Let me show u how I use them:
I fit my Herbalife Beverage mix (snack), Prepare (pre-workout), and rebuild (post workout) shake all in this nifty and easy to use shaker attachment. It's made to put your tablets in for lunch or for day, but I have a tablet box I use.
Here is the bev mix and prepare in one container.
So in the end these r my powders for the day- shake for lunch, snack, pre workout and post workout. A lot packed into one thingy!
They screw onto each other also and make it easy to take this one item out the door for your day! U can switch the powders and always be ready for your day!
