Hello, i have been vaping for about three years because of having a son and quitting cigs because of it. i found a great deal on unflavored eliquid and menthol crystals. im getting a 250 ml bottle of 24mg 50/50 pg/vg unflavored liquid and a .25 bag of menthol crystals but considering getting a second .25 ounce bag or just get a one ounce as the retailer only has .25 or whole ounce measurements (also has 4 as well as 16 ounce etc). what my GOAL is, is to just add the crystals to the main bottle so i have a 250 ml bottle of menthol liquid and have about a 4 or 5 month supply ready to go. ive seen all the other threads (fill a bottle halfway with crystals, pour in liquid let dissolve and add about a drop per ml etc). i used to smoke Newports if that gives you an idea of the menthol strength i like although i did like Kools too. what would be an effective way to get the desired level of menthol flavor using what i am getting. i decided to go with a premixed liquid for simplicity as well as safety so i didnt have various liquids and nic solution to have to keep track of or that my son might accidentally get into.
