I've been looking at the possibility of trying NOS inhibitors to help with mood, anxiety and hopefully pain. I found several listed in this article, including agmatine. But when I look up agmatine supplements, it seems like they are advertised to boost nitric oxide, not reduce it. What have I got wrong here? Shouldn't something that inhibits NOS produce less NO, not more? Any thoughts, @heapsreal, @Hip, @Mimi?
