everyone has this NO2 thing wrong, it is really a wieght loss supp- as someone posted before, this is how it works:
the NO2 molecule seperates the $ molecule from the pocket cell......
thus actualy making you lose wieght!!
save your $'s and invest in something that actualy is proven to be effective, like some ethel ester creatine.the long term effects of NO2 usage can be very detrimental to your health, and aside from the "pump" it does nothing for mass or strength.
