I was wondering how do you know if the winny is real by looking at the bottle . Cause i have a 20ml bottle and when i bought it some stuff was stuck at the bottom and top and then when i shook it up it dissolved but i know from the other bottle of winny that i had you could see it separate from on the side of the bottle. Can anyone help me out with this and tell me if i have some legit stuff cause i can't tell or maybe i have to let it sit because it is still foamy.
