What’s Up? by Super Flavor is a sweet donut filled with vanilla cream. The PG/VG ratio is 30%PG/70%VG. This shortfill e-liquid is produced in Italy and comes in 60ml bottles filled up to 50ml so you can add 10ml base.
You need to add 10ml of base. The nicotine level and PG/VG composition of the base will contribute to the end result. Here are some examples:
50ml Shortfill e-liquid + 10ml base 0mg/ml nicotine = 60ml e-liquid with 0mg/ml nicotine.
Shake and Vape (50ml) e-liquid + 10ml base 9mg/ml nicotine = 60ml e-liquid with 1.5mg/ml nicotine.
S&V with 50ml e-liquid + 10ml base 18mg/ml nicotine = 60ml e-liquid with 3mg/ml nicotine.
