I bought a bottle of 250mg freebase nicotine juice from LNW a few months ago, kept it in a cool, dark place. I just opened the bag up yesterday and to my surprise the juice is pretty dark. Does that mean it's gone bad? Would there be any consequences to using dark nicotine juice like this?
Oxidation. Could taste off, and be a little weaker.
Mix up a small unflavored tester and see how it goes
It doesn't taste off or feel weaker from what I can tell with this first bottle I mixed with it. This is what it looks like: https://imgur.com/a/5kv6p9s
I had some 250mg that turned pink after a while. Still worked fine and didn't seem to tint my clear juices.
Doesn't appear to have much air space in there either. I keep mine in the freezer or fridge depending on stock
