Now you can reach unprecedented levels of strength, energy, focus, intensity, stamina and power.  Black Powder provides ingredients that impact your ability to recover quickly and efficiently; driving muscle growth to new heights.  This is the result of MRI's quest to develop a precision-calibrated training formula.  The technologies in Black Powder "light up" a stunning array of metabolic targets to help power and amplify your workouts for optimal performance.*

The Science: Driving Performance and Size to New Levels Scientifically, nitric oxide forms the basis for both performance and size.  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 ActiNOs2 IR, Black Powder creates an immediate surge in nitric oxide levels, 950% higher than previously attainable.†  In an instant, the performance/size nutrient complex in Black Powder floods your muscle cells.  Your body's performance and growth signals amplify in both frequency and duration, starting at your first set!  Your strength, intensity, and focus hit levels they've never known.  Your recovery starts before you even leave the gym.  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.!^*
