Nasty Juice replied to me the very same day, asking me to send pictures, which I did. I've just read their reply and they said that from the pictures they can verify that it is fake and that I shouldn't vape it, as it may contain harmful substances.
I suspected that it was fake and I haven't vaped it. It's going down the drain immediately.
They also asked where I had bought it.
I'm impressed with Nasty Juice at their prompt replies!
EDIT: This was not bought at a Chinese mall or at a fleamarket. It was bought at Mr Tobacco, Eden on the Bay, a few months ago (I forgot that I had it, as I still had some left in the current bottle). I'm so disappointed in them - I've always liked that shop.
You cant really blame them. Clones are made so well these days that its hard to tell even for them.
