rex

I'm trying to clone Rex by Opus Elixer, and I'm looking for clues of what they use to sweeten their juice. It's a simple kiwi and strawberry, but it's intensely sweetened. After dripping Rex, and waiting a few hours, the cotton will oxidize into a pinkish, reddish, brownish color. Could this be...

One of the most popular juices in NYC. It's beautiful. It's also really strong. Anybody has any idea how to clone it? I was thinking it's gotta be some mixture of TFA Double Kiwi TFA Strawberry Ripe TFA Strawberry TFA Gummy Candy and a ton of sweetner, which I'm not too familiar on which to use.
