Hello, newer poster here so i hope im in the correct fourm. I diy Menthol, menthol cyrstals, PGA, as the flavor base 10%, , distilled H2o 10%, 100ml nicotine in VG, i adjust % per week, and VG the rest. I use a 2 to 1 mixture for the menthol crystals and PGA, 2 parts PGA to 1 part MC. For the life of me i can not get the menthol cryatals to stay mixed more than one day, unless im out in the heat all day, if i reduce the amout of flavor i can get them stay mixed but then my juice does not taste good or mentholy. Is there a step or process im not doing? I have researched everywhere, and there is not alot of info i can find. Any help would be soooo greatly appericated, thank you
