Okay, but wouldn’t buy

[This review was collected as part of a promotion.] The powder has a good flavor, but it is too powdery. It’s really hard to mix with a spoon…with it being so dry, it clumps together once you add it to water. I prefer a more refined powder. Not tested for heavy metals I believe, so that may be something to look into.

Love this mix, the best watermelon flavor by far!

[This review was collected as part of a promotion.] I use powdered amino acids/pre workout daily, so I was excited to recieve this product. The taste is phenomenal, they nailed a true jolly rancher watermelon without being too sweet & just the right amount of tartness. I dont notice it at first, but as I drink on the mix does get that chalky taste/feeling at the end. For the value, its definitely worth it. The size is generous & it did give me a great bout of energy.

Tastes great, doesn't agree with my anxiety

[This review was collected as part of a promotion.] I really wanted to love this pre-workout. It's super yummy and has plenty of caffeine to get me motivated for my morning workouts. A little bit after drinking it, my anxiety started kicking in and I got heart palpitations. After looking it up, I think it's a reaction to the beta alanine. Not worth it for me, but if youre okay with that ingredient definitely give this one a try

[This review was collected as part of a promotion.] When shaken in a bottle of water this mixes very well. The flavor is amazing!Has a true watermelon flavor! Not that sweet artificial watermelon taste. I absolutely love this before a workout. I’m able to keep my stamina though out it.

Tasty energy

[This review was collected as part of a promotion.] I am one who definitely needs my caffeine in the mornings. I absolutely love the watermelon flavor and surprisingly the 100mg of caffeine is just enough to get my day started. Just scoop into a blender bottle add some water and go on with your day. Love the convenience of not having to make coffee when I’m not feeling it.

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.

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.

Watermelon wave of energy!

[This review was collected as part of a promotion.] My husband loves this brand of aminos so when I saw this brand was an option for my campaigns I knew it was the perfect opportunity to try it out myself. This product incorporates energy and hydration making it a great value as it combine what would normally be two products. The watermelon flavor is delicious and mixes well. My husband even tried it and likes this upgraded version from the brand.

Tastes great

[This review was collected as part of a promotion.] This tastes really good and gives a nice little boost. I used it before a run and wasn't as sore as usual thanks to the amino acids. I was also happy with how easily it mixed. I couldn't find my shaker bottle and it dissolved just fine with a spoon in a glass of water.
