high quality and reliable product with very high e

[This review was collected as part of a promotion.] very tasty product for dilution with water, good texture and quickly dissolves when shaken. high-quality ingredients, the combination is very pleasant to the taste. very effective thing when you use it you already begin to feel a surge of strength and energy. very valuable product without any harmful things for the body.

This gives me the perfect amount of energy before

[This review was collected as part of a promotion.] I received this product for free from Influenster and Optimal Nutrients in exchange for my honest review. First off this stuff tastes so good I can't even, like a watermelon candy. I feel like it gives me the perfect energy boost before a run or workout! I really love the taste and the energy I get for this but it's not like too much energy it's just the right amount, sometimes things with caffeine can make you feel that rapid heartbeat and I'm glad this didn't make me feel that way. But did give me a little extra pep in my step! Love this stuff!

Workouts are superior!

[This review was collected as part of a promotion.] These work great for in the morning or before a good qworkout. I felt amazing with no harsh hangovers. It taste great with a nice watermelon flavor and it’s refreshing. I will be buying again for all my summer needs.

Taste good

[This review was collected as part of a promotion.] I have always liked Optimum Nutrition amino acids. They have a great flavor. Taste just like juice but without all the horrible stuff in it. The can is convenient for on the go. Gives a great amount of an energy burst without the jitters.

it's okay

[This review was collected as part of a promotion.] i tend to think these workout mixes are always too sweet, and this one fits that bill. but overall it's okay. i do like the watermelon flavor. and it seems to have a good mix of ingredients. i've like other products by this manufacturer and tend to trust them to use quality ingredients.

Great flavor

[This review was collected as part of a promotion.] This amino powder has a really great taste. It doesn't leave me jittery and I have noticed an increase in focus and energy. I'm not huge on working out or pre/post workouts but I would buy this product again.

Has a great taste

[This review was collected as part of a promotion.] Didn’t give me the energy I was looking for. Had a great flavor and for someone who never drinks water this a a great way to start. I did shake up that water instead of stirring and it worked just as well. The ingredients are way healthier than drinking an energy drink.

Very yummy

[This review was collected as part of a promotion.] I love the flavor of this! It's always an experiment to see how much powder to use without making it too strong or too weak, and so far I haven't had any problems. Just under one scoop in a normal water bottle works great. I like that it doesn't have much of a color, even after mixing with water.

Ideal choice for pre-workout.

[This review was collected as part of a promotion.] I've been using Optimum Nutrition AMIN.O. Energy and Electrolytes for over two weeks and it's the perfect balance of flavor and hydration I need. This makes it a great option for those who are watching their calorie intake or following a strict diet.

Love it

[This review was collected as part of a promotion.] I have used this amino energy for years. I was out of it for awhile and I noticed such a difference in my energy level - not just at the gym, but after. So glad to have this back! The flavor is great and it mixes easy with water
