This is the mixture I like best... using TFA flavorings and my Nicotine is 100mg/ml (10%) in VG.
TFA Milk Chocolate - 10%
TFA Raspberry (ripe) - 10%
TFA DX Bavarian Cream - 3.3%
To make a 30ml bottle of 50/50 PG/VG, at 6mg Nicotine level... mix the following:
1.8ml Nicotine (100ml/mg in VG)
8.1ml PG
13.2ml VG
3.0ml Milk Chocolate
3.0ml Raspberry
1.0ml Bavarian Cream
Adjust the Bavarian Cream and Raspberry to taste... I like a bit more Raspberry for the tart berry taste, but for creamier flavor, use 2ml each Raspberry and Bavarian Cream. You can also use Dark Chocolate, but if you do, I'd use a little Vanilla Custard or Marshmallow to add a little sweetness to the mix.
