Long time, no chat SR broskis!

I was able to score a bottle of this from my friend that works at GNC for a very nice friendly discount. Only paid $35. Hey, what's a few bottles of N.O. between friends right?

Let's get to the review:

This is my first review here please be gentle.

I've taken 2 NO Boosters in the past with fairly good results. (Nitrix, NO2 Black) I had finished a bottle of NO2 Black the month before and was looking to try something a bit different as I was not impressed with it. Anyways, this was explained to me...

No2 red is perhaps the best Nitic Oxide supplement I have ever taken...in pill form that is. MRI continues to impress me. Let's not forget it was MRI who was innovative with this type of product in the first place.

NO2 Black is excellent as well but it cost way too much and you had to take...

I just finished my first bottle of this and it was pretty good. First of all, I would suggest adding this to another pre-workout supplement product to gain the most from your workout. On it's own, you will notice better dialation throughout the day, but it doesn't give any amazing kick to your workout....

Hey guys how's it going? Nitric Oxide Boosters are always fun products to use, anything that makes your veins pop out more is always awesome. There are so many products out there, some work well, some don't. It's great to find one that works, seeing your veins more visible really helps you feel badass...also...

Where to start.. Ive taken NO2 Black and really liked that. If you have taken black before I felt very similar effects.

Pill Size--- Not too bad go down pretty easy with water and if they sit in you mouth for a few seconds you'll get a slightly minty taste. They're a little bigger than a L-glutamine...

Definitely increased vascularity and pump. But it doesn't really stand out above any other caplet form nitric oxide products. If you are looking for a good sustained release product make sure you use a caplet form, as the conversion of arginine to nitric oxide is about 26 seconds.

For background, this is the second Nitric Oxide supplement I have taken in pill form (NOX3 from Universal was the other) and I must say, overall, it is a decent product and better than NOX3.

-Potent product. The bottle says to take 3 in the morning, and 2 in the afternoon for an added "turbo...

I have used MRI NO2 Black and thought it was the best but this red blows it out of the water, my pump feels great and seems to last longer than the black. i also have high blood pressure and this has not dropped it to 120/69 was 135/89 but i also started a garlic supplement at the same time so keep that...
