Setup (Preparation): To prepare your shake, mix one serving (scoop amounts may vary, check packaging) of Optimum Nutrition Gold Standard 100% Whey with 6-8 fluid ounces (approximately 180-240ml) of cold water or milk in a shaker cup. Shake well for 20-30 seconds until the powder is fully dissolved. For a thicker shake, use less liquid. For a thinner shake, use more. You can also blend it with ice, fruits, or other ingredients for a personalized smoothie. Compatibility: This product is compatible with most fitness regimens and dietary goals focused on increasing protein intake for muscle development, weight management (due to low calorie, sugar, and fat profile), and general health. It contains dairy (whey protein), so it is not suitable for individuals with dairy allergies or who are lactose intolerant. It is a protein supplement and should be integrated into a balanced diet, not used as the sole source of nutrition. Care (Storage): Store in a cool, dry place away from direct sunlight and moisture. Ensure the container is tightly sealed after each use to maintain freshness and prevent clumping. Do not store in a refrigerator unless specifically instructed by the packaging. Keep out of reach of small children.
