What is Optimum Nutrition Gold Standard Protein (5 lbs)? It is the 5 lb value tub of the world's best-selling whey protein, with whey protein isolate as the primary source. Each ~30.4g scoop delivers 24g of protein, about 5.5g of naturally occurring BCAAs and 4g+ of naturally occurring glutamine and glutamic acid. This large tub mixes instantly, is gluten-free, and gives the best cost-per-serving in the Gold Standard 100% Whey lineup.
About Optimum Nutrition
Optimum Nutrition (ON) is one of the most trusted names in sports nutrition, and Gold Standard 100% Whey is its flagship — the benchmark other whey proteins get measured against. It uses whey protein isolate as the number-one ingredient, supported by ultra-filtered whey concentrate and hydrolyzed whey.
Why we carry it
Gold Standard is the reliable default we recommend when someone wants a no-surprises whey: it mixes clean, tastes consistent across flavors, and the macros are exactly what they claim. The 5 lb tub is the size for daily users and households — the same trusted formula at the lowest price per serving.
Key features
- 24g protein per scoop, whey isolate as the primary source
- ~5.5g naturally occurring BCAAs per serving
- 4g+ naturally occurring glutamine & glutamic acid
- Instantized for easy mixing with a glass and spoon
- Informed Choice certified — batch-tested against banned substances
- Gluten-free; nearly 79% protein by weight
- Select flavors carry OU-D kosher certification — check the label
- 5 lb tub (about 73 servings) — best value size
Who it's for
Anyone building or maintaining muscle — beginners through advanced lifters — who wants a dependable, fast-digesting protein for post-workout or daily intake, and who goes through protein fast enough to buy the big tub.
Best value: why the 5 lb tub wins on price
At $149.99 for about 73 servings, the 5 lb tub works out to roughly $2.05 per 24g-protein serving. The 1.5 lb tub ($64.99 for about 22 servings) is about $2.95 per serving — so the big tub is roughly 30% less per shake, about $0.90 saved every serving. If you drink a shake most days, the 5 lb pays off fast and means fewer reorders. Want to try a flavour first? Start with the 1.5 lb size, then size up.
