If you are a seasoned vaper, chances are that you have tried an RY4 e-liquid blend. RY4 is one of the oldest and most popular e-juice flavors in the history of the vaping industry. Atomic Dog Vapor describes it as “one of the world’s most desired flavors.” RY4 was one of the e-liquid flavors released by the company which started the e-cig revolution, Ruyan Group Ltd., In 2014.

Atomic Dog Vapor’s Code: RY4 is a classic e-liquid. It contains the same three ingredients as the original: tobacco, caramel, and vanilla. Although there are many different RY4 blends on the market from different e-liquid makers, this one from Atomic Dog Vapor is exceptional. If you love tobacco flavor, then you will love this one. It goes without saying that Code: RY4 is an all day vape.

Code: RY4 by Atomic Dog Vapor has a well-balanced taste. You will pick up the flavor of all three ingredients from the moment you take a hit off this e-liquid. What’s more, this RY4 blend does not have any harsh taste like some tobacco e-liquids that you will find on the market. The thing that makes the RY4 e-juice stand out is that its taste is somewhere between that of a tobacco and dessert e-liquid. The sweet and creamy flavor of caramel and vanilla juxtaposes the earthy tobacco flavor nicely. Code: RY4 captures the essence of the RY4 blend. It is not too sweet, and it doesn’t have any weird aftertaste. If you are looking for a tobacco e-juice, but you want something yummy, try this one.

Like other e-liquids from Atomic Dog Vapor, Code: RY4 has a vegetable glycerin (VG) and propylene glycol (PG) ratio of 70/30. It is suitable for both dripping and vaping from a sub ohm tank. This e-liquid is not a coil killer. The vapor production of Code: RY4 is consistent with its MAX VG ratio. You will get thick plumes of vapor from each hit. If you are a cloud chaser, you will not have any complaints about this e-juice.

Atomic Dog Vapor produces Code: RY4 with varying nicotine strength levels so that all vapers can enjoy the same great flavor. It is available with either 0mg, 3mg, 6mg, 12mg, or 24mg of nicotine. For most vapers, 3mg to 6mg would suffice to deliver a satisfactory throat hit. However, if you are a heavy smoker, then you will need higher nicotine levels. This e-liquid is made with superior grade nicotine so you will not get any throat irritation from vaping it.

Code: RY4 comes with the usual packaging design that Atomic Dog Vapor uses for all its e-liquids. The e-juice is packed in an opaque blue bottle with a nice silver top cap.
