If i where going to buy menthol i would ,and do use this one. Its from Good Prophets, the GP USA liquid Minthol flavor. Right now a 10ml bottle is 2.99. Its an in house blend and i personally find it to be one of the best that i have tried. If you would like to pm me i also would offer you a small bottle of what i use all day that i personally make for myself but its not for sale nor would i accept money for it.
