Untamed Labs Gorilla Pumps


There’s no better feeling than walking out of the gym with a massive muscle pump. Your muscles look fuller, you feel more confident, and you even manage to catch the attention of a few girls on the way out. Suffice it to say, when you have a pump, you feel on top of the world, only to realize that 30 minutes after leaving the gym, your once raging pumps have now deflated, leaving your feeling small, weak, and inadequate.


Wouldn’t it be great if there was a supplement that could pump you up during and after your workout? One that would keep you swole all day long and give you the look and feel of an IFBB pro.


There is one such supplement that has emerged from deep within the jungle. One that delivers raging pumps, superior nitric oxide production, and superior performance. Introducing Gorilla Pumps from Untamed Labs.


Gorilla Pumps is the ultimate pump-enhancing, stimulant-free pre workout powder that provides maximum pumps all day long. It can be used on its own or combined with your other favorite pre workout supplements. Morning, noon, or night Gorilla Pumps is your nitric oxide supplement solution.

Gorilla Pump Ingredients

Agmatine (1.5g)

For years, arginine was believed to be the key to enhancing nitric oxide production in the body. After all, it is the amino acid responsible for activating the arginine-NO pathway in the body. The problem, however, is that free form L-Arginine isn’t all that bioavailable, meaning it’s not really effective for enhancing nitric oxide production.

Agmatine is a derivative of arginine that has come to light in recent years as a superior N.O. booster due to its ability to indirectly boost nitric oxide production via arginase inhibition.[1,2] Arginase is a dastardly little enzyme in the body that’s primary goal is to destroy arginine. With less arginine circulating, you have less N.O. production, and ultimately less blood flow, vasodilation, and pumps.

However, agmatine puts the clamps on arginase activity providing for greater arginine availability in the body resulting in significantly greater nitric oxide output yielding hard, dense pumps that just keep on going, long after your workout is over!

But there’s more!

Agmatine is also a neuroregulator / neuromodulator in the body, which means that it’s able to enhance focus and cognition while training. This powerful compound even offers enhanced nutrient partitioning / glucose disposal abilities due to its role as an imidazoline agonist which assists in regulating insulin secretion.[3,4]

Gorilla Pumps includes a massive 1.5g Agmatine Sulfate per serving, a dose that is 3x greater than that contained in the average pre workout! Most other pump supplements would be done by now, but we’re just getting started.


Beet Root Powder (1g)


Gorilla Pumps enhances nitric oxide production not only through the arginine-NO pathway. You see, the body is equipped with two means for increasing N.O., yet most pre workouts only take advantage of the arginine-NO pathway by using ingredients like L-Citrulline or Agmatine. That’s not good enough for Untamed Labs.


L-Norvaline (300mg)

Gorilla Pump doubles down on the arginase inhibition with the inclusion of L-Norvaline, An analog of the branch-chain amino acid (BCAA) L-Valine, norvaline is a potent inhibitor of arginase due to its structural similarity to ornithine, an amino acid which itself is an arginase inhibitor.[11,12,13]

With arginase down for the count, N.O. increased by as much as 60%, allowing for better continuous nitric oxide production, giving you that feeling of being swole all day long!




Mix one scoop into your pre workout supplement and consume 30-45 minutes prior to training.


Pumps for Days!


The days of substandard or fast-fleeting pumps are long gone thanks to Gorilla Pumps. With its dual-action mechanisms for enhancing nitric oxide production, Gorilla Pumps ensures you get a pump quick and you keep it all day long. Look better, feel better, and perform better with Gorilla Pumps!

    This is by far the best pump formula I have ever used period! I’ve tried numerous brands of “pump” products and never really felt the pump. I tried this after reading some reviews about it on A1 Supplements and decided to give it a try. The first time I took this I mixed it with Adreanline Rush and headed to the gym. I had the best oh
