Hey guys.
Maybe this is already answered elsewhere, but I can't find it.
I have run across the terms TPA and TFA and I have no idea what they stand for.
It seems it is being used in connection with certain types of flavors and since I am going to start DIYing I want to make sure I understand all this.
Thanks.
