I want to buy 5 gallons of bulk nic or 5 years worth. Don't know how much to buy or where to get it from. I buy juices that have 3 mg of nic at a 80/20 mix, sometimes 70/30. Nic River has gallon sizes at 3mg in a 50/50 ratio, would this work? I also don't understand what the difference would be going from 80/20 to 50/50. All I want is nicotine that is 3 mg like the juices that I buy, I'm so damn lost on this. I was planning on buy the nic, the pg and vg separately as well but it seems to be mixed already by Nic River. Any recommendations and or help with my purchase is greatly appreciated. Thanks.
