Ground Breaking Full Cycle Nitric Oxide Optimizer. Sustains Peak Power & Delays Onset of Muscle Fatigue, Formulated With Nitric Oxide Precursors, With Dual NOS Upregulators, Helps Buffer Against Arginase, Supports Muscle Protein Synthesis. FULL CYCLE PERFORMANCE. NO2 BLACK FULL CYCLE - A new chapter in the legend of NO2 begins. From its very inception, NO2 BLACK revolutionized performance supplementation. Now, after years of dedicated service, the classic NO2 BLACK formulation has been fully upgraded. This is everything you expect from NO2 BLACK...and more – much more! FULL CYCLE NITRIC OXIDE OPTIMIZATIONNO2 BLACK FULL CYCLE drives NO optimization on four powerful fronts; feeding, fueling, protecting and generating muscle. Here is how it works: First, the L-Arginine precursor, L-Citrulline, effectively "feeds" more L-Arginine into the NO – production matrix. Second, premium sources of L-Arginine provide the "high-octane" base that fuels NO conversion. Third, L-Norvaline helps combat the Arginine-converting enzymes to help support greater reserves of NO fuel. Fourth, the NO generating NOS "factories" are upregulated on two fronts, yielding up to 1250% more nitric oxide. THE QUAD CYCLE OF TRAINING PERFORMANCE. The name says it all; NO2 BLACK FULL CYCLE™ - the power of the NO2 Black legacy formula, "super charged" to impact the full, quad cycle of training performance. Before a workout even begins, muscles are primed for performance by nitric oxide induced, nutrient-surging blood flow fueled by NOS upregulators and NO precursors. As the high-intensity phase engages, key nutrients help delay muscle fatigue, amplify workout capacity and sustain peak power. Then, L-Carnitine and Grape Seed Extract help drive skeletal muscle bioenergetics by promoting efficient fat-to-fuel conversion and oxygen utilization. Before the workout comes to a close, protein synthesis has already engaged – preparing muscles for optimal post-workout recovery and growth.
