Ive started doing the diy juice deal about 4 weeks ago. Ive been speed steeping them in the crock pot for 4 hours, shaking them vigorously every hour. Im just trying to figure out when to put the nicotine in. Some people put them in the recipe as if they put it in before they steep them in the crock pot. Some people say that heating the nicotine up reduces the amount of nicotine you put in. When exactly should i put it in??
