    Good product, slow shipping

    I understand supply chains and shipping is tough for everyone right now but from ordering to receiving it, it took around 4 weeks. Really slow. Product is great as with all blender bottle products.

    Cool design, mouth piece doesn’t lock down though

    It’s nice to have options to connect preworkout or protein powder on the go, but the lid for the mouth piece doesn’t click in. It didn’t have any damage or anything, so I don’t know why there’s an issue. This may be just a problem with mine; the bottle is great otherwise and handy, but it’s hard to shake if the top won’t close

    Hi AP,

    Ocean blue is so pretty!

    I have so many of these pro-stacks. Love the ocean blue color. I had difficulty closing the drink spout, a quick email to customer service got it all figured out!

    Common Questions

    How many jars does the ProStak shaker bottle with storage come with?

    The ProStak comes with two attachable jars. For additional jars, see the ProStak Expansion Pak. When you first receive your new ProStak, the second jar is in the shaker.

    What can I put in the ProStak attachable jars?

    The 100cc jar includes a pill tray within the lid—making it easy to carry pills. The jars are perfect for carrying pre-workout, protein, BCAAs, or any other supplement powder. Looking to carry a snack? The 150cc jar carrying small portions with ease.

    What is the SpoutGuard™ on the ProStak protein shaker?

    The SpoutGuard™ protects your drinking spout from dirty gym fingers. You don't know where everyone elses' hands have been when you touch those weights.

    Where is the pill tray?

    The pill tray is inside the 150cc staking container that is attached to the bottom of your bottle.

    What if I am having difficulty opening/separating the containers?  

    One suggestion would be to place another jar on top of the stubborn lid, grab the bottom jar by the base (not the lid), and slowly twist the top jar counter-clockwise until it catches on the Twist n' Lock ridge of the stuck lid, setting it free. We've also found that if gripping the lid too tightly, it won't loosen well. A loose grip on the lid will help it open with ease.
