I think a lot of people here (as in most/all/everyone) won't take the idea seriously that your vape
shop spins all it's VG in a centrifuge and throws out all the heavy stuff, just skimming the light stuff off the top. Assuming VG even separates, which it probably doesn't. As I understand it, there is only one VG molecule. It is not a collection of dissimilar molecules that might separate.
You are also the only person I've ever heard here even suggesting that nicotine needs to be "steeped" into VG. The rest of the world steeps the flavors into the base. The fact that your
shop claims to do that is surely raising a lot of eyebrows here.
I am very impressed with their marketing though... wasn't it Einstein who suggested that great marketing is indistinguishable from magic, or did I get that all mixed up?
