Overview
We keep Optimum Nutrition Gold Standard 100% Whey Muscle Building and on our protein powder shelf alongside 44 others, and rank it on rating, review volume and live price rather than on the brand. The manufacturer puts it this way: Designed for goal-driven athletes and fitness lovers, fast-absorbing Gold Standard Whey with whey protein isolate supports muscle growth and repair after a workout. Our award-winning formula contains naturally occurring BCAAs and glutamine, plus 24 grams of quality, fast-absorbing whey protein powder per serving. That is the maker talking, not us, so read it as a claim rather than a finding. Buyers have it at 4.6 out of 5 from 28,700 ratings. We work out below what that is worth against everything else on the shelf.

How it compares on the protein powder shelf
Across the 45 rated protein powder products we track, the middle of the pack sits at 4.4 out of 5. This one scores 4.6. That sits mid-table. Ratings this close together don't decide anything on their own, so weigh pack size, price per unit and the specifics below instead. Weighted for review volume, we place it third on this shelf.
28,700 people rated it, where the shelf median is 474. A score built on that many opinions is hard to shift and hard to game, which is why we weight review volume rather than ranking on stars alone.
On money, this sits in the middle third of a shelf running from £14.64 to £170, with the midpoint around £46.40. That's where most sensible buys land, neither the cheapest thing on the shelf nor the one you pay a name for.
