I haven't purchased any DIY supplies since last March and likely won't purchase anything until at least March when a few flavoring will need replenishing. By March it will be 2 years since I've purchased any PG or VG so I'll likely purchase some new even though I still won't have run out of either.
So what would you estimate shelf life of PG Nic base ? 2 years ?
I got some coming in so i should be at about 18months supply now @4ml/day, but wanna stock up in case things get ugly here in europe ! Just worried about nic base for now, pure VG/PG is easy to get
