It’s a whey blend with 24 g protein per serving, has a long track record, and recent independent testing found the Chocolate Malt version had an A+ Labdoor grade with 100/100, passing purity and label-accuracy testing.

My picks by goal

• 🥇 Best overall/value: Optimum Nutrition Gold Standard 100% Whey
• 💪 Best premium whey isolate: Transparent Labs Grass-Fed Whey Isolate — 28 g protein/serving.
• 🥛 Best if lactose bothers you: Whey isolate, such as Transparent Labs or Dymatize ISO100.
• 🌱 Best vegan: A pea + rice protein blend; these provide a more complete amino-acid profile than relying on many single-source plant proteins.
• 💰 Best budget approach: Whey concentrate rather than isolate—you generally get more protein per dollar if you tolerate dairy.
