Great addition to pre-workout supplement, a little bit gritty to mix though.

This stuff works!

I noticed results within 5 days or starting this product and have been able to cut out coffee completely. I also wake up earlier with more energy and feel like it is benefiting my journey to gaining healthy body weight. For the price this product is amazing.

Very interesting, definitely useful on dull and dreary days!

Posted by 5249498575345316039 on Feb 18, 2016

I've been having a lot of motivation problems lately, but not anymore! When I take this I feel euphoric for a couple hours, and then just plain good for most of the day. Best to use it only when needed though, as I have found the effects aren't as strong or beneficial if taken daily.

Made in China

Posted by Reviewer2411412 on Jun 28, 2015

So disappointed this product is made in China. It doesn't say anywhere on the iherb website. Thought it would be the same as the other now products. You need to clearly inform people, had I known is was a product of China I would never have purchased. Waste of money.
