I currently mix my own fruit stripe E-Liquid which is one of 2 all day vapes I have. The other is HS Premium Menthol. I have been thinking about making my own menthol for a long time now and I have heard that all I have to do is dissolve some crystals into my 80PG/20VG 12mg mix and Bob's your uncle. I have also heard that some menthols use sweetener. In essence what I am looking to do is replicate HS Premium Menthol, so any advice you can offer would be great appreciated.
