I keep all my 100mg VG Nic in the freezer in the big Brown & Blue glass bottles, have some that is 2ys old and is still great, there is also no proof as of yet that it will lose its strength and personally I don't think it will at all if any, there is nothing to make this scenario happen to this chemical that I can see this happening,,,nothing is going to eat the strength

so the test is ongoing for me.
madvapes is also running a test that is posted on there news letter and probably on there website as well. They have like 4 bottle, one in the freezer, one in the fridge, one on the window sill, and one in a cool dark place I believe, or something like this, they are posting the results weekly of the Nic test they take weekly until it runs out, so this is a good thing. I highly recommend you keep it right where ya got it but maybe got some fresh Nic and put the bottle in the freezer too so you always have some good clean fresh Nic. Oxygen and heat aren't the best things for Nic, it
thrives in cold and not letting oxygen get to it.
