I\'m close to 20 on that scale, but haven\'t got any pure none product so I don\'t know. A date-mate or something similar (approx 3 nol 1 none) that was good when I tried it last fall, doesn\'t seem to work well anymore. Got some bad OD-reactions (same dose as previously used) with women at clubs acting real bitchy last week. I had borrowed the bottle from a friend, and it seems the scent has changed. There\'s nothing left of the musky part that was quite dominating back then. Instead the scent is now kind of sour. Isn\'t that what none smells like? I was thinking maybe the spray-bottle isn\'t very tightly sealed and the nol might have oxidized to none?? Has anyone else noticed similar things with older nol-products?
