The verdict

The industry benchmark for a reason — 24g of quality whey (isolate-forward) per scoop, well-flavored, third-party tested, at a fair per-serving price. Protein is one of the few categories where the big brand is genuinely a good deal. Not much to "DIY" here; this one earns its shelf space.
