Well, I just had another batch of liquid barn nicotine oxidize on me after a few days of use and the bottle I have in the freezer is almost empty. I've been looking at switching to Carolina Xtracts since supposedly their nicotine doesn't touch air until you have it in your hands. Any one use them before? What other manufacturers is everyone else using?
I'm extremely low usage and it takes me a while to go through it so my go to is usually 48mg in PG and I get a 120ml bottle of it since I can't find any smaller.
Nude Nicotine was good but that wait killed me.

I'm still on the 120ml (100mg, 100% PG) batch of nicotine that I got from Wizard Labs in the beginning of December.  I broke it down into (2) 60ml amber glass bottles.  One stayed at room temp and one stayed in the freezer, until I finished the first bottle.  It's still clear and not peppery or anything.

I've read good things about Carolina Xtracts.  I saw a coupon code for them on Reddit awhile ago. Not sure if it's still good, but "Dada1".  It's case sensitive.
