That was a great description of the product. We might have to use that in our advertising going forward.Nice, always good to know that other people here have used the same thing with success.
Just got the kit today, woot! Mixed up 60vg/40pg 10ml of 18mg Blueberry, vaping it as I write this. I always pictured DIY as something complicated, but it's really just a little math and a lot of funI don't see myself buying much pre-made juice going forward, now that I've seen DIY firsthand.
Super cool, nice work! The kit is absolutely packed, like clown car full of DIY awesomeness.
The pamphlet in the box recommends freezing the liquid nicotine, which comes in an amber plastic bottle. Should I first put it in a dark glass bottle (which sounds like the way to go, based on other posts in this thread), or is it OK to freeze in the amber plastic?
On that note, I also see notes about making sure the bottle is topped off to avoid oxidation- is it OK to freeze it after each use, even if the bottle ends up with more and more empty space as I go along?
Final question: is it possible to get a full ingredient lists for the flavors? I'm trying to avoid artificial sweeteners like aspartame, but they just list 'natural and artificial flavors'.

For your first question, you will be fine freezing the nic in the PET bottle it came in if you are going to use it up relatively quick (over the next 6 months or so).
Again, you will be fine to refreeze in the bottle it came in after each use, but if you want the least amount of oxidation you will want to split the bottle up into a couple different bottles. That way as you open and use a bottle you are not exposing the entire amount of solution to air, only that one bottle.
For your last question, we are not the manufacturer of the concentrated flavors that we sell. We simply rebottle the flavors. The best source for information on flavors is straight from the manufacturer (TFA, Flavor West, Capella, etc.). If you have a question about a specific flavor or two then I would be more than willing to try and get an answer for you, but if we took every question like that we would get inundated with those questions.
