We make our liquids at a standard 3mg strength. However should you wish a higher strength we can add extra nicotine to the bottle to increase the strength.
If you require this select the appropriate strength from the drop down menu on the item page.
Please note that as this is adding nicotine to a product that has already been mixed and steeped, it may change the flavour a little/impart a slightly chemical taste while the flavours bond to the nicotine. Selecting a higher nicotine strength is at your own risk as we can not accept responsibility or returns if you are unhappy with a product that has had extra nicotine added.
