Comparisons / ON Serious Mass vs Nutrabay Gold Mass Gainer
# Verdict: ON Serious Mass Wins for Serious Bulkers **ON Serious Mass takes this decisively** with a 7.4/10 versus 6.4/10, despite costing ₹6.19 more per serving. The gap comes down to **formula quality**. ON scores a perfect 10.0 on formula versus Nutrabay's 5.0 because it delivers a complete micronutrient profile alongside macros—you're getting 29.94mg magnesium, 5.99mg zinc, and nearly 1g creatine monohydrate per serving. Nutrabay lists only basic macros: 22.36g protein, 67.03g carbs, and 390.66 calories, without additional performance ingredients. **The dosing reversal is notable**: Nutrabay scores 6.0 versus ON's 2.0, suggesting ON requires larger serving sizes to hit its nutritional targets, which some find inconvenient. **Value-wise**, ON dominates at 8.9 versus 5.5, meaning despite the higher absolute price, you're getting significantly more nutritional bang per rupee. **Choose ON Serious Mass** if you want a comprehensive mass gainer with added creatine and minerals for ₹106.09. **Choose Nutrabay** only if the ₹6 savings matters more than ingredient depth, or if you prefer smaller serving sizes.
