Product Overview

Black Powder is is one of the first pre-training formulas to employ the NOS up-regulating whey "peptide fraction" ACTINOS2IR, delivered with MRI's "Instant Release" (IR) technology.* You get the over-whelming advantage of a surge in nitric oxide (N.O.'s upper limit), combined with pre-workout compounds - delivered in ratios measured to precise gram-molecular specification.*

  • Strength and Intensity Support*
  • Promote Energy and Stamina*
  • Support Size and Recovery*
  • Encourage Focus*
  • Power and Pump Support*
The Science: Driving Performance and Size to New Levels!*

Nitric oxide forms the basis for both performance and size.* Nitric oxide dilates the blood channels which may support the delivery of vital training and recovery nutrients to your muscle cells.* In addition, nitric oxide is a molecule known to help "signal" and regulate muscle growth, muscle contraction, and metabolic adaptation to training.* Thanks to MRI's innovative ACTINOS2IR (Instant Release) technology, Black Powder may help to support an increase in nitric oxide levels.* Your body's performance and growth signals may amplify in both frequency, and duration.* Suddenly, size and training target sites light up!* Your strength, intensity, and focus find support they may never known.* Growth "signals" bombard your muscle cells with greater intensity, starting with your first workout!* That's why with Black Powder, you may help promote an outrageously intense workout, and you'll encourage super-dilated skin-ripping pumps to prove it!*
