vie takin no xplode, super pump, naNO Vapor, jak3d( which by the way is my fav)ect. as far as im concerned this is a good product good pumps increase in size, but it has alot of creatin so if ur cycled on n.o. and creatin i recommend lowering the ammount of creatin post workout.

I like this stack, could be a bit stringer IMO. Price was kind of high but like most supps you can get is cheaper if you shop around online. This one gives you a nice even energy throughout the workout and you don't crash. Good stuff but not the best. Taste is not bad at all. The only side effect was having to use tha bathroom about 30 minutes after consumption. this is pretty standard with any supp that contains arginine

I took this product and was impressed by the results. It gave me good mental focus, a good pump and I didn't crash afterwards. The energy slowly progressed and slowly digressed. The only drawback to this product is the price. MRI is expensive like Muscletech, but works a lot better.

I am now on my 2nd box of this stuff and I will tell you that it works great. I would recoomend this Black Stack if you are wanting to try the NO2 Black and the Black Powder without buying the regular sizes. NO2Black is great for the after the workout and the Black Powder is awesome while in the gym. I took the recommended dose on the box and have notice tremdous gains. I just starting taking WAR and ProNOS. Im a true believer on any of the MRI products!!!!
