Quick verdict
Pick ISO100 if you want an isolate‑style whey that’s typically leaner and often chosen by people who prefer a “cleaner” macro profile.
Pick Gold Standard Whey if you want a classic everyday whey with a huge flavour range and broad popularity as an all‑rounder.
If you’re cutting or sensitive to lactose, ISO100 is usually the first shortlist. If you just want a reliable daily whey, Gold Standard is hard to beat.
