I have been using Amp 02 for two weeks now. My only regret is that I didn't order the two other products for the stack. My friend I go to the gym with uses NO explode and one day I let him use Amp and I tried his No Explode. I felt the difference and so did he. We both liked AMP better. Once he is out of his product, he is going to switch to AMP. Next time I order, I will get the stack. Amazing. Thanks Omega
