amino’s and a bit of caffeine. Great stuff and a good deal at Sam’s.

My husband and I feel energized and alert after drinking Optimum Nutrition Amino Energy. All of the flavors are grea, and the powder mixes well with both water and tea.

Great product, hydrates great and tastes great

Love Amino Watermelon. This is my daily lifeline. Just the perfect dose of what I need to keep my energy pumped.

I love this stuff. It really helps with energy, and feeling 'ready' to do stuff, without any side effects. I actually got my husband to start drinking it, because it works (he doesn't 'believe in' all my powders %26 supplements). We drink it just about every day. I barely drink coffee anymore. The flavor is too strong for us, so we use about twice as much water, but otherwise it tastes yummy. Wish they had the other flavors in this bigger container!

This is a product that I regularly use and was happy to see it at Sam's at half the price I normally pay.

I love this product. I've been using it daily for years. It's a great way to start the day. No jitters or tingling like the other drinks out there. I love the way it wakes me up and gets me going. Flavor is excellent and this price is unbeatable.

This is very easy to take - dissolves well in water, and tastes incredible, no matter if I use 64 oz of water or 16 oz. Reasonable price at Sam's. First time buyer but sold for life!

Good mild pre-workout energy and focus boost with amino acids — not super intense. Great if you want smoother energy without heavy jitters. Provides noticeable energy and focus for workouts or as an afternoon pick-me-up Great value from Sam's Club

Love this stuff! Love the price! Drink it almost everyday instead of coffee. Problem is that they dont carry it at my local Sams Club, and sams doesn't ship to Hawaii anymore. Had to order and ship it to a family member in the mainland and then ship here, but that cost an arm and leg. Please bring it to Hawaii Sams Club!
