PS, I’m over 73 years young and smoked 2+ packs a day from 1970 to 2017. My taste buds are shot and can’t taste most flavors. I mostly know I have a good mix when the people around me say 'That smells good, what is it?'
After April 2017, I have not bought any premixed Liquid, I figured I brew my own beer and infuse vodka to make spiced rum so I can mix some flavorings with PG, VG and Nic. I use 100 mg (10%) Nicotine for my nic in PG.
I prefer EJuiceCalculator and only started using e-Liquid Calculator in 2018 for DIYorD1E Twitch shows.
I label everything using GIMP 2.10.14 free ware ( https://www.gimp.org/ ) and Avery, Water Proof 5520 labels.
