Best Review
Customers enjoy the taste of the protein supplement powder. They find it tasty and not overly sweet. Many say it helps them gain weight and muscle mass. The good composition of carbs and protein provides a substantial calorie and protein boost. However, some customers are disappointed with the size and stomach discomfort. There are mixed opinions on mixing ability.AI-generated from the text of customer reviews
