I used NO2, and all the hater garbage posted about it does nothing to discredit it at-all. All of the Nitrous Products are tried and true, that includes MRI's NO2, NOExplode from BSN, Anavol, Muscle Nitrous by VPX, and Hell even MuscleTech's Pump Tech. Here's my 2 cents on the people who so dilligently claim it's bullshit:
I seriously don't know what they were expecting. What I see selling this stuff on a daily basis is that people REALLY expect miraculous results from taking things like NO2, Esterfied Creatine, blah blah blah. They expect to be lean and hard, stronger than they've ever been, have endurance out the Yin Yang, and all of this inside of 2 months. Expecting miraculous results, from anything, is just plain old childish.
NO2 does exactly what it's supposed to do. It increases blood circulation, and in 3 years I've met maybe 4 people who said they didn't feel ANY difference, and I am willing to lay odds that two of them were lying and probably got bitched at by their wives or girlfriends or parents for the money the spent on it.
Keep in-mind, the Supplement Industry comes under a TON of scrutiny because of the lack of FDA backing, contrary to how many people hate the FDA, everyone believes it when some Agency likely acting on behalf of either Government or Competing Companies releases a claim that so-and-so supplement is worthless.
Bottom-line, try the shit for yourself and see if you care enough to spend the money on what it does. Don't expect Jesus Christ himself to descend from the Heavens and give you a wink and a thumbs-up as you pop open the bottle.
