Lol. I do too. I have a hard time comprehending how nicotine frozen at minus 4 degrees could lose potency or go bad.
Bought nic from 3 vendors. Only one smells "flavorless"

It's an organic molecule that oxidizes so a loss in potency is unavoidable. But in a freezer I think it's nothing more than a loss of single digit % after years. I'm still interested in seeing samples tested that are years old tho. It lasts longer in PG tho, and that has a freezing point of around -75, so it's not gonna be frozen in there. I think w/ VG, it's a quicker medium for oxidation to occur. If you ever notice when you shake a high VG solution, there's tons of tiny air bubbles in it, which seems to support that theory.
Expired distilled dihydrogen monoxide? That s&@t will kill you! Rebel.
Nic, even very pure nic, can have a smell, and that smell/taste can vary. We are not sure where the smell comes from, since ultra-pure nic (like Alchem which does a distillation after the final extraction) has virtually no smell/taste, but it is my belief that it comes from trace non-nicotine alkaloids that come along to a small extent in the extraction process. I have seen excellent analysis results on nics that have a popcorn, peanut to sharp acrid smell. I actually like those to vape unflavored.
The three companies you mention have good reputations for putting out quality nic. WL especially tends to put out a very consistent product. WL Ice, no longer available it seems, was more odorless and tasteless than their regular nic, but even their regular is very low smell/taste. MFS recently increased their purity and seem to be putting out ultra-pure nic these days. Was not always the case, but then I am considering nic from 2009. MUCH has changed in purity now, across the board. I think trace oxides also have a particular taste, and may be responsible for the tobacco notes that seem to grow in with an aged nic.
I would not worry about argon gas. If they are not shipping in glass, I think Ar is moot, since O2 can slowly get through a plastic container. Once it is opened, the argon is gone, anyway. Freezer store in glass, well sealed, to get the most time out of the nic.

You sir, were correct. I whipped up some 6mg butterscotch with the MFS and it does not taste like it smells.
There was absolutely a difference when I first opened them. I'm not going to speculate as to why, as all of them smell the same now. The strongest smelling one does not seem to add any undesired flavor to the juice. I will make up some 12mg this weekend to test, but I think the results will be the same.
It's nice to know that smell and taste doesn't equate to purity. Doesn't make it easier to vape tho.
Okay guys. I used the test kit on all 3 nics. Here are the results:
MFS 100mg - Tested at 113.5mg
WL 100mg - Tested at 103.8mg
NN 100mg - Tested at 90.8mg - I assumed that we screwed up, so we re-tested @ 92.4mg
We were going to re-test the MFS, but it does smell stronger than the others as I previously mentioned, so I believe that the test is accurate.
If I mix the NN and MFS together, that would be 102.55mg. I might do this...

We did... I might put the 3 bottles in a zip lock bag and set it in warm water for a bit, shake, and then restest all 3. If I have time.
My buddy and I also made up some more juice. He made 10ml / 18mg of Pineapple, I made 10ml / 12mg Watermelon. Both (TFA)came out great at 15% 65/35 PG/VG. We did them in 10ml graduated cylinders. I highly recommend this method. Simply make notes on the recipie chart for the total volume after adding each ingredient. Nic to 1.2ml line, PG to 6.5ml line, VG to 8.8ml line, flavoring to 10ml line, done. Easy as pie. Easier, actually. no waiting for the oven to warm up.

Sounds a lot easier than washing syringes. Were you using a 10ml cylinder? Is it graduated in .1ml increments? I'm going to have to try that. Sounds like your making some good stuff right off the bat. Congrats!

Just in case anyone else is a juice miser.
I transfer 100 mg on clean surface.
I sop up spills w/ clean cotton gauze.
Put cotton in syringe and squeeze extract the juice; I vape the recovered juice first.
Sometimes, I extract juice from wicks w/ syringe.
I syringe mix and don't waste a drop; have dedicated syringes for VG, PG and nic. So far, syringe mixing is close enough for me.
Aqua clone has driven me a little nuts because I have spilled too much juice fiddling w/ that booger. I don't loose any juice w/ Genny.
I know it takes a while for VG and PG to become homogeneous; takes a fair amount of shakes to rid the striations. VG and nic may mix much easier. Hopefully I shook the 1L enough before 30 ml transfers.

I transfer my nic to glass bottles. then I put the plastic bottles upside down on a funnel that is in a smaller glass bottle and let it sit a while. last time I did this I got about 20ml extra liquid from 2 250ml bottles

After draining 100 mg bottle I rinse w/ PG then vape the PG.
I quit using funnels and hit the mark...most of the time
No need to treat like gold now but who knows down the road.

oh, that's a good idea. ok, I'm cheap (or poor)
Got my 250ml nic in glass bottle from MFS today...either my nose is totally stopped up or it has little to no smell that I can detect.
This is getting bad. I have a liter (well one 60ml bottle shy) of 100mg/ml Nic in the freezer and with all this craziness going on (legislative), I'm thinking I might need to order more.
