I have been on Trac now for 3 weeks and can tell a difference in size and energy. I gave it 4 stars because i didn't feel it as much as i do No-Xplode. I took NO-Xplode for a year and had great results with it but i heard about Trac so i decided to give it a try. I had better pumps and energy with NO-Xplode. I will update this if it gets better with time. Overall great product though |
