LEAN WHEY® MONSTER COOKIE

DISCOVER THE FLAVOR ADVENTURE

Lean Whey’s daring Monster Cookie flavor set out from SuppChef’s workshop on a mysterious quest. It was said that in the shadowy depths of the forest lay a rare golden oat cluster that could amplify flavor to legendary heights. Monster Cookie, eager to become the most powerful flavor in all the land, assembled its bravest friends: Chocolate, with a rich, fearless spirit, and Pumpkin Spice, who carried warmth and courage. Together, they ventured into the mist, but lurking among the twisted trees were spooky fiends—the Sour Goblin, who tried to turn everything bitter; the Sticky Marshmallow Wraith, whose gooey webs could trap even the swiftest; and the Crunching Crumbler, a menacing specter made of shattered cookie crumbs. Through teamwork and courage, the flavors evaded each fiend, finally claiming the golden oat cluster. When they returned to the workshop, Monster Cookie had become richer and more irresistible than ever, filled with a delightful boost of magic for anyone who dared to try it!

EXPLORE THE TASTE

The Monster Cookie flavor of Lean Whey combines a classic, cookie-inspired profile with rich, creamy undertones. It has a smooth, slightly sweet vanilla base with bursts of cookie inclusions that create a satisfying, almost indulgent experience. You’ll notice hints of chocolate chips or cookie crumbles, which add texture and a subtle cocoa finish, evoking the flavor of freshly baked cookies. The taste is comforting and familiar, making it an ideal choice for anyone who loves the flavors of homemade cookies in a protein shake form.

Monster cookie is excellent especially if you use it in an ninja creami machine

Monster cookie is excellent especially if you use it in an ninja creami machine. They really know how to make protein powder special. All the little additives add up to a mouth watering dessert shake or ice cream.

Great for Ninja creame ice-cream.

For a while, I have been purchasing protein powder from MuscleSport. This is my first time trying the monster cookie flavor, and it's my new favorite flavor for making ice cream

Great flavor. Love mixing it with a banana blueberry and milk. Flavors hold true to the title.
