Not for everyone

Returned this right away as it has cognatiq that gave me light head and also hyper and unsettled till I took an antidote. It's not for people on blood press medications even if it's a low dosage.

Thanks for trying Amino Energy + Focus! Check out regular Amino Energy which does not have Cognatiq! We recommend speaking with a medical professional when introducing new supplements to your routine!

Delicious pre workout

[This review was collected as part of a promotion.] I loved this pre workout. Flavor is delicious, but male sure to put a lot of water. It’s easy to mix and gives you a boost of energy. It is also good after a workout.

Good for hydration

[This review was collected as part of a promotion.] Optimum nutrition, amino, energy, watermelon, splash hydration powder is great for those super hot days when water doesn't feel like it's doing enough. Having the added green tea, extract and green coffee, bean extract really helps with some added energy.

Tastes Great!

[This review was collected as part of a promotion.] This works great as a pre workout! I usually don’t like drinking a ton of caffeine, but this works as a great little boost if I need extra energy. The taste is great too. I would definitely recommend.

Delicious, Effective Pre Workout

[This review was collected as part of a promotion.] The Optimum Nutrition AMIN.O. ENERGY+, Watermelon Splash amazed me with the delicious flavor and the great boost of energy it gave me each time I used it! I don’t have a shaker, but it was very easy to mix with just a spoon or a straw. I used this multiple times before going to the gym, and it gave me lots of energy to get through a workout. I also love that it has zero sugar. It is definitely the best tasting pre workout I’ve ever had.

Works well

[This review was collected as part of a promotion.] Works super well! I use this before a work out. I take it about an hour prior and it’s a nice replacement for me for pre workout. It doesn’t taste bad. And it doesn’t leave a bad after taste in your mouth either.

Really good, doesn’t clump

[This review was collected as part of a promotion.] While the flavor of this drink is a little underwhelming, I truly appreciate that this particular brand focused more on the impact of the actual content of the nutrition powder versus sugary taste. I truly feel alert when drinking this.

Not the worst but not my favorite

[This review was collected as part of a promotion.] This hydration and energy mix is pretty good. I find it mixes really well without leaving chunks of powder. You can tell it has caffeine because it definitely perked me up after drinking it. Nothing crazy but noticable. Flavor wise I was not a huge fan, if you like that sweet overly fake watermelon flavor this may be for you. Reminded me of a watermelon jolly rancher flavor.

Taste great & feeling ready throughout the day!!

[This review was collected as part of a promotion.] This watermelon Amino Energy hydration powder by Optimum Nutrition taste great and gives me a bounce throughout my day!! The taste is not sour and not too sweet but just right!! You add the powder to your water, shake and enjoy!! I’ve used this for about a week now and can definitely feel how the electrolytes and caffeine keep me energized to take on whatever the day may throw at me. I would definitely recommend giving this a try if your an on-the-go type of person.
