Hello all been lurking for a little while in this section but am getting kinda tired of buying pre-made stuff for my dad and was looking into possibly making it for him myself. What I was wondering though is I found a website that sells 6mg liter bottles of nicotine and it said it is a 50/50 PG/VG mix, what I need to know is if I were to purchase this liquid would the only other thing I need be flavors or is there something else that I would need to purchase. I have been reading up on DIY stuff and while I understand the mixing aspect I just need to know would I still need to buy a PG or VG base or is it already there in the nicotine liquid I would be buying?
