Product Overview

  • Real World, Clinically Tested Levels of the Key Vasodilating/Nitric Oxide Inducing Ingredients*
  • Redefining the Whole ‘Pump’ Experience*
  • Maximize Pumps to feed muscle and enhance recovery
  • Stimulant Free
  • It Flat-out Works. First Time, Every Time.

Pump It Up

There’s no feeling in the world like a crazy pump. Once you’ve picked up a barbell and blown up your arms, you’re pretty much hooked for life. It’s the holy grail of the extreme training experience. How pumped can you possibly get? There’s nothing like the feeling of totally engorged quads, or shoulders so pumped you can’t fit through a door. That’s why we designed MUTANT PUMP.*

Open The Floodgates

How good your pumps get depend on many factors. One major factor is how much Nitric Oxide (NO) is in your blood. If you can find a way to raise the NO levels in your blood, you will also experience a much crazier pump than before. So MUTANT has created a formula that helps to open the floodgates, and allow an unreal amount of vasodilation to occur. Here comes the PUMP!*

No Bulls#!t

MUTANT knows that you don’t have the time or patience for nonsense. That’s why we pack the MUTANT PUMP formula with REAL WORLD, CLINICALLY TESTED LEVELS of the key ingredients. Other products often contain ineffective doses of effective ingredients. However, our capsule contains the FULL DOSE of intensely concentrated HYPEROX, to raise the pump to new levels. We believe in this formula because it’s tested by actual MUTANTS. We’ll gladly put our capsule up against anybody else’s, anytime, anywhere. The ingredients that matter, in REAL WORLD CLINICALLY TESTED LEVELS. It flat-out works. First time, every time.*

Stimulant Free - For Maximum Flow

You read that correctly. MUTANT PUMP contains no stimulants. So you get the absolute maximum vasodilation effect. There’s nothing to stand in your way when it comes to getting a mind blowing PUMP. We don’t want any road blocks along the way. We have one thing on our minds, helping to creating MUTANTS, one PUMP at a time.*

Mutant Pump Formula – Quick Science & Research Notes:

  • Vasodilation and PDE5 enzyme inhibition are related to enhancing the natural physiological process of NO (nitric oxide) cycle.
  • HypyerOx® is a specialized fenugreek extract with 2 in-house studies reporting it to have statistically significant vasodilation properties1.
  • L-Arginine is an amino acid, a known vasodilator, multi-patented for nitric oxide (NO) uses, and helps promote protein synthesis.
  • L-Threonine is an essential amino acid that assists in the building of lean muscle tissue/mass when combined with regular weight/resistance training and a healthy balanced diet.
  • Niacin contributes to normal functioning of the nervous system and helps the body to metabolize carbohydrates and fats.
  • Magnesium (gluconate) helps to maintain proper muscle function.*

This product has no effect on me, just a little bit of energy after 50 minutes. But nothing to be noticed.

Takes a little while to kick in, but after about 40 minutes I can feel the difference it makes. Kinda sucks you have to take 7 pills though, maybe they should make it a powder, or more concentrated so it's less pills per serving.

For the moment, I would rate as 10 ingredients it contains. I'm still not taking, because I'm taking nitrix BSN, and I do not like such combination of supplements. When finished using the nitrix, I will start to use this product and then I will classify

This supplement is expensive and does nothing except make you smell like rancid meat soaking in a trashcan full of old soy sauce.
