Raising the Bar. Again.

Fully Independent Jars

Keep powders and pills in place - with or without the bottle. The ProStak’s unique interlocking jars have individual lids, making it possible to carry pre- and post-workout supplements, meal replacements, and snacks, even without the bottle.

100% Leak Proof

Drink your shake, don’t wear it. The ProStak’s screw-on lid and SureSeal™ flip cap keep your shake where it belongs. With a snug twist of the lid and the assuring “snap” of the flip cap, you’re ready for some serious shaking.

Patented BlenderBall® Wire Whisk

Try as they might, mesh grates and plastic gimmicks inside other shaker cups simply can’t compete. The BlenderBall wire whisk delivers lump-free protein, nutrition, and meal replacement shakes, even blending flavorful additions such as peanut butter, yogurt, and oat flour.
