It actually tells you on the bottle the amount of each of VG, PG and nic you need, just add the PG & VG values together (normally you'd adjust the PG or VG depending on which your nic is in).I have ordered a Boss Shot from Flavour Boss. Does the concentrate come premixed in a bottle? And do you just add your PG/VG Nic.
I ordered the Lemon tart 500ml which says 15.5%. So do I presume that I add 84.5% = 422.5ml of my 70/30 nic mix?
