Yes, TFA is part of TPA. They seem very pro with their details, recipes, and all.
They used to sell Tobbacco Absolute and Tobacco Extract, but seem to have stopped these, made from REAL tobacco. Any one know why? It was really a base ideal.
Their other products, under "Professional Flavours" in the TFA section, are really quite good, IMO, and you don't need too much, in between 5-15%.
But if you order directly from them, snail mail is an understatement! I'm in France and it took about 3 weeks, from Italy!
