Nic It Up is a range of nicotine booster shots designed to be added to shortfill and 0mg eliquids, they should not be used on their own. The quality nicotine used means that these shots will not reduce flavour or cloud production from your eliquids and they're very kind on coils.
A range of VG percentages makes these nic shots compatible with most eliquid blends, higher VG shots are best suited for use with high VG eliquids, each shot features an 18mg nicotine concentration.
When added to shortfills, these shots will increase their overall nicotine content. For example, adding an 18mg 10ml shot to 50ml of 0mg eliquid will create 60ml of 3mg eliquid, whereas adding two shots to 100ml of eliquid will create 120ml of 3mg eliquid.
