I bought two of the original tubs. Not sure if/how the formula changed. Curious?
Regardless, I like it. The taste is hit or miss like said above. I wouldn't say it's good or bad, kind of like apple cider.
The effects are very good. I would suggest drinking one serving at a time. The effects are pretty acute- personally I'd rather space out the effects by taking two servings over two different drinks separated by 2 hours or so- if I was using for productivity.
