Some of your competitors have noted that, while they may sell the flavors, they may contain substances (natural oils or sugars, especially) that may not be suitable for inhalation. Some examples:
blueberry
Amaretto
coffee
peanut butter
Since the flavoring is potentially deadly part of vaping, and with diacetyl being the hot topic it is on the forums, I'm curious what testing you've done on the materials from your own supplier.
