"... Fairly decent strength nitric oxide products but nothing amazing compared to what is out there today. I didn't like taking so many capsules each day either, a bit of a headache and easy to forget."

"... Used both seperatly and felt excellent results, Love MRI. but I wouldn;t stack them both together as they do almost the same thing and you are better off saving money and buying either WAR or CE2 HiDef to stack. Would reccomend stick with the black powder and cut away the NO2, because they are big pills and timing them 30 mins before meals is difficult on a busy schedule. The thing I like about MRI brand is that they really deliver what they promise - so its worth paying a but extra (they're not the cheapest by far)"

"... I am really happy with the results from the black stack.. been on it now for about 3 months and have been making the best gains in years. I really appreciated the low price tag as well, cause as we all know these things tend to add up quite quickly! Overall, excellent.. highly recommended!"

"... Just finished up this stack a few days ago and I am so damn impressed with MRI. I haven't really touched this brand since the dawn of the NO2 days, but I am glad I gave it a go. I have re-ordered another 3 stacks and look forward to keep the gains coming. A+"

"... I've personally used no2 black and had excellent results. I was thinking of adding black powder to the mix so nice to have found this combo.. from what I've read and heard from the fellas in my gym - this is supposed to be the real deal. I'll post back full results and experience with this in a few weeks time.

Train hard!"
