diluting vendor juices

[mayday123]

Hello again, most vendors either sell 6mg or 12mg juices, i am one of those that like a 8-10 mg juice, how can i make vendor juices to my liking, is there a way? can i buy the flavor i want at the mg i want, and then buy 0 mg of the same flavor, that way i wont dilute flavor, im making it to complicated, sorry? any help would be appreciated

Buy a 6ml and mix it with the 12mg to obtain a 9mg finished product, just use equal ml
