- Grams of protein per serving as printed on this size's own panel (GSW_DRC_5lb_NFP.jpg): 24 g of protein in a 31 g scoop, 74 servings per container. Net weight is deliberately not recorded for these: the tub is powder, the basis is the protein in it, and the two must not be divided into each other. The 5.05 lb on the package is the storefront's figure for the same tub.

Delivery terms and limits
Standard delivery in the US is free on orders over $75 and costs $5.99 below that, from the delivery chart on Optimum Nutrition's Delivery Information page, read October 2, 2026. The storefront's announcement bar has read "Free shipping on orders above $75" since at least September 7, 2026. Subscription orders also ship free at any size, but that is a different purchase from the one-time price shown here.

Price history
Latest recorded price: $131.99 at Optimum Nutrition (direct), checked . Unchanged since we started checking on Sep 19 (28 checks).
We check each price about once a day, so this is the range we recorded, not necessarily every price there has been. It says what changed, not why, and nothing about where the price goes next.
Verification, Tier B: Independently tested
A third party with no commercial stake in the product has tested it and published the result: Informed Sport, Informed Choice, IFOS, BSCG, or an independent laboratory. What that testing covers varies by program and is not always what you would assume: Informed Sport and Informed Choice screen finished batches for substances banned in sport and review manufacturing procedures on paper, which is not the same as confirming the label’s dose or testing for heavy metals. The listings below say which program this is, so you can check what it actually covers.
- Current listing found: Informed Choice.
- NSF Certified for Sport lists this product, but the listing does not cover the package size shown here. Listing read Sep 19, 2026. NSF listing 1256427 is brand Optimum Nutrition, "GOLD STANDARD 100% WHEY DOUBLE RICH CHOCOLATE", Product Form Powder, Flavor Chocolate, Package Size "4.53 kg", Serving Size "1 scoop (30.4 g)", Protein 24 g. The panel on the package priced here prints a 31 g scoop and 74 servings, and the four sizes sold are 0.68 lb, 1.98 lb, 5.05 lb and 10.18 lb. 4.53 kg is 149 servings at the listing's 30.4 g scoop. The brand's own product page also carries a separate "Double Rich Chocolate - NSF / 10 lb" variant that its store feed does not price, which may be the package the listing names. The package priced here is not the one the listing prints, so it is listed at another size: the same product and flavor, a package the listing does not name as this label prints it.

USP Verified: checked, not listed
USP Verified covers vitamins, minerals, multivitamins, fish oil and probiotics, and has no protein or sports category. Its public product listing was read on Aug 25, 2026 and enumerates every participating brand: Nature Made, Kirkland Signature, Member's Mark, trunature, Natrol, Nature's Bounty, vitafusion, YouTheory, Culturelle, Estroven, Flomentum, L'il Critters, Move Free, Nature's Lab, Pure Alaska Omega and Ritual. Optimum Nutrition is not among them. Absence from a database is not a failed test.

LGC's Informed Choice list of September 2026, read in full on Sep 24, 2026, prints "ON Gold Standard 100% Whey" under Optimum Nutrition with no region, beside "Gold Standard 100% Whey (EU)", "ON Gold Standard 100% Whey (India)" and "ON Naturally Flavored 100% Whey Gold Standard". The same block marks some lines with a region, EU, India and for some other products USA, and gives this line none. The label image for this tub carries the Informed Choice mark. Since October 8, 2026 this site reads the line with no region as this US Gold Standard 100% Whey; the list itself does not say which region the line covers. The list prints no package size, flavor or batch, so the package-scope question that applies to NSF listings does not arise here.

Informed Sport: checked, not listed
Optimum Nutrition is on LGC's own Informed Sport product list of September 2026 with 9 product lines, read in full on Sep 24, 2026, and none of them names this product. Absence from a list is not a failed test: Informed Sport certifies the products a company submits, so this records only that this product is not in the program's published list on that date.
