If anyone can please provide some input it would be greatly appreciated. I have 2 vials of Winstroll (10 ml each, exactly packaged the same). 1 looks exactly like I've always seen winny (milky white), but when the other is left sitting, the milky white part sinks to the bottom and the top just looks like dirty water. When I shake it, it still doesn't give off the same milky whiteness as the other. Is that normal? Can I still use it?, also both are expired by a month but all I can get my hands on. Any advice?
