Critical Mass Professional Lean ...

Pros

✓1,000+ calories per serving well-suited to hard gainers who struggle to hit caloric surplus
✓Informed Sport registered — meaningful third-party quality and contamination testing
✓Comprehensive formula beyond just protein: creatine monohydrate, HMB, glutamine, CLA, and MCT
✓Reduced-sugar formulation compared to older mass gainers — favourable for lean bulk

Cons

✗Taste inconsistency across batches — some report a chemical or medicinal aftertaste in the strawberry flavour
✗150g per serving is a very high volume, potentially difficult for smaller individuals or those with lower appetite
✗Not vegan — whey-based formula unsuitable for plant-based users
✗1,000+ kcal per serving requires careful use; excess can lead to unwanted fat gain if training volume is not sufficient

Best For

Hard gainers with high metabolic rates struggling to maintain caloric surplus Athletes in off-season or dedicated bulking phases Post-surgery or illness recovery requiring rapid caloric replenishment Halal diet followers seeking a certified mass gainer Intermediate lifters wanting an all-in-one mass-gain stack without separate creatine or HMB supplements

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

The banana 2.4kg tub scored 80/100 overall against the strawberry 6kg's 74/100, and the gap is most obvious in effectiveness — 90/100 versus 73/100. Both deliver 1,000-plus calories per serving, but the strawberry 6kg formula includes creatine monohydrate, HMB, glutamine, CLA, and MCT alongside the protein base. The banana version's ingredient data is less detailed in the available information, yet it outscores the strawberry across every single category, including ingredient quality at 80/100 versus 76/100.

The banana 2.4kg at £40.00 makes sense if you want a shorter commitment — 16 servings to test whether the product suits you, with users reporting visible results within two to four weeks. The strawberry 6kg at £52.95 gives 40 servings, which works out cheaper per scoop, and suits hard gainers or those in a dedicated bulking phase who already know mass gainers agree with them. The value score tells the real story though: banana scores 80/100 for value versus 71/100 for the larger tub, so the per-serving maths does not automatically favour the bigger bag.

On taste, the banana flavour gets positive reviews for consistency and enjoyment, which matters when you are drinking something daily. The strawberry has a known issue — some batches reportedly develop a chemical or medicinal aftertaste. The 150g serving size on the strawberry version is also a practical hurdle; mixing that volume takes effort and may be difficult if your appetite is modest to begin with.
