As promised MusclePharm have released the formula behind another Arnold Schwarzenegger Series supplement, with this week’s product being Iron Pump. The supplement is set to be the brand’s entry into the pre-workout market through the gimmicky line, focusing more on the pump aspect of things, as opposed to energy, intensity, or focus. Right from the start we expected MusclePharm to turn to Hybrid N.O. for inspiration for the Arnold product. Which they have in fact done, but surprisingly not much as we predicted. Expectations aside, thanks to the formula upload from the brand we can confirm that Iron Pump features 10 main ingredients. With highlights such as the Hybrid N.O. star agmatine sulfate, arginine nitrate, and an ingredient never before used by the athlete’s company, vinpocetine. You can check out the rest of the facts panel below, and be sure to keep an eye out maybe this week or next, for another Arnold Schwarzenegger Series reveal.
