Hey everyone, I been vaping for a while and never thought about this. With regulations and stuff being a hot topic now, I have beginning to think that maybe perhaps I should be stocking up. I've ordered a bunch of hardware/wire/cotton/batteries etc., but have yet to stock up on base nicotine or eliquids. I know that some people store their nicotine or pg/vg stuff in fridgerators and ive heard of people putting them in freezers but thats about it. Is there an expiration date on unflavored nicotine vase, whether it be PG or VG (does it even differ?) or does it not even have one? I've noticed some of my juices turn a darker yellowish color if I leave it out for long, and notice some real real old pre-mixed juices taste skunky after a long time, but what about just unflavored nicotine base? Would like to figure this out because I want to make a big order soon, but there would be no point if I was unable to vape it all before it goes bad.
