I am also a huge lover of titan menthol! My favourite by far.
I like my mixes to be 50/50 PG/VG and the titan is a different ratio.
I have tried on many occasions to mix a titan menthol vape-a-like, and sadly have never got anywhere close!
I've tried mixing DV menthol with mint, spearmint, peppermint, Ice, (cant get hold of nannamint so haven't tried that one yet)
I have even tried the Newport menthol... and Nope!
I have some 36mg titan menthol and have added a few drops of VG but it cuts the taste and it's horrible!
So I can totally sympathize with you
So unless you're willing to vape the 11mg... I really don't think there's a lot else that you can do.
