After what feels like an eternity of research, ingredient discovery, sourcing missions and beta tests, we are finally ready to reintroduce the world to Cellucor® P6 Black™. The legendary anabolic has been reimagined and reformulated with the most effective, ground breaking pro-testosterone compounds and cutting-edge nootropic agents to deliver the first testosterone booster of its kind. P6 Black™ features Nootropic Testosterone Technology, a powerful combination of innovative testosterone boosting ingredients and cutting edge nootropics that deliver a hardcore testosterone supplement with an unmatched 'feel.'Alpha-GPC, a natural Choline compound, and D-Serine, an amino acid derivative, both support elevated cognitive energy, clarity, motivation and focus. These potent nootropics, when taken with pro-testosterone compounds help fully enable the body's anabolic potential, connecting mind and muscle unlike any product currently available on the market. What is D-Aspartic Acid (DAA)? D-Aspartic acid is a non-essential amino acid that, when supplemented with in appropriate dosages, has been demonstrated to boost testosterone levels, increase strength and support metabolic function. DAA works by stimulating the activity of NMDA receptors, which in turn leads to the production of a cascade of hormones that ultimately signal the body to initiate the process of steroidogenesis - the natural process of producing more testosterone. Additionally, stimulation of these NMDA receptors may also lead to the release of growth hormone. P6 Black™ features D-Aspartic Acid Magnesium Chelate, a novel form of D-Aspartic Acid, an ingredient that's been trending hot and picking up steam in the testosterone market. This new, innovative, chelated form of DAA features a fusion of D-Aspartic Acid with Magnesium. Much like Creatine Magnesium Chelate, when magnesium is chelated with an amino acid (D-Aspartic Acid) complex, it doesn't readily react with the stomach acids and instead gets a "free-pass" to the rest of the body for enhanced absorption.
