I noticed there was a 3rd version and have been waiting for someone else to post something about it here, basically so I could see what /u/abdada had to say. Can't PM the bastard so here it is...
"ARMOR v3 incorporates one of our newest additives, ascorbic acid, whose anti-oxidative properties allow for the reduction of free radicals in solution. Thus, slowing the oxidation of your active ingredient – nicotine – without affecting the taste of your finished product!"

It looks promising. And if does work, it seems likely we could DIY our own ascorbic acid solution to stabilize other brands of nicotine.
the addition of ascorbic acid has been known to science for almost 20 years: http://www.ncbi.nlm.nih.gov/pubmed/10600424
Juul (by Pax/Ploom) adds benzoic acid to emulate cigarette smoking's nicotine hit more. Ascorbic acid is an antioxidant (vitamin C!) which may offer a different end result in nicotine metabolism -- it might actually help reduce withdrawal cravings in between vapes.
It seems like an elegant solution to the problem of oxidation. Can you think of any potential downside?
I haven't looked into this in probably a year. From my vague recollection of the source research materials, I believe AA can increase cotinine in the urine which could be problematic if you have nicotine testing at work. If the case is that the body metabolizes more nicotine when AA is involved, it might mean lowering your nicotine strength as well.
I don't see any downsides unless AA causes sediment and coil gunk, which I doubt as I've added AA to e-liquids before without issue.
Do you think this could be a viable solution for long term storage if paired with other methods like freezing and oxygen displacement? I know your standard advice is to dilute and store properly but in the not too distant future it might become necessary to buy larger quantities of nic that will end up sitting far longer than normal.
Ascorbic acid is cheap but I'm not sure how easy it is to work with.

The last paragraph states ascorbic acid enhances nicotine receptor binding by 30 % at 25 nM or 4.4 ng/ml. No idea if there is more or newer literature on this.
If NN uses ascorbic acid as an antioxidant it's probably much lower in concentration anyway.
>free radicals
Thank fucking god I hate free radicals messing up my nic
I charge $25 per radical, they're never free. Dude.
So, can anyone chime in as to whether my next purchase should be NA v2 or v3?
I have v2 currently (vacuum bottle with luer slip seal) and I find it pretty much perfect. Every month or two I take it out of the freezer and transfer 30mL into a squeeze bottle that I just store in a box.
It works very well for me that way. I do notice slight discoloration toward the end of the 30mL bottle, but not enough to bother me.
So is there a reason I should chose v3 instead? They appear to be the same price for the 500mL I'd be ordering.
Is this just for those who don't have or want a proper storage procedure like I describe above?
with this stuff, should we still be storing it in the freezer, or does the AA help in this regard?
