Hello,
I have tried the chocolate carmel, & vanilla flavors in the ready to drink cans. They do carry a powder type as well, but haven't tried it. I prefer the ready to drink versions, it's easier to take with you to work for lunch or afternoon snack. I also tried a non-carbonated energy drink from the same company that tastes great. Tea-Berry Blast. I drink them before working out. It has only 1 carb & 0 sugar and lots of B Vitamin.
Hope this helps.
Cindy
