My max VG juice lost viscosity.

I just had some of my favorite juices go bad on me, I think. I moved 3 weeks ago and some of my juices were in 100+ degree heat for several hours. I went to use the juices and some had turned dark and even my high VG juices went runny. They smell OK but I'm wondering if they are OK. Does nicotine break down in heat? I'm vaping 12 mg juice. I'm thinking I should just throw them out but I hate to lose all that juice.

Are you saying it's thin after time or when you found it.
Vg thins when warm, which is why alot of folks heat their diy. Basically to thin it and speed the steeping process.
Darkness could be because it steeped/blended.
If it's still thin after returning to room temperature I wouldn't trust it at all.
But if it returns to the original thickness it may be ok.
The problem here is you don't know how hot it actually got, so it may be trash.
I'm sure others will chime in.

The juice was at room temperature when I looked at it and it was as thin as water. The juices are mostly high VG, around 80%. With the outdoor temps around 100 degrees the juice might have gotten as high as 120 degrees or so in the van and it would have been at that temp for 2 hours.

Vape some. If it still tastes ok, it probably is. I used to speed steep some of my stuff by putting the bottles in scalding hot water for a while. Hours sometimes, probably.

I found three year old partial bottles of my then favorite liquids in an old laptop bag that had been in storage. They were fine and one actually tasted even better than it did when I thought it had finished steeping.
