Chocolate BlissI had a friend recommend my this product as most protein powders I’ve tried are usually chalky, lumpy and just don’t taste nice. After trying this I found it’s very smooth with milk or water and actually tastes like a milkshake. Will definitely be buying this again and also happy with the price ranges too
