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.

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!
