What *IS* RY4?

[Baldr]

When I started vaping, they suggested RY4 when I said I wanted a tobacco flavor. They lied. Very sweet, with no tobacco flavor that I could notice.

For obvious reasons, I haven't tried it again.

Ive tried 2 ry4's so far , vaperite 3ml sample and i liked it (kinda caramelly tobaccoy) , so i ordered a diy ry4 flavor from bluemist and it is totally different and sucks to me (kinda like mentholy dirty sock flavor) .
