Nutrition Facts

One of the main ingredients that is almost always included in pre workout formulas is caffeine. Mr. Hyde contains 420mg of caffeine per serving. The caffeine comes from the following sources: caffeine anhydrous, d-caffeine malate, and caffeine citric acid. ProSupps Mr. Hyde has a strength matrix which contains 2.5 grams of beta alanine, 1 gram of creatine HCL, 500mg of arginine, and 500mg of L-citrulline. Next comes the Intensity Matri which contains 500mg of choline bitartrate, 50mg theanine, 50mg N-acetyl tyrosine, 25mg theacrine, 25mg gamma-aminobutyric acid (GABA) and 3mg of yohimbe bark extract.

Mixability and Taste

Mr. Hyde comes in a variety of unique flavors such as Blue Razz Popsicle, Cherry Popsicle, Pixie Dust, Cotton Candy, and Lollipop Punch just to name a few. I have had the Blue Razz Popsicle and the Lollipop Punch. Both are pretty sweet flavors that taste a bit artificial. The directions say to add 1 scoop of Mr. Hyde to 8 ounces of cold water. After mixing together, you are left with a drink that leaves you energized to power through your whole workout.

Just to give a warning. If you have no caffeine tolerance, you want to stay away from this product. This product will make someone sick if they are not used to consuming caffeine. If you are not sure, start slow. Consider taking a half of a scoop to assess your tolerance. This product is for someone that has plenty of experience with pre workout products and wants to take their training to the next level.
