So the first thing I want to say is that the product itself is great. I was able to do my entire workout and had enough energy to probably do it again. Something that threw me off about the product is the flavor because it says its sour berry. However, the product is very sweet and does not taste like sour berry. The flavor of this product reminds me of skittles. Another thing to note is that although I did have a lot of energy I did not get the pump of the pre-workout like I would've expected. As in I did not seem to see an enlargement of my muscles. With all that being said It is still a great product for working out if you happen to have long workouts and need the energy.I bought the supplement to mix after snowboarding and mountain biking due to the hydration qualities, amino acids, and caffeine. I have celiac’s disease so I have to be cautious of new supplements that I take, Because I am gluten sensitive. I started taking this supplement, and I’ve noticed tell kind of messes with my internal workings. I looked at the label to see if any of the ingredients contained gluten and they do not. I also as the company if this supplement is gluten-free. They said it is gluten-free, but they did not send it out to get tested. I gave two of my friends a serving of this supplement, And one of them said that it also gave him a strange feeling in the stomach. People with Gluten sensitivities might want to stay away from this company, as I do have their sleep aid (tranquility) and that kind of messed with my internals as well
