The Actinos IR "Instant Release" Training Effect
Pre-Training Formula, Powered by an Instant "Spike" of 950% More Nitric Oxide!

The Advantage: 950% More Nitric Oxide - "Instant Release!"
Black Powder is the first and only pre-training formula to employ the powerful NOS Up-regulating whey "peptide fraction" Actinos2, delivered with MRI's "Instant Release" (IR) technology. Now you get the over-whelming advantage of an instant surge of 950% more nitric oxide, combined with the most scientifically potent pre-workout compounds delivered in ratios measured to precise gram-molecular specification.*

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 Acttinos2 IR, 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. 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!*
