I am currently deployed, again, and see lots of soldiers buying no2 like its candy online? we just got our gym set up a month ago and its decent considering where we are. How does this no2 work and is it a sham or what? give me some feedback on this stuff . Here in baghdad its hot as hell and we do not know when we are coming home but the gym is the best thing that has happen besides the new chow hall. I am at the international airport and have not really had access to the net in a few months so I need some information asap. help a brother out....thanks RIZZO
