Back when I first started my vape journey, one of my ADVs was Blue Jitsu from Vape Dudes. Welp, they are no longer around, so here is my not-a-clone-just-a-tribute. (they likely copied it from elsewhere anyway) Sweetener optional, although this really doesn't need it (and I tend towards mid-sweet recipes)
I've tried to formulate this so that no one flavor stands out, just one yummy blend. The apple starts out strong, but mellows nicely after a couple of weeks. I've tried many different flavor combos (and will continue because... it's what I do :), but (so far) I always come back to this lineup.
For a more tropical sensation, I replace the apple with 1% Guanabana.
