Today we’ll be taking a look at MusclePharm’s new pre-workout supplement called Iron Pump. It is from their newest line of supplements called the Arnold Series. This supplement is meant to be focused mainly on the bodybuilding “pump” and less on other common pre-workout benefits. I can’t honestly say that it comes close to matching up with MP’s other pre-workout – Assault. Nonetheless, let’s take a closer look.
Let’s start with the main focus, the pump boosters. They use a combination of L-Arginine Nitrate, Gylcine, Agmatine Sulfate, Beet Root Extract, Ornithine and Hawthorn Berry – that’s a mouthful! Though the science behind NO Boosters is still somewhat debatable – that list includes nearly every single ingredient suggested to increase Nitric Oxide levels which is pretty impressive. NO Booster’s like these have been shown to increase muscular endurance and reduce soreness following exercise.
A couple of other important factors: It does contain a number of stimulants including caffeine, choline, and tyrosine which will get you energized and focused before you hit the weights. As to the amount of caffeine per serving – I have contacted MP about this and am still awaiting the response. The prop-blend they decided to use with Iron Pump was a bit of a let down for me, because I have always talked highly of MP’s other products for great ingredient disclosure. One other thing to note is that Iron Pump is creatine free* so you will need to supplement with it separately.
In terms of endurance, Iron pump looks like it will do a decent job. It uses a number of B Vitamins, the NO Boosters, and Tyrosine to keep you going through your workout. It does not have any Beta Alanine which is what usually gives your skin that tingly feeling -but don’t be fooled : There is a fairly large dose of Niacin (Vitamin B3) which can also produce the same effect. Overall, Iron Pump is a decent choice of pre-workout supplement aimed mostly at someone looking solely to increase your vascularity (pump) during workouts, but I do think there are better options available.
