well first i gotta say, im usually dont have many veins, and this gave a few, and after only a like 3 days. on the fourth, my heart felt real funny, got some weird rashs and my breathing was a little more difficult then it should be. the product may work, but considering about 50 percent of people maybe more report bad side effects, especially ones such as heart palapatations, this product seems real sketchy to me. Not to mention the 60 dollars you have to lay out for the bottle, and the 4 pills id have to take. i even tried it a 5th day, only taking one pill and felt worse and the rash came back, so im deffiantly gonna just trash the bottle. its not worth messing with those kind of side effects if you ask me. but as for effectiveness..there is some pump, i dont believe 60 dollars worth though

Alright product saw results and was pumped up for the first week I took it but I had some reaction and started having heart palpitations and got a rash so I stopped but prob just me

This stuff was garbage. It got me pumped up the first few times after i took it. And thats was about. I didnt see any outstanding muscle growth or bigger pumps. And if you leave the pills out of the bottle they would start to corrode like metal. iffy product.

I got next to nothing out of this stuff. I remember about 2 years ago I saw it on the shelves of a GNC and I hadn't heard of it so I gave it a shot. I remember thinking the bottle was really cool after I got it out of the box but after I took it and went to work out I couldn't decide if I was getting anything out of it or not. I felt like maybe I was slightly more energetic than normal but I had difficulty assessing if that was just me. Whatever the case I stopped taking it and I didn't feel like I was missing out. I do think I have a somewhat high tolerance to stimulants so maybe if you can get a sample try it out but otherwise I'd go with Jack3d or some other pre-workout.

these things were pretty wicked,, it comes in pill bottle that makes it look illegal but as far as theactual product they hit you really good but dont do much for a pump, tons of energy though

Hello,
I used the product for about 3 weeks without any side affects until few days ago I felt terrible dizziness and many red spots on my body and my body got really hot my fingers got big! . I stopped it and will never use it again

i like this product it works for me i now have to take it with food which lowers its effectiveness but i was getting rashes and itchys which is fine it says on the box it might happen.... oh yea absolutely HORRIBLE smell to it but sweet tasting caplets lol i dont get it. oh well try it on SALE way to expensive not on sale i got mine on the expiration so... a lil more cheaper

all these NOs seem to work different for different people but i has very good results with this one. i stayed focused and got great pumps.

for the first days i was getting really huge pumps and training intensity and i was really focus i didnt mind taking all those pills but i stop using it for a while because i was having a competition very soon and i rest like 4 days after and when i wanted to get the same feeling i didnt get nothing i was feeling the crash and no pumps and energy i say well maybe i need another day to get use to it again and no didnt feel nothing only crash

Again, I purchased this not being aware that MAP=MuscleTech. Tried this overpriced and disappointing nitric formula with little results, and was pretty disappointed with this product along with my other MAP purchase, Arson. Do yourself a favor, skip this product. Your workouts and your wallet will thank you. Small pump, big price, big let down. It does something, just not enough of it.
