Build like the champ, without the bloat.

CBUM Mass Gainer is engineered for lifters who want clean size, fast recovery, and sustained performance—without relying on sugar-loaded formulas that leave you sluggish.

Each serving delivers a massive 1070 calories, 53g of premium protein from fast-acting whey and slow-releasing casein, and 200g of complex carbohydrates from ingredients like oat flour, sweet potato starch, quinoa powder, and maltodextrin. This combination fuels intense workouts, supports muscle recovery, and provides long-lasting energy all day long.

Unlike typical gainers, CBUM’s formula keeps the sugar low and the quality high. You get more of what you want—calories, clean carbs, and complete proteins—and less of what you don’t. No fillers. No junk. Just results.

Whether you’re trying to break past a plateau or build serious mass like Chris Bumstead himself, this formula is made to support your journey.

Skip the cheap calories. Feed your muscles right.
