Review of Polar Blast Flavor-FA:

I know this stuff is just 7% Koolada and 3% Menthyl Lactate, but all I'm getting from it is clean, clear coldness. My best guess is that the menthyl lactate is used in low enough concentration that it doesn't impart a minty taste, but somehow paves the way for Koolada to not have that bitter, chemically off note associated with it. 

Great stuff.
