    Sick pumps, more vascularity overall on forearms, delts, traps, arm, and legs.

    For me, I noticed I was more vascular and better pumped during and after the workout when taking this. Better than any other brands I have bought. Great product, highly recommend taking.

    The pumps with this are absolutely insane. The vascularity is way more than normal.

    I want to start out by saying that I’m usually not a huge fan of Arginine. I just haven’t had great experience with it in the past. I’m naturally vascular, even when I’m heavier (~20% BF), so I’ve never really seen a lot of results from NO2 type supplements.

    That being said, I don’t know what it is about NO2 Pump, but it’s right there in the name: insane pumps! I’m not talking about that Tren lower back pump or anything, but I was doing low rows today and definitely felt like my lats were going to explode. And that’s saying a lot considering I’m quarantined in a hotel room with only a 53lb. kettlebell and some resistance bands.

    *I got this product for free with a previous order and if they don’t tack it onto my next order, I’m gonna throw a couple bottles in my cart. Good stuff!

    I have taken NO2 products in the past but never in pill form. I wasn’t sure if it would work as good as previous supplements but it proved me wrong. The pump that I got from this product was INSANE! My muscles weren’t fatigued but I had to take more breaks than normal due to the pumps being so intense that they hurt. Definitely a great product!

    “One of the best N02 boosters I ever taken”
    Took this N02 Booster for about a week so far and after two days I noticed a difference in vascularity. Now a week in an could hold my pumps for a while, which was something a struggled with. I tried many N02 supplements and let me tell you none of them work like this one

    Very good pumps. Insane vascularity when paired with S-4. Feels like Creatine in a way. I recommend! Makes arm day so much better.

    First week at one pill didn’t notice anything, second week started at two pills before workout or work. Notice increase in energy, focus.

    Best pump I’ve ever had as I’ve never taken a Nitric Oxide booster before. Definitely the real deal, would highly recommend for added blood flow to muscles and vascularity.

    Subject didn’t notice a difference in performance or vascularity. That is not to say it didn’t work as intended; subject just didn’t notice anything.

    Noticeable on arm days as far as vascularity, not much of a performance booster.

  47. 4 out of 5

    Eric Nazario (verified owner)

    To be completely honest I don’t know whether this is doing it’s job or not because of the stack I’m currently using, but I’ve had great results from everything else this far that I’d have to say I trust it’s contributing in some way. I’d recommend it for sure.

  48. 5 out of 5

    Alex Hernandez

    Subject didn’t notice anything until second week, @ two pills a day, 30 min before workout. Notice endurance up and more vascularity for sure. Subject is pleased with this one.

    This product will give you a better pump and a better overall workout experience, but there is a caveat. Citrulline Malate, according to the studies that I am aware of, only begins to give benefits in the 6 to 10 gram range. That means you need to take at minimum four-to-five of these pills for them to begin to be truly effective. That does not leave many servings per bottle and so the value of this supplement is questionable.
