Use this handy nic supply calculator

The rest of the comments, especially the one about the calculator, are super helpful. I just wanna add that the best way to store nic is in an amber Boston round bottle topped with argon and with a polycone cap on top. Most places don’t list the neck finish so you’ll have to email them. If you’re ordering bottles from River (as you should because they’re dirt cheap and high quality) the neck finish is 20/400 so make sure to buy that size cap. You can find both the caps and the argon for pretty cheap on Amazon :))

Depends on how much you vape. I believe there is a calculator out there that'll do math for you but I can't remember the name. Someone else may have the link.

That's 12mls of nic for every 100mls you make. How long does a 100mls last you? A week? 2 weeks? Longer? If the answer is 1 week then 12x52 = 624mls per year. If it lasts 2 weeks then it's 312mls per year.

I vape 3mg if I buy store bought but I diy alot and vape 1.5mg so I have around 2,000ml of 100mg and I have always put them in the 120ml or 150ml bottles thwy come in from each manufacturer...I have some rs nic some lb nic and some lnw nic but atm im around 2,000ml....whoever is telling you not to bulk buy and freeze your nicotine is dumb.its simple really,with whats going on with vapemail bans and in my state they are trying to pass a 28% increase per ml on eliquid containing nicotine which came out to around an extra 10 cents a ml on most brands.at a local shop the owner im good friends with said its going to make eliquid next to un affordable at a vape shop in our state so im glad ive been diy'ing for awhile.but whoever told u not to bulk buy n store dont listen to them cause they will be the ones looking to buy nicotine in 6 months from now.

>If you have the freezer capacity get a couple gallons. 300.00. ish. I mix for 2. Around 18-24mg nic. MTL RTA. I'm back to what I started with, but, much better quality. Teh Kafun 2019. It is a tank. I drop my vapes a lot. I have yet to damage 1. Dropped minimal 50 times. I'm not proud to admit that. It pisses me off. I carry at least 2 wherever I go. Why? I just asked myself. Idk why. I have Aspergers, ADD and stuff. I get out of chair, , vape falls. lol They get stuck under my gut. I like tanks that can take a drop well, and mods. I stalked up. I have the big boys if I want clouds. I don't like to have to clean my glasses non stop. And the vape from clouds gets all over my shit. :-) I'm 61 been vaping 11 years. I will Vape till I die. The vape shipping ban is BS. I think we can get supplies from china. If not, synthetic nicotine will be an option. Good, but expensive. So 2 gallons should last a me awhile. Thank you calculator link guy. I will hit it now. :-) It really pisses me off that I'm "forced" to give up my right to vape. They want me to smoke and die. smfh According to the calculator. two gallons will last about 4 years. Any suggestions on storing in large bottles, Jars? Are the 500ml plastic bottles ok to freeze it in? I know I can google it. I'm doing my best to avoid, boycott google. F google. So now I have to type my search. lol

Does the mail ban apply to liquid nicotine as well? I thought it was just vaping specific products. All of the products in vape are available for other applications.

Maybe it is better to not buy liquid Nicotine for longterm Stocking!
