H+Blocker, a new science in muscular performance is the world’s first carnosine synthesizer / muscle intensifier. During intense exercise, the release of hydrogen ions are accelerated in the muscle; followed by a simultaneous decrease in pH levels, (a process called “metabolic acidosis”), which is directly associated with muscle fatigue, weakness and ultimate physical exhaustion. This increase in H+ and decreased pH slows both the production of ATP - our body’s natural source of energy and inhibits the actual process of contraction with the muscle. New research indicates H+Blocker’s patent pending formulation increases the synthesis of carnosine. Two recent clinical studies have indicated that carnosine is preferentially concentrated in the Type II muscle fibers. This is even more apparent in the Type IIx fibers, which provide the fast-twitch muscle characteristics needed to propel world-class sprinters like Maurice Greene. Or, better stated to those who lift weights, Type II muscle fibers are what most of the top professional bodybuilders have more of, versus Type I fibers. This, in theory, might be why it could be easier for them to build faster, larger and more muscular bodies than the rest of us Carnosine is a dipeptide which binds to the fatigue causing hydrogen ions delaying the decline in pH and the onset of muscular fatigue. As a result, the total workload and intensity with which you normally train will now dramatically increase. For maximum results Isatori recommend using H+Blocker with IsaTest and the Maximum Growth program for a minimum of 4 weeks as the research shows the effects of H+Blocker significantly increase at the week level.
