Mt Baker, which sells mostly TFA flavoring, says they use 15% to 40% of a given flavoring to create e-juice. (They're talking about single-flavor e-juice, not mixed recipes.) This is way higher than the suggested starting points on the three different starting-point lists for TFA flavorings I've looked at. Does MtB dilute their TFA flavorings? (If it's at all relevant, they sell 15ml of TFA flavoring for $3.) Anyone have a clue how they come up with such high percentages of flavoring?
Nope. Mt baker uses and sells Flavor West.
