What is a mass gainer
A mass gainer is a blend of carbohydrates and protein for people who struggle to put on weight. One serving provides 400 to 1,000 kcal, making it easier to reach a calorie surplus without extra meals.
Who is a gainer for
- Naturally slim people with a fast metabolism.
- Anyone who trains hard and cannot eat enough calories from food.
- Athletes in a bulking phase.
If you gain weight easily, regular protein is the better choice: extra carbs will not end up in your muscles.
High-carb or high-protein
- Classic gainer (up to 15–20% protein): maximum calories for fast weight gain.
- Lean gainer (25–35% protein): cleaner muscle gain with less unwanted fat.
How to take it
A gainer is usually taken after training and between main meals. Start with half a serving to check how you tolerate it, and track your progress: 0.5–1 kg a month is a healthy pace.
