## At a glance

- Unflavoured powder with 25 servings stated in the title.
- The listing claims 31 g protein and 50 g complex carbohydrates per serving.
- The described carbohydrate blend includes maltodextrin and oat flour.
- The manufacturer suggests mixing in a shaker or blender and mentions post-training or between-meal use.

## 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.

- People looking specifically for a vegan or plant-based powder.

## Customer feedback

Aggregate ratings lean positive overall, with the five-star category forming the largest share, but the sample is small and there are also lower ratings. This offers only a limited indication of customer sentiment and does not establish specific strengths or drawbacks. Consider the claimed calorie and carbohydrate levels when deciding whether the product matches your intended use.
