MRI Reviews

	MRI N.O. Black Powder® Pre-Training Formula Orange Burst -- 1.7 lbs "I have tried many preworkout supplements and they all work about the same except this one. I am very detailed in logging every weight I push and every rep I do. I can always do 2 or 3 more reps or 5 to 10 more pounds when using Black Powder over NOxplode, Jack3d, and etc. Blue Raspberry is the best flavor but they all work the same!"

	MRI NO2 Black Powder™ Blue Raspberry -- 20 Packets "Pretty good product, felt a good energy burst and it was sustained through workout. Comparable to N.O. Xplode in my opinion, but cheaper." Posted by PhilM Rating:

	MRI NO2 Charger™ Vanilla Surge -- 2.5 lbs "Why use regular protein powders when an amazing product like this is available!
