Critical Mass Strawberry vs Optimum Serious Mass Cookies & Cream: What Does the Data Say?
Applied Nutrition's Critical Mass comes in at £52.95 (score 74.0) versus Optimum Nutrition's Serious Mass at £58.00 (score 70.0), but the cheaper option doesn't necessarily mean better value. Critical Mass delivers 1,000+ calories per serving with added creatine, HMB, glutamine, CLA, and MCT oil — a formula that goes beyond basic protein. Serious Mass packs more calories (1,250 per serving) and delivers stronger effectiveness (80.0 vs 73.0), though it contains 12g sugar per serving and simpler carbohydrates like maltodextrin.
The practical difference matters most. Critical Mass's 150g serving size is huge — difficult if you're not already eating large meals. Serious Mass users consistently praise the taste and mixability.
Choose Critical Mass if you want ingredient depth and lower cost, particularly for hard gainers comfortable with larger servings. Pick Serious Mass for superior taste, higher calorie density, and stronger measured effectiveness — though you'll pay a bit more and deal with higher sugar content.
