First let me say that I am in no way affiliated with Nutristat, nor am I paid for writing this review. Started taking Bio ATP a week ago and immediately started seeing results. I'm taking, Pump script, Bio ATP and Purpeptide all together and the , and the results are truly amazing. Tonight I seen a huge increase in my bench press and as well as the rest of the products. Nutristat has done for me what other products haven't been able to do for me. If your serious about gaining mass and serious pumps this is definitely the products you wanna add. The only thing can about this product I don't like is there very expensive. If your will to pay the price you will definitely see the results fast. I highly recommend the investment !
