  • Promotes mass gain effectively.
  • Offers excellent value for money.
Main Highlights
  • HIGH-CALORIE MASS GAIN FORMULA WITH ~27G PROTEIN PER SERVING – SERIOUS GAINZ by The Bulk Protein Company delivers approximately 460 calories, 27g protein and 74g carbs per serving, helping support a consistent calorie surplus.

Adding liquid first, shaking thoroughly or using a blender helps reduce clumps and creates a creamier shake that’s easier to drink during heavy bulking phases.
  • SMOOTH, SWEET FLAVOUR EXPERIENCE YOU CAN ENJOY DAILY – This mass gainer delivers a rich, dessert-style taste that makes each shake enjoyable as part of your daily bulking routine. Available in flavours such as Chocolate, Cookies & Cream, Vanilla, Strawberry and Banana, it suits both classic and indulgent preferences.
