After using Chaos and Pain Chemical 4 for 8 weeks as per label direction I feel I have gained a few pounds of muscle while losing some fat. My total body weight did not change, but I did consume about 2-300 hundred calories above maintenance level through out this cycle. My abs look tighter and vascularity is increased. Strength is up and I felt my mood to be elevated. The only negative is I believe it did dry my joints out a very little bit (just barely noticeable) This supplement is very easy to use (2 tablets a day) and I feel would stack Very Well with other Chaos and Pain products for even bigger gains.
