Our Verdict: Optimum Nutrition Serious Mass Banana or Optimum Serious Mass Cookies & Cream?
Cookies & Cream edges ahead on value: at £58 for 5.4kg it works out significantly cheaper per serving than the Banana 2.73kg at £40, while both score identically across all criteria. It also adds 3g creatine monohydrate per serving, giving a genuine performance benefit. Choose the Banana tub if you want a smaller upfront spend or simply prefer that flavour.

Optimum Nutrition Serious Mass Banana vs Optimum Serious Mass Cookies & Cream: What Does the Data Say?
Both products are essentially the same formula — 1,250 kcal and 50g protein per serving, with maltodextrin as the primary carbohydrate source and identical scores of 70/100. The meaningful differences are size, flavour, and one notable extra: the Cookies & Cream 5.4kg contains 3g of creatine monohydrate per serving, which the Banana 2.73kg does not. That creatine addition could support strength and performance gains without needing a separate supplement.
If you're new to mass gainers or unsure whether you'll stick with it, the Banana 2.73kg at £40 is the sensible starting point — lower commitment, lower outlay. The Cookies & Cream 5.4kg at £58 works out cheaper per serving and suits anyone already committed to a long bulking phase, particularly if they want that creatine bump included. The sugar content (12g per serving) and heavy maltodextrin load are worth noting for anyone sensitive to energy crashes. Both mix as powders, so taste preference — banana versus cookies and cream — may genuinely be the deciding factor for daily use.
