- Grams of protein per serving as printed on this size's own panel: "Protein 24g" in a "Serving size 40g (About 1 Scoop)" serving with "20 servings per container". Nothing here is inherited from the 12-serving bag, whose panel prints a different sweetener and a different Daily Value beside the same 24 g. Net weight is deliberately not recorded for these: the container is powder, the basis is the protein in it, and the two must not be divided into each other. The front face prints "NET WT 28.2 OZ (1.76 LB) 800 G" and "20 SERVINGS". No face read for this tub carries the VEGAN badge the 12-serving bag prints, and none prints a gluten claim, so vegan and gluten free are both Unknown here.

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: $39.99 at Optimum Nutrition (direct), checked . Unchanged since we started checking on Sep 20 (27 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.
- Checked NSF Certified for Sport database on Sep 20, 2026: not listed.
- Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: checked, not listed
Checked and absent. The full Certified for Sport directory read on Sep 20, 2026 carries two Optimum Nutrition rows, both of them the Gold Standard 100% Whey line (1256427 and 1484223), and no row for Gold Standard 100% Plant Protein in any flavor or size. The label on this tub prints no certifier mark of any kind. Absence from a database is not a failed test.

Checked and absent. USP's own Verified Products directory was read page by page in a browser on Sep 21, 2026: 16 pages, 159 products, 16 brands, captured in this site's directory snapshot. This brand does not appear in the directory or in its brand facet, and no product in it names this brand. USP verifies the products a company submits to it, so this records which products were submitted and nothing else. Absence from a database is not a failed test.

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.

LGC's own Informed Choice product list of September 2026, read in full on Sep 24, 2026, prints "ON Gold Standard Plant Protein (USA)" under Optimum Nutrition. That names this product. The list prints no package size, flavor, batch or date, and Informed Choice certifies batch by batch, so the package-scope question that applies to NSF listings does not arise here; a listing from a batch program says the product is in the program, not that any one package or batch was tested.

These are browsing options, not recommended substitutes.
What this rests on: prices we last recorded at the retailer named on each product page, which go stale, and each page says when it was checked; the products we track, not every product sold, and Amazon and Walmart are not among the stores; listings and labels read at the source, each linked from the page.
