What it is
Optimum Nutrition Gold Standard Whey is one of the best-selling protein powders in the world, a whey blend that mixes easily and comes in a large flavor range. It has been a default recommendation in gyms for a long time.
The evidence
Protein is one of the most useful supplements for people who train or struggle to hit protein targets from food. Whey is well absorbed and effective for supporting muscle. The specific brand matters less than total daily protein, but a clean-mixing, reasonably priced whey like this makes hitting your target easy.
Who it is for
A safe default for most people who want a tasty, affordable whey. If you are very sensitive to lactose or want the leanest possible macros, a pure whey isolate may suit you better.

Frequently asked questions
Isolate or this blend?
For most people the blend is fine and cheaper. Choose an isolate if you are quite lactose sensitive or counting every gram of carbs and fat.
How much protein do I need?
Many active people aim for roughly 1.6 to 2.2 grams per kilogram of body weight per day from all sources.
