I read the articles on NO2 and i think i understand most of it but i was just wondering if there are any potential health problems if you take it. I undstand that it basically doesnt work and is over rated but i was at the local supplement store and the guy was trying to get me to buy it but couldnt really tell me much about it. Thanks
Typical supplement-store shagoff pimping stuff he knows absolutely nothing about. You seem to already acknowledge the fact that the stuff is overrated, if not a complete waste of money. I don't know enough about it to comment on any potential adverse health effects, however.
