Been taking ON products for years. Always mix well, never clump. Been a stalwart of Vanilla Ice Cream but branched out to Chocolate Peanut Butter. Great to stir through your porridge.

Definitely the best flavour - had used other brands and their flavour are always not good, but this one has the perfect amount of sweetness. Would recommend to anyone willing to upgrade its diet with a protein punch and good taste!
