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.

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!
