This is by far the best pre workout I have used as a division one athlete perfect for the early morning lifts. Makes the workouts so much more enjoyable.

At first. I wasnt sure about the flavor, but added it to my line up. Cant beat the energy you get from this product. Clean sustained energy and focus. After a few tries I decided The flavor is pretty refreshing !

Blue razz does not taste good. Pre works well with a good pump but i’ve tried orange and blue razz and they do not taste very good. other than that it’s a good cheap pre

Want to peel my skin off

Taste great amd good energy , however my skin os on fire ,feels like im wearing a wool sweater on top of road rash . It is agonizing . This last about 20 minutes and the longest 20 minutes ever. My husband tried it and it did the same exact thing to him.

It looks like a great deal but beware. I'm used to taking c4 I tried this in the first couple days it was fine but on the 4th or 5th day I broke out in hives. bad hives all over my body that itch. My wife and I have a newborn and it just sucks to have this happen. I will be returning these immediately. not saying you'll have the same reaction but I figured it was too good to be true.

Preworkout was great. Taste was very good and it’s not a very sour preworkout which I enjoyed. I hope there are more flavors to come soon
