Buying Guide: Key Considerations For Mass-Building Purchases
- Calorie goals: Higher-calorie gainers support rapid mass gain but require matching training and appetite management. For steady growth, balance calories with protein and carbohydrates to optimise recovery.
- Protein quality and type: Whey isolates and blends offer fast absorption, while casein provides slower release. For vegans, plant-based blends are available with varied amino profiles.
- Carbohydrate profile: Complex carbohydrates support sustained energy. Assess sugar content and the presence of maltodextrin or added fibres for digestion and satiety.
- Creatine inclusion: Some formulas include creatine to enhance strength and recovery. If desired, consider products with creatine monohydrate for best evidence-backed results.
- Flavour and palatability: Taste influences adherence. Look for options with natural flavouring and smoother finishes to avoid taste fatigue during long cycles.
- Digestibility: Enzymes or digestive aids can improve tolerance, particularly for those prone to GI discomfort with dense shakes.
- Allergen considerations: Check for dairy, soy, gluten, or vegan formulations if you have dietary restrictions or sensitivities.
- Meal timing: Use mass gainers around workouts or as meal supplements to fit daily calorie targets, while matching protein intake to support muscle protein synthesis.
- Cost and practicality: Larger tubs reduce cost per serving but weigh into storage and shelf life. Pick sizes that match your training plan and budget.
- Regulatory and health guidance: Consult a healthcare professional for long-term use, especially if you have health conditions or are taking medications.
