Serious Mass Flavours
When it comes to hard gainers or endurance athletes alike it can sometimes seem impossible to eat sufficient calories. Optimum Nutrition makes your calories seem effortless with the following delicious flavours:
Banana - A more subtle and complex flavour than you would expect. Deliciously creamy start to finish.
Chocolate - A rich dairy chocolate taste, no over-powering artificial aftertaste.
Vanilla - Delicious vanilla cream, no clump at all not too sweet.
Strawberry - Sweet strawberry milkshake, smooth and soft all at the same time.
Very happy with my products they came fast and were packaged nicely
Great product taste is good, using for nearly 2 weeks now starting to see weight gain. Thanks a lot will be buying more.
