Pros and cons

Pros

Provides a stated high-calorie serving alongside both protein and complex carbohydrates, which may suit buyers deliberately increasing calorie intake.
Unflavoured format leaves room to combine it with other drinks or ingredients, though the listing does not specify mixing recipes.

Cons

The stated 388 calories and 50 g of carbohydrates per serving make this a poor fit for shoppers seeking a low-calorie or low-carbohydrate protein powder.
The blend is whey-based, so it is not presented as a plant-based option.
