TW liquids have Glycerol. Is that VG? Also, do Dekang's liquids have VG?

I made my first DIY liquid with just pg (english toffee) and it tastes fine, throat hit is fine, but the vapor is WEAK. A few drops of VG helped, but I was wondering how the manufactured liquids I've tried get so much vapor with what I assumed was only pg. Now I'm not so sure.

Glycerol is Glycerin is Glycerine. All are VG - though VG is specifically Vegetable Glycerin, made from vegetable (typically palm or coconut oils I guess). Non-vegetable Glycerin is often made synthetically or from animal fats.

Most people consider them all to be equal, though I prefer 100% Vegetable Glycerin.

It would not surprise me if many/most commercial e-juices contain glycerin to get the vapor production and a desired viscosity.
