G FUEL Just Entered the Creatine Game — And Final Boss Sour Got One of the First Flavors

G FUEL is officially expanding beyond energy — and Final Boss Sour is helping introduce the brand's new creatine lineup.

The new G FUEL x Final Boss Sour Strawberry Creatine combines a seriously sour strawberry flavor with 5g of creatine monohydrate in every scoop. Each tub contains 40 servings, zero sugar and no caffeine, making this a completely different product from the caffeinated formulas G FUEL is best known for.

G FUEL Creatine Is Officially Here

G FUEL describes the Final Boss flavor as starting with juicy strawberry sweetness before hitting with a sharp, puckering sour finish — fitting perfectly with Final Boss Sour's over-the-top candy identity.

It's one of three flavors launching in G FUEL's new creatine range alongside Push Pop Blue Raspberry and Push Pop Cherry Watermelon, with all three delivering the same 5g creatine monohydrate formula.

This also isn't the first time the two brands have worked together. G FUEL previously partnered with Final Boss Sour on its Level 3 Sour Shirley Temple energy formula and candy collaboration, making Sour Strawberry Creatine another major extension of the partnership.

G FUEL currently lists Sour Strawberry Creatine at $34.99 for 40 servings, with discounted subscription pricing also available.

Between G FUEL entering the daily creatine category and Final Boss Sour bringing the flavor insanity, this might be one of the more unexpected supplement collaborations of 2026.
