Optimum Nutrition Serious Mass - Banana 6lb
What it is
Optimum Nutrition Serious Mass is a high-calorie weight gainer delivering around 1,250 calories and 50g of protein per two-scoop serving, plus over 250g of carbohydrates and added creatine, glutamine and vitamins, to help hard-gainers build size and mass. It is best used alongside your regular meals to reach a calorie surplus. This 6lb tub in Banana provides about 8 servings.
Banana in the 6lb: enough to find out whether the flavour suits you without being landed with sixteen servings.
Who it's for
Hard-gainers bored of chocolate and vanilla, or those who blend their shakes with real fruit and want the flavours to match up.
How to use it
Blend two scoops with water or milk once or twice a day between meals or after training.
Worth knowing
Contains milk. If you are unsure about banana-flavoured powders generally, buy chocolate instead — a half-finished gainer helps nobody.
Our take
Banana divides opinion more than the other two flavours — people who like it really like it, and the rest go back to chocolate, so we would rather you tried it at 6lb than in the big tub. Everything else matches the standard Serious Mass: same 1,250 calories, same creatine and vitamins.
