I have TA from FlavourArt. Haven't tried it in anything yet, but I will.
I used a toothpick to smear a tiny amount in a bottle, then added about half a ml of PGA and swished it around as best as I could. Then I filled the bottle with roughly 5ml ethyl maltol (at around 10%) PG.
Haven't decided what to do with it first. Dilute to 5% and testvape, nah, would probably be too sweet, maybe 3%?
