Struggling to Hit Your Calorie and Protein Target?

Getting 500 kcal and 34g of protein from whole food alone takes real effort and a real appetite – this shake puts both into one 140g serving.

517 kcal and 7g of Fibre Per Serving

Each 2-scoop (140g) serving provides 517 kcal and 7g of fibre. A 4kg tub works out at roughly 28 servings.

34g of Protein Isolate Per Serving

Each serving provides 34g of protein from Protein Isolate, released steadily over time. Protein contributes to a growth in muscle mass, to the maintenance of muscle mass, and to the maintenance of normal bones.

Great Taste, Easy to Enjoy

Mix into smoothies, oats, or pancake batter – a mass gainer that doesn’t feel like a chore to drink.
