As a protein supplement nothing rates higher than whey protein in terms of biological value, nitrogen retention, immune system support and protein synthesis. The problem is, whey has limitations and nobody seemed to want to tackle the issue. After all, bodybuilders kept buying REGULAR whey, so why change a good thing that's working well? Bodybuilders never had the chance to buy something better than whey protein... until now. MuscleTech set its research and development team on the task of improving REGULAR whey protein. After four years of intense research, MuscleTech proudly introduces NITRO-Tech, the world's first nitrogen delivery technology. NITRO-Tech's potent anabolic and anticatabolic properties are due to three important complexes - Synthepro , Nitroxen , and Insulogen. These three complexes act together to help amplify the anabolic properties of whey protein by potentially allowing more amino acids to be shuttled into the muscles rather than oxidized, thereby helping to add more lean mass and strength than otherwise possible.
