MRI Performance NO2 Nitric Oxide Booster, Original Formula with 3,000mg L-Arginine & AAKG for Strength & Stamina, Supports Nitric Oxide Production, Healthy Blood Pressure & Heart Health (90 Caplets)

I truly believe in this product not because of the benefits for muscle growth but because I have poor veins and I do work out. I have been using this product for a little over a year now. I have better circulation and better color in my legs now. Plus it helps with awesome pumps from your workouts. Great, great product for me. Love it,and I get a couple dollars off because I use the subscription. I do highly recommend this product. But remember if you have medical issues you should always check with your Doctor before trying something new. Along with your own research you can make an informed decision on weather this product will be good for you or not. Hope this helps. God bless 🙌 🙏

Finally, the original formula came back, I enjoy this supplement because it just boosts everything I do in my fitness goals, so far I have been using it paired with intermittent fasting (a huge window ) and very light workouts slowly building from just a few sets to a half hour a day. I have gone from 250 lbs to 235 lbs in 2-1/2 to 3 months while building muscle. This has improved my recovery times and nutrition absorption and boosted my energy levels as well as my libido. When I was younger and I first took this supplement my Main Goal was to Build as much muscle as possible and I added a solid 15- 20 pounds, but now that I'm older it's more about leaning back down. The goal is getting back to my Marine fighting shape lol. I have also got my wife on this and she reports losing 5 pounds so far ( even tho she's only done a workout here and there) but she reports her energy levels at work have also improved and her figure is toning up nicely since she started 3 weeks ago. We both only take the morning load so far and are working our way to a healthier lifestyle. I recommend this to anyone looking for that extra boost in recovery and nutrition absorption.

I was a loyal customer back in the mid 2000’s when it really worked. Didn’t see it around for a while. Saw that it was back and ordered it.That was a mistake. When I opened the bottle I saw broken tablets, loose powder and noticed that tablets were not coated but had a rough powdery surface. The original style used to have coated tablets that allowed the rather large tablets to slide down your throat. These new ones are hard to swallow because of the rough surface. The worst part is, they didn’t do anything for me. I actually felt like I had less energy not more. I guess nothing is as good as it used to be. They don’t accept returns based upon a claim of safety reasons. I don’t think that’s the real reason. So, I threw them in the trash. Don’t waste your money on this current version of the product.

I was hesitant as I used to use this years ago and went straight to the reviews. I expected to get a chalky mess and was thinking this was the old stuff that had expired since I had a bottle before that I had in a storage unit long past the expiration date. Remember how good this paired with any pre-work out I went ahead and gave it a chance seeing that more recent ratings had claimed the issue with the capsules being broken and chalky were solved. As I get back into shape I am noticing it's impact more and more. The pumps are more insane like they used to be and my pump is sustained throughout my workout and then some. Let's hope they continue to improve the quality so that everyone who purchases this gets the same quality product.

Big horse pills, sometimes hard to swallow.

I had one bottle in 2023 have the pills breaking apart many of them down to powder but have not experienced a single pill behaving in the aforementioned abhorrent manner across many orders of both the 90 and 180 count variations. `ActiNOS CFM Nitro P` (ActiNOS) (you'll find it labeled in several way comprised of said naming convention) is realistically the most effective means of propagating the production of nitric oxide that you can just grab (for the time being) from Amazon or platform akin to it. MRI is one of the very few companies/formulators to have consistently (all the way back to when there were the silver topped Black Powder products through products like NO2 Black, NO2 Red, NO2 Full Cycle, Pro-NOS, etc.). They took a turn for a while years back and originally dropped its inclusion in the re-release of black powder which I hope they never do again (worst business decision they could make; ActiNOS is what drives the insane pumps and resultant performance induced by their products). During that dark time of `new` black powder (without ActiNOS), I periodically called up one of the the lead chemists at Glanbia (at that time) begging him to sell me drums upon drums of raw-powderized ActiNOS but private sales were always a no go. This is to say please, MRI, never drop ActiNOS from your formulations again!

bought for my workouts as I have previously used this product from GNC. upon arrival all the pills with crushed in powder or in pieces. bought a couple times thinking it was just a transport issue, but the second order was even worse. would recommend purchasing this product from the store or elsewhere.

I don’t normally leave reviews on supplements but I really am glad MRI has stuck to their tried and true formula. Seems like over the past 10 years or so supplement companies have really dumbed down their formulas…not sure it it’s because they are afraid of litigation or they just want to save $$$, but point being it’s become difficult to find supplements with unique formulas that actually work. I know Citruline is all the rage these days for pump products but to be honest I always got much getter results with Arginine and Arginine-AKG. Part of me wonders whether or not Citruline is just a cheaper ingredient….I understand it’s supposed to be a “pre-cursor” to arginine, but in my experience, it’s better to just take the thing directly instead of taking something that “converts” to what you want. Anyways, I got a real vein popping pump from this product taking 5 caps twice a day, for the first time in a very long time. It also increases pumps to the ol’ johnson. Works. Just buy it.
