Buying Guide
- Nutrient composition: For bulking, look for products with high protein per serving (ideally 20–54 g) and substantial carbohydrates. Some mass gainers include added creatine and BCAAs to aid training performance and recovery.
- Calories per serving: Mass gainers can range from 400 to over 1000 calories per serving. Choose based on your daily caloric target and appetite, adjusting as you progress.
- Macronutrient balance: If you are aiming for lean bulking, prefer options with higher protein and controlled sugar. For clean mass gain, lower sugar and higher-quality carbohydrate blends are preferable.
- Ingredient quality: Consider creatine monohydrate and BCAAs included in the formula, as well as added HMB or glutamine, which may support recovery and muscle synthesis.
- Allergen and flavour preferences: Flavour variety (vanilla, chocolate, cookies & cream) can affect adherence. Check for potential allergens and artificial additives if relevant.
- Mixability and taste: Read reviews on mixability and flavour satisfaction, as a powder that is easy to mix and enjoyable to drink encourages consistency.
- Usage rhythm: Mass gainers are often used post-workout or as a between-meal supplement. Align the timing with your training schedule and appetite to meet protein and calorie goals.
- Health considerations: If you have pre-existing conditions or take medications, consult a healthcare professional before starting any high-calorie supplement plan.
