- Grams of protein per serving as printed on this package's own panel: 25 g of protein in a 34 g scoop, "Servings Per Container: About 26". Net weight is deliberately not recorded for whey: the bag is powder, the basis is the protein in it, and the two must not be divided into each other. The 907 g on the package front is the label's figure for the same bag, and the panel itself says 34 g per scoop is an average.

Price history
Latest recorded price: $46.95 at Sports Research (direct), checked . Unchanged since we started checking on Sep 19 (22 checks).
This store’s prices are read by hand, less often than daily, 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 Sport.
- Checked NSF Certified for Sport database on Sep 18, 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 of Sep 18, 2026 holds two Sports Research rows, both creatine, and no whey protein row for this brand. Absence from a database is not a failed test.
Source: NSF Certified for Sport, NSF Certified for Sport directory: full read, Sports Research rows · checked Sep 18, 2026USP Verified: checked, not listed
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.

LGC's own Informed Sport product list of September 2026, read in full on Sep 24, 2026, prints "Whey Protein Isolate" under Sports Research. That names this product. The list prints no package size, flavor, batch or date, and Informed Sport 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.
What Informed Sport checks
| Confirms the label’s dose | Not stated |
| Tests for heavy metals / contaminants | Not stated |
| Screens for substances banned in sport | Yes |
| Reviews manufacturing | Paper-based review |
| Testing frequency | Every batch |
From the program's own published description of its process. Source. “Not stated” means the program does not publish a clear answer. It does not mean no.
Informed Choice: checked, not listed
Sports Research is on LGC's own Informed Choice product list of September 2026 with 10 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 Choice certifies the products a company submits, so this records only that this product is not in the program's published list on that date.
Source: LGC (Informed Choice), Informed Choice product list, September 2026 PDF, full read, September 24, 2026 · checked Sep 24, 2026No laboratory report with figures is recorded here for this product.
Not established: Heavy-metal testing, Label-accuracy testing.
Absence of data is not evidence that a product is clean. It means we found no published result for that testing.
