I'm not sure what you are asking
@puffon; cost, mfg., or ???
If you are asking about cost; currently a liter is running
$44.99.
As to who is manufacturing it; I don't know. They do NOT state that it is U.S. made the way they do with their "premium" so it could (likely?) be foriegn/import. I could find nothing in the MSDS, or GCC, they have posted on their website (linked above). I don't know if they are buying overseas and simply repackaging, or buying pure concentrate (1,000mg/mL) and diluting and repackaging, or doing something else altogether.
I do have 2 liters of it and
find it to be the smoothest/most transparent of the three nic bases I have tried (Wizard Labs, RTS, and Heartland (non-premium)). I am NOT a nic connoiseur, so don't give my opinion much weight, but I have been quite happy with Heartland's offering. I think it is worth trying at least a sample size if you are shopping.
