MRI Performance NO2 Nitric Oxide Original Formula All Day Perpetual Pump Stim-Free Pre-Workout, N.O. Booster with L-Arginine Alpha Ketoglutarate AAKG, Power, Strength, Lean Muscle Mass & Vascularity

The product is actually good but it KEEPS COMING busted and its half powder!!!!!! Either mri has hired people that don't care or Amazon is continuing to decline.... MAYBE (PROBABLY) BOTH!?I need to provide an update and even response to others that had same issue, there MAY not be returns or exchanges but they sure contacted me to do just that!!! It was mostly powder but the product was great so I still took it so I had no need for refund or exchange so they WILL make it right!!!! I have an auto ship enabled and my second batch was still broke but MUCH BETTER, so i am assuming there was shipment errors on one batch they got, but since it's a pill and not a television i was able to make due and i'll re-update when i get my fourth shipment if they were all whole. Go ahead and order if you just care about the effects of the supplement but know they MAY still be broken in half.

I'm so glad MRI have brought this product back. This was my "Go-To" for many years back in the early 2000s. Iv tried many different No2 supplements since they stopped making it and nothing else out there compares. This stuff is awesome.***UPDATE***I was very happy to see that MRI had brought back their N02 Capsules. Obviously, I was quick to order when they did. Being that i have used this product since it first came on the market in the early 2000s, I am pretty familiar with the size, smell, taste, color, and consistency of capsules. My first order since their re-release was exactly what I expected and performed the way I expected it to. My most recent purchase however is concerning and in no way resembles the product I was expecting. First, all the pills are light, brittle, and already crushed up in the bottle. The color and consistency is off, the size and shape is off, as well as the taste. After maybe only about an hour of being outside of the bottle, the tablets will swell and explode into powder. I took 3 doses with literally 0 effect. I'm scared to take anymore because I'm not sure what this is.

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!

Love this stuff. Gone through 2 bottle so far and Incan still feel the pump. Big thing is to make sure you consume at least the recommended amount of water and follow the directions for your weight. The down side is that if your over 200lbs like me you will end up using the 180 count bottle in 10 days. But for me it’s worth it. Will definitely be subscribing to this. It will be worth it to save a few bucks.

This is very similar to the original formula that I loved way back when. BUT these pills came mostly crumbled, and there are no returns or exchanges. Impossible to dose with broken pieces, making the bottle useless. Good if you can get good product.

I used an O2 black a lot when I was younger in my 20s and working out. it was by far the greatest workout supplement ever created. However, based on the pictures, it’s obvious that this product is old and been sitting on shelves for a while. I ordered two bottles and they both showed up in this condition. Destroyed tablets, crushed and old.. avoid this product or avoid this vendor whichever

I used to buy NO2 platinum back in 2004 it was the best product around. Then an O2 red and black were out. They never worked as well for me as the platinum but they still worked slightly.This, however, is a huge scam. There is absolutely no arginine inside this product. You might as well put sugar pills. It’s a shame of company like this uses its name from the past, but just shows out garbage low quality crap. I would make a bet that if you lab tested this, there would be next to nothing inside of it. Just pills with filler powder. Absolutely zero results which I’ve never had before from any single and O2 product on earth. Even if this had 1 g of arginine in it, I would have some sort of effect. None. Zero. Scam stay away. This happens at times to supplement companies when they are way past their prime and they just try to capitalize on their old name.

No issue with broken pills or loose powder like some, but unsure of its efficacy. It says it's the original formula but I used to take the old version religiously and it both looked and felt different. The products with Citrulline tend to be better than just arginine. I might try the actual NO2 Black although it only comes in powder.
