I have 250 ml of nicotine that is 6 yr old. Is it still good?

I have bought nicotine from wizards lab, 6 years ago. It has all ways been in the dark , in a coolish place. Is it still OK? It is in a VG base. Does any one know of any chemical degradation of such? I am going to have to start mixing up my own. Hi! all my friends that I have not seen for a while! And Hi new friends.
