I have used all types of NO products and right now I am using a fat burner
so I was looking for a NO product without any caffeine, so was at Wal-mart and thought I would give it a try. First time a I took it I had a little food in my stomach and the results were not all that great so I thought I would try and take it on a empty stomach on chest day. I got a little of a pump but nothing to write home about. It's a ok product. I know there are much better ones out there but I did not need the caffeine. First time users this would be nice.
