Time limit on pre-workout drink mixes?

[twarrior]

I just ordered some jack3d and was thinking about mixing some to take to work with me. I car pool so I'd like to drink it when I'm on the way home so it will be in force when I get to the gym. Are the time limits for consumption on the ingredients after they're mixed with H2O??

I don't know about jack3d, but I usually take my Pre WO supplements at the max 30 minutes before I start. I think you will be fine though.
