In order to really see a difference try to buy some vg and add it to a 70/30 blend. I had to do this with store bought since it was the reason why I had to stop vaping a few years ago. I'm now into DIY and the one store bought that I will keep buying I add VG to that one.
Anytime I get to 70% PG I go into itching and feels like I have creepy crawlies all over me. It's the pg in my case. My doctor was quick to address it back in 2015. I enjoy the DIY now since I never itch anymore.
