Mass Gainer Proteins

Of course! At decathlon.com.gr you will find a wide variety of mass gainer protein powders designed for muscle growth and weight gain. The collection includes products from specialized Decathlon brands, packed with high-quality carbohydrates, whey protein, and great flavors.

The main difference lies in caloric density! While standard whey contains almost exclusively protein (70-80%) with minimal fat and carbs, mass gainer combines protein with a high ratio of complex and simple carbohydrates (such as maltodextrin or oats).
Additionally, it is often enriched with creatine, amino acids (BCAAs), vitamins, and minerals for optimal recovery and muscle building.

It depends on the type of gainer! A typical serving usually provides between 350 to 600+ calories, with 50-90 grams of carbohydrates and 20-40 grams of protein.
In so-called "extreme gainers," calories can even exceed 1,000 per full serving, which is why you can easily adjust your dose (scoops) based on your daily caloric needs.

The ideal time to consume mass gainer protein is immediately post-workout, as carbohydrates quickly replenish muscle glycogen while protein initiates muscle repair.
Alternatively, you can take half a serving as an in-between snack during the day to ensure you reach the caloric surplus required for muscle growth.

Fat gain depends entirely on your total caloric surplus! If you consume excessive calories far beyond what your body burns, a portion will be stored as fat.
To gain mostly lean muscle mass, pair your mass gainer with intense strength/weight training and aim for a controlled daily caloric surplus of around 300-500 calories.

If you have a very fast metabolism that struggles to gain weight, or if you have high caloric demands due to intense training sessions, then a mass gainer is a great choice.
It is also ideal for anyone who finds it difficult to consume large volumes of solid food throughout the day.
