So I bought a bottle of 12mg 70/30 unflavored nic, which is where I'd like to start playing around at. I know flavor and sweetener will dilute it down some, I'm fine with that. Now the question I have, because safety is a huge concern, does the blend I bought need to be diluted down or is it safe to just start mixing flavors with? Is that 12mg per ml or is it like buying a pre mixed bottle from the store? I got it from vapordynamix.com from their diy section. (I apologize I'm on my phone and can't post the link) thank you for your time
