Nitric oxide dilates the blood channels that deliver vital training and recovery nutrients to your muscle cells. In addition, nitric oxide signals and regulates muscle growth, muscle contraction, and metabolic adaptation to training. Until now, nitric oxide had a "pre-set" limit. Not any longer. Thanks to MRI"s innovative ACTINOS1IR, Black Powder creates an immediate surge in nitric oxide levels, 950% higher than previously attainable. In an instant, Black Powder"s performance/size nutrient complex floods your muscle cells in volumes never believed possible.

That"s why with Black Powder, you"ll get the most outrageously intense workout of your life, and you"ll have the super-dilated skin-ripping pumps to prove it!
