Well, drinking this was a big fat mistake.
The day drained me pretty bad, so I bought one of these to get change for the bus (mom pays senior, I pay day pass) I stuck it in the freezer when we got home, that was also a mistake.
Only the top froze, really. It tasted better than most energy drinks, kind of a lousy chocolate milk. When I was done, it felt like there was more in the can, so I rinsed it out in the sink. And was kind of horrified, there was a gelatinous substance at the bottom of the can, I'm guessing that's the protein bit.
I've never done amphetamines, but this thing has me way more hyped up than red bull. My typing speed is pretty good though.
