Increased Pump, Vascularity, and Growth Hormone. Powerful combination of L-Arginine, L-citrulline, and L-ornithine. 

increased pumps & growth hormone
Argi-pump's tri-amino acid blend boosts nitric oxide levels maximizing blood flow and endurance while naturally increasing growth hormone levels and gains!

One of the quickest ways to see results every time you lift is through increasing nitric oxide. We guarantee you'll see an insane pump and vascularity within minutes.

Argi-Pump contains the purest form of L-arginine available, at high doses, ensuring your body is producing the max amount of nitric oxide possible. Argi-Pump also stacks two other powerful amino acids, L-citrulline and L-ornithine, to ensure optimal blood flow and endurance for bodies of all ages.


Without the right doses and forms of specific ingredients, supplements will fail to raise your nitric oxide levels. Don't be fooled by other company's marketing schemes; just because a supplement label has the word 'pump' in it, doesn't necessarily mean that your nitric oxide and blood flow will increase. 

To boost blood flow, the body's blood vessels need to be able to easily expand when needed (i.e. when you're working out) so that it can easily push more blood and nutrients to the worked area. Nitric oxide is a gas within the body that allows the body's blood vessels to be flexible so they can easily expand when more blood and nutrient delivery is needed, without having to increase your body's blood pressure.

Nitric oxide is produced through 2 separate pathways within the body. The urea pathway utilizes the amino acid L-arginine to boost nitric oxide levels, while the other pathway uses nitrates from food. Argi-pump contains high doses of the purest form of arginine to work within the urea pathway to boost nitric oxide levels. (Our products N.O. Chews and Crea-Nitric 100 use the nitrate/food pathway.)

However, as we age, the urea pathway becomes harder for the body to use if the amino acids L-citrulline and L-ornithine aren't present. This is why we've combined all three amino acids into Argi-pump's formula.

In addition, L-arginine has also been proven to naturally boost growth hormone (HGH) levels if taken before exercise and REM sleep.

L-Arginine Supplement for Bodybuilders Increase Blood Pumping
Kim Adams Lee

"I'm amazed at the difference these two supplements from Gains In Bulk really make during my workouts! I went out of town for a couple days and didn't bring these supplements with me and I worked out at the Hotel gym and the difference in getting in more reps and getting a good pump and just feeling more energized, were soooo noticeable! I felt so much weaker working out without these!! Needless to say these will be coming with me whenever I go out of town!!"
