Remove both caps from bottles then squeeze the full 10ml of nicotine shot into the bigger bottle then replace the cap.
Time to shake in that nicotine. Start shaking the bottle vigorously for a minimum of 30 seconds to ensure all the nicotine has been effectively mixed with the 0mg E-Liquid. This step is important to get a smooth hit.
Add your mixed 3mg E Liquid into your device and vape away! No steeping is neccessary.
