Okay I got the Throat Hit Plus from The Vapor Pro in the mail today. Here's my take on it: First of all, I used VaporRenu juice in butterscotch flavor, it is 100% PG, 24 mg nic, aggressive TH (but there is no TH and no vapor, either). I put 2 mL of that juice in a small dropper bottle and then added 4% (the website recommends adding 1-4% of Throat Hit Plus), which amounted to 0.08 mL. I placed about 15 drops of this concoction into a clean cartomizer. I then placed 15 drops of the butterscotch juice without the Throat Hit Plus into another clean cartomizer. I put each cartomizer onto a fully charged KR808-D1 battery and vaped from each of them. The result?? No difference AT ALL. I had to look at the cartos to see which one I had marked "TH" to tell which one I was vaping, absolutely no difference whatsoever.
I feel a little woozy from all the nic I've vaped in the past 30 minutes, but I wanted to be sure there was no difference, for the sake of research! LOL
So my search for good TH continues....and my frustration mounts! Live and learn, huh.
