I could list off tons of amazing flavors, but this one is my favorite.
Go on MTBakerVapor and search "Fruity Hoops" and select "Max VG" and then pick your nic level (if you are putting this in an RDA do less than 10 or the nic level will overpower the flavor and it will taste horrible). Keep in mind the flavor doesn't actually taste like ceral, it has a fruity combination taste.
Always do max VG because all pg does is dehydrate the shit out of you.
I highly recommend you check out Dr. Crimmy!
Sadly you need a credit or debit card to purchase from there, but it's the most high quality juice I've ever had.
