I always use this while working out. It keeps me going and pushing through. The taste is delicious and make sure to drink cold. Taste better that way.

Creatin?

I like this product but the label does not show creatin although Sans club website says it does. I already take a creatin supplement so would like clarification on inclusion. Thanks.

Just as good as the cans!

I normally get the cans of the energy drink but thought this might be more cost effective. I used my sodastream to carbonate and mixed this in and it was so good!!

As someone who hates the taste of every pre-workout I have tried, I'm surprised to say this tastes great. It mixes easily and gives me exactly the push I need to get going. I will definitely be trying any other flavors they put out.

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!

Great in taste and efficiency!

[This review was collected as part of a promotion.] The smell and flavor of the amino energy is great! I do hope they make other flavors as watermelon isn’t my favorite. Not a large aftertaste which is a huge plus!

Watermelon, but with benefits

[This review was collected as part of a promotion.] Am I a skeptic when it comes to powders and supplements? Of course. I have been scarred before. But this? One sip and I was flabbergasted at how smooth and bright the flavor was. The package itself is great, easy to screw on the lid, and the little scoop being provided was helpful (not every powdered supplement does this, so count your blessings). It blended up wonderfully with my frother in half the amount of time suggested. As for the taste, it reminds me of a watermelon Jolly Rancher, with a slight fake-sugar aftertaste (the only reason I'll dock a star, as sucralose isn't my favorite). Honestly though, it's not bad and this powder comes with a plethora of benefits from electrolytes to amino acids that are great for those looking to boost their energy and recovery after workouts Would I consider buying this? Yes, I would. If you're someone in the market for a great pre-workout drink that boasts more perks than just caffeine, ON's Essential Amino Energy is a great place to start!
