I'm new to all this I have been buying pre mixed salt nic with 28mg and just adding flavoring I realize I'm lowering the nic level especially bc I use so many different flavors in one dessert recipe. Anyway, I purchased a 50ml bottle of 250mg 50p/50v salt nic base and wanted to know how much I can/should add to give the 30ml ones I made to make the nicotine stronger at least 30mg nic content
