DECATHLON tip: Consume your Gainer as a snack, away from main meals, about two hours after or before a meal. Starting with smaller doses and gradually increasing the quantity will limit digestive discomfort.

What is the difference between Whey and Mass Gainer?

Mass Gainers can sometimes be confused with whey because of their common protein content. And, like whey, Mass Gainer is a practical, economical product that can be easily consumed wherever you are. The main difference between the two products lies in their composition. Unlike whey, which is lower in calories, Mass Gainers offer a significantly higher amount of carbohydrates and calories to support weight and muscle mass gain. If you're looking to build muscle but don't want to gain weight, you're better off using whey.
