Buying Guide
What to consider when choosing a mass gainer
Calorie target: Choose a product with calories aligned to your bulking goals. Higher calories per serving support faster gains but require careful meal planning.
Protein per serving: Look for at least 40–50g protein per serving to support muscle repair and growth, especially when training intensely.
Carbohydrates: A high carb load fuels workouts and helps replenish glycogen. Consider total daily carbohydrate needs to avoid excessive sugar.
Protein sources: A mix of whey, casein, and sometimes hydrolyzed whey can improve absorption and amino delivery over time.
Ingredient quality: If you prefer natural or NSF-certified products, review ingredient lists and certifications.
Digestibility: Some weight gain powders include digest enzymes or blend types that may affect tolerability. Consider lactose tolerance when selecting dairy-based formulas.
Flavor and mixability: Flavor variety and how well the powder mixes can affect adherence during a bulk period.
