What does the data say about Critical Mass Professi... vs Critical Mass Professi...?

Both products carry the Applied Nutrition Critical Mass Professional name, but the scores tell a clear story. The Banana 2.4kg scores 80/100 overall against the Vanilla 6kg's 71/100, with the gap widest on effectiveness: 90/100 versus 73/100. The Vanilla version does bring a more detailed ingredient profile on paper — 42g of ISO-XP 95% Whey Protein Isolate per serving, plus creatine monohydrate, HMB, leucine, and glutamine. The Banana version doesn't list those specifics in the data, but user-reported results within 2-4 weeks suggest it delivers in practice despite the lower ingredient quality score of 80/100 versus 70/100.

The Banana 2.4kg at £40.00 makes sense if you want faster visible results and aren't ready to commit to a bulk buy. It scores 80/100 for value, and at 16 servings it's a lower-risk entry point. The Vanilla 6kg costs £62.76 for 40 servings, which works out cheaper per serving, and it suits hard gainers or those in a structured off-season phase who already know a mass gainer works for them and need the supply to last. Its value score of 76/100 is decent but trails the Banana version.

Practically, the Vanilla 6kg's 150g serving size needs a blender — shaker alone causes clumping. That's a real inconvenience for busy mornings. The Banana version has its own problem: the flavour is reported as strong enough to overwhelm at full portions, so starting with less liquid or a smaller scoop is sensible. Neither product is subtle on calories, with both exceeding 1,000 per serving, so anyone not consistently hitting their training sessions could accumulate unwanted fat regardless of which they choose.
