Nicotine booster shots are specifically designed for use with shortfill e-liquids, in order to literally ‘boost’ the nicotine content and total volume of your e-liquid.
These nicotine shots are clear and flavourless liquids, and are available as either standard freebase nicotine shots or nicotine salt shots. The first of those, freebase, is the purest form of nicotine, and the standard one found in e-liquids in the UK.
Nicotine salt, meanwhile, doesn’t actually contain any ‘salt’ or crystals – it is simply freebase nicotine combined with benzoic acid. This makes for a smoother and less harsh vaping experience than freebase, thereby enabling you to more easily vape higher nicotine strengths.
The other thing you’ll need to be sure of, is how to get your mixing right. Adding a 10ml 18mg nicotine shot booster to a 50ml shortfill, for instance, will give you 60ml of 3mg e-liquid. For a more comprehensive guide to the possibilities, simply consult our shortfill mixing chart!
