Glycerol question

[Helfrd0771]

I went to cvs last night and found a bottle of glycerin for 5$ I didn't buy it. After I left cvs I searched it here. It seems to be the stuff people are using. However, no where on the bottle did it say it was veggie based. Also there was a warning about ingestion.

So the question is how do I know it's vg and not animal fat based?

Also when I mix it into my existing e liquid do I need to do anything like shake it to get out fully mixed?

Thank you in advance for your help.

Sorry no one's replied to this post. CVS's Glycerin will be marked USP which relates to Vegetable Based.
Yes, VG mixed with flavor or another juice needs to be shaken daily for a few days to incorporate it. In fact, all e-juice should probably be shaken well before refilling your attys.
