I am always a little leery about inhaling the mystery liquid from china.
The Totally Wicked boxed repackaging of e-liquid(*) has the advantage of displaying all the ingredients.
* it's exactly the same flavor list (plus lorann and decadent vapors) as Dekang so i assume it is it.

edit:
All that ???-pyrazine stuff is aroma apparently:
Pyrazine - Wikipedia, the free encyclopedia and used in traditional Chinese medicine... kind of make sense that they got the idea to use it actually
other ingredients are actually things like a dry alcoholic molecule and other stuff.. all seems pretty safe despite the weird names !
