Flavourshots (or Flavorshots) are complex flavourings. Well-known e-liquid producers occasionally release a flavourshot version of their creations. Flavourshots are usually sold as a Propylene Glycol (PG) solution together with a small bottle of Vegetable Glycerin (VG). First you need to add the VG to the flavouring. This will result in a Shortfill e-liquid. You then need to add more base or a nicotine booster to obtain the desired nicotine strength and PG/VG ratio. You can thus simply follow the instructions in our Shortfill (Shake and Vape) and Nicotine Calculator and Shortfill (Shake and Vape) and PG/VG Calculator.
