ON Serious Mass vs MuscleBlaze Mass Gainer XXL

# Verdict: ON Serious Mass Wins for Serious Gainers **ON Serious Mass** is the clear winner with a 7.4/10 overall score versus MuscleBlaze's 6.1/10, despite costing ₹3.86 less per serving at ₹106.09. The decisive factor is **formula quality**: ON scores a perfect 10.0 while MuscleBlaze manages only 4.8. ON includes creatine monohydrate (898mg per serving), which directly supports muscle growth and strength—something MuscleBlaze lacks. The zinc (6mg) and magnesium (30mg) in ON also aid recovery and testosterone production. However, ON's major weakness is **dosing convenience** (2.0/10), likely requiring multiple servings daily. MuscleBlaze scores better here (5.6/10) and provides complete macronutrient transparency: 382.5 calories with 15g protein, 75g carbs, and 3g fat per serving. Its 500mg glutamine supports recovery, and 3g fiber aids digestion. **Choose ON Serious Mass** if you prioritize ingredient quality and don't mind larger serving requirements. **Choose MuscleBlaze XXL** if you want straightforward macro tracking and better per-serving convenience. For pure muscle-building effectiveness, ON's superior formula justifies its 1.3-point lead.
