Never really considered an intra workout supp as I find plain old water to be quite adequate. Tried free sample of purple wrath and was very impressed. Always factor in placebo effect but i did set a PR in this workout so I will give P Wrath the benefit of the doubt. I also noticed that at the end of the work out I had much more energy then normal. I work out in mornings so this is definitely a good thing! Good product guys! Taste was VERY good as well.
