About this item
  • HIGH-CALORIE MASS GAIN FORMULA WITH ~27G PROTEIN PER SERVING โ€“ SERIOUS GAINZ by The Bulk Protein Company delivers approximately 460 calories, 27g protein and 74g carbs per serving, helping support a consistent calorie surplus. Designed for hardgainers and anyone looking to increase size and strength, it supports muscle recovery, training performance and steady weight gain when combined with a structured nutrition plan.
  • SUPPORTS MUSCLE GROWTH & POST-WORKOUT RECOVERY โ€“ Each serving provides a balanced blend of protein and carbohydrates to replenish energy after training and support lean muscle growth. The combination of soy protein, whey isolate, casein and oat flour delivers both fast and sustained amino acid release, helping refuel muscles, restore glycogen levels and maintain a high daily protein intake.
  • MIXES BEST WITH MILK FOR A SMOOTHER, MORE ENJOYABLE SHAKE โ€“ As a bulking protein powder, SERIOUS GAINZ can be prepared with water or milk, though many users prefer milk for a smoother, richer and more consistent texture. Adding liquid first, shaking thoroughly or using a blender helps reduce clumps and creates a creamier shake thatโ€™s easier to drink during heavy bulking phases.
  • SMOOTH, SWEET FLAVOUR EXPERIENCE YOU CAN ENJOY DAILY โ€“ 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.
  • FILLING FORMULA DESIGNED TO SUPPORT A DAILY CALORIE SURPLUS โ€“ This mass gainer delivers a dense, satisfying shake that helps maintain daily calorie targets during bulking phases, supporting consistent nutrition intake.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days โ€” so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
