So What Is RY4 E Liquid Anyway?
RY4 is one of the original tobacco blends. It combines three core flavors:
- Tobacco (mild, not ashy or bitter)
- Caramel
- Vanilla
Simple, right? But the best RY4 juices know how to balance these flavors so nothing overpowers the rest.
Fun Fact: RY4 got its name from “Ruyan 4,” the fourth version of the original recipe created by Janty and Dekang chemists. The rest is history — and RY4’s been a staple ever since.
Wrapping Up…
RY4 might be old-school, but the best ones still hold up today. Whether you’re after a smooth all-day vape or something different from fruit or ice, a solid RY4 like ours brings flavor, throat hit, and satisfaction.

What’s the difference between RY4 and regular tobacco e-liquids?
RY4 is a blend of tobacco, caramel, and vanilla. Regular tobacco juices don’t have those sweet dessert-style notes.

Go for 10mg or 20mg Nic Salt — they’re smooth, even at higher strengths, and perfect for MTL vapes.
Is RY4 good for quitting smoking?
Yep — the tobacco base gives it familiarity, while the caramel/vanilla helps it taste way better than a cig.

Depends on how much you vape. 10ml is grab-and-go. QuickMix is fast and affordable. Longfill is best value long-term.
