Great product, you can really see the vascular results in this product.

Great product you can see the result really fast

I like this product due to its overall health benefits. Stronger blood circulation, decrease in rest periods between sets, and less DOMS off the top of my head. Achieved with only one ingredient at a fairly decent price and easy to take.

This is absolute awesome stuff but would recommend to take with N.O. Explode Version 3.0.....it makes me go crazy at the gym!!!

Pre-work necessity. Noticeable effects on daily routine. Really works.

I used Now L arginine to boost NO2 prior to switching to this product. This stuff blows everything else out of the water HANDS DOWN!!

I use this before workouts along with a pre workout, and works great for pumps. Price is great too!

I thought this product went great with my pre-workout supplement and truly did help to become more vascular

I noticed an increase in the pump I got when I stacked this with my existing pre-workout. I definitely recommend this product.

I have been using this product for about 3 months now and I can really feel an increase in my pumps when I stack this with my normal pre-workout. I usually double the dose to get a full 3000mg serving.

going through my first bottle seems to be working well with 5000 mg of L-Arginine and 500 mg of niacin

I read about how this product will increase energy levels. So far I have noticed without a pre-workout by taking this along with arginine I have just as much energy as I do with a preworkout. This may not happen for everyone, but it works that way for me.
