I bought this life brand glycerine usp at shoppers drug mart just a while ago. Based on what i read on this forum, they safe its safe but that was years ago. I just want to confirm if it is really really safe. What i'm gonna do is mix it with my 18 mg e-juice to lessen the nicotine content. Any ideas about the dilution? I have a 15ml bottle. Thanks for the answers!
Is glycerine usp from shoppers safe?

Hi, if the bottle is years old I might be worried, does it have an expiration date on it? If the bottle is still sealed and crystal clear in color it might be OK to use, but maybe you should use that bottle for skin lotion and go get a fresh one to use for juice making. Better Safe than sorry! 
But a fresh bottle with USP just means its Pharmacy grade and OK for purity, so use away.

As far as dilution goes, what is the nic level you want your final mix to be?

If it is more than a couple of years old, especially if doesnt have the factory seal still intact, throw it away...well or at least dont use it to vape.
USP is the highest purity of VG you are going to find.

I have used USP grade for a year and I usually dilute my juices now 2:1 or 2 (10ml)parts eliquid to 1 (5ml)part vg. That should get you down to 12 nic. 1:1 (10ml/10ml)will give you 9 Nic. Hope this helps.
I cut some juices to 6 to drip and most from 12 to 9 to vape. Slowly trying for 0 but happy at 9 with as much as I vape.

I've been using Shoppers USP glycerine for two years now. All I can say is I think USP grade is the best we can get these days and I'm still alive and well
