I've bought everything I need to DIY and I'm trying to figure out how much PG is in my nicotine. I have wizard labs 100mg per ml PG base nicotine . I've got some lorann flavorings that are PG based also. I've got my glycerin but I don't just want to start mixing with out knowing the pg ratio of my nicotine. Ideally I want a 40pg/60vg base. Anyone know how I figure this?
