Our Verdict: Optimum Nutrition Serious Mass Banana or Optimum Serious Mass Choc Peanut Butter?
Chocolate Peanut Butter edges ahead with slightly more calories per serving (1,263 vs 1,250 kcal) and added creatine, making it the better pick for serious bulking. However, its sugar content is more than double (26g vs 12g), so those monitoring blood glucose should choose the Banana flavour instead.

Optimum Nutrition Serious Mass Banana vs Optimum Serious Mass Choc Peanut Butter: What Does the Data Say?
Both products are from Optimum Nutrition's Serious Mass range, priced identically at £40 for 2.73kg, and score the same 70/100 overall. The key differences lie in the nutritional profile. The Banana flavour delivers 1,250 kcal per serving with 12g of sugar, while the Chocolate Peanut Butter version pushes that to 1,263 kcal but comes with a notably higher 26g of sugar per serving — more than double. The Chocolate Peanut Butter also includes 3g of creatine monohydrate per serving, which the Banana version lacks, and carries a higher sodium level at 1.56g per serving (26% of the RDA).
If you're watching your sugar intake or are sensitive to sodium, the Banana flavour is the more sensible pick. It's also praised for taste, with reviewers describing it as genuinely enjoyable. The Chocolate Peanut Butter suits those who want the added creatine benefit bundled in without buying it separately, though the sugar load is worth flagging for anyone managing blood glucose. Both use a whey and casein protein blend for sustained release throughout the day.
