10/10 ENERGY WAS UNREAL
5 out of 5 stars
10/10 ENERGY WAS UNREAL
This was only my second time trying nitric oxide and let me tell you…. This stuff DOES NOT disappoint. I used it in the morning before the gym and felt like I was on another level !!! I had such a good pump- I was quite literally drenched in sweat! I proceeded to move into my new home for the rest of the day after that and realized at 6pm that I hadn’t stopped once all day, or had a lack of energy at all after heavy lifting for hours on end.. then I remembered I had taken the oxide in morning. Unreal endurance from this! 10/10 if you’re looking for something to keep your energy levels UP for hours 🙌🏼

    This product is very beneficial for anyone who likes to see a good pump in the gyn! Not only does it give great pumps due to the additional blood flow it gives but it also helps with nutrition digestion! and for someone who struggles with stomach issues and digestion problems, with this product I had no "bloating" or "feeling full" during my workouts. I would take it 30-45min before I train along with my pre workout meal as it is best to take with food. They do not have to be utilized for only pre workout though as they are helpful with just digestion in general! Overall great product for offering more then one benefit in just one supplement.

    Not 100% certain it give me the pump, maybe because I have tried more patient stuff in the past and my body just doesn't notice this, can't rule out it doesn't work, I get more from creatine and pre workout, to be honest. Probably good for beginners tho

    I never thought to ever give this a try, and I am so glad I did. I have been consistently using these for 3 weeks and the pump I get at the gym is crazy after starting to take these before I workout! I have also noticed I no longer feel the "gym sore" as long as I used to, so I feel these very much help with muscle recovery. My workouts have gotten so much better, adding this to the ruthless pre-workout that this brand also carries!

    Reviewed in the United States on October 16, 2021
    Verified Purchase
    I bought this to replace this product: https://www.amazon.com/gp/product/B0769GXC4M as it did an amazing job of giving endurance and pump during a workout. Instead of 3-4 sets of reps per exercise, I was able to do 5-7 sets and felt like I could just keep going. It was insane.

    I tried other NO boosters but they all sucked so bad I resorted to using an expired bottle of the one I linked above as a 2019 bottle of that was way more potent than anything else I bought here until I found this Iron Brothers brand. The ingredient types and amounts are damned near identical so I gave them a shot and so far they are working great! The only thing missing is beet root powder but in its place, Iron Brothers' has proanthocyanidins, which are a class of polyphenols found in many plants, such as cranberry, blueberry, and grape seeds which I understand to essentially be a type of flavonoid which are great antioxidants. All in all, I'm very satisfied with this product!

    4.0 out of 5 stars Solid product, reasonably priced!
    Reviewed in the United States on March 5, 2023
    Verified Purchase
    IronBroz seems to be one of the few NO2 boosters that I can actually feel working. When my ‘go-to’, (NO2 Black by MRI) disappeared, I started trying different NO boosters, with very little luck. When NO2 Blk finally resurfaced, they had almost doubled in price, so I decided to give one more random company a try before going back to something I knew had worked for me. IronBroz has been a pleasant surprise! At 51, I’m not quite as hardcore in the gym as I used to be, but this seems to give me that extra little ‘push’ I remember getting, and had been missing, from NO2 Blk. Will definitely buy IronBroz again..
