Started taking this 3 weeks ago stand alone and working on a recomp. I have been eating clean but with holidays I have had my bad days! So far my wieght has stayed the same, but I clearly have lost fat! Much more vascular and this solid feeling that has kicked in the last few days is great! I feel good all day long, I have tried allot of products over the years, and I am a big fan of PES, but this stuff is making gains that I can really see! I will be runnig this agian with ther PR-XT, cant wait!
