Nutrex research lipo 6? Is that even a question? I’m not even sure myself. What I am sure of though is that Lipo 6 is the bee’s knees. Nutrex lipo 6 120 just has the fancy “120″ tacked on the end, it’s not really any different than Nutrex lipo 6 or even Lipo 6 x. So what are you waiting for, get off your fat butt and buy this stuff. America!
