- Grams of protein per serving as printed on this package's own panel: "Protein 21 g" in a "Serving Size: One Scoop (30.2 g)" serving with "Servings Per Container: 30". The panel also prints "Whey Protein Isolate 25 g" on a separate line; the protein line is what the comparison uses, as it does for every other product in this category. The tub prints "NET WT. 31.9 OZ (1.99 LB.) 906 G"; net weight is deliberately not recorded for whey, because the basis is the protein in the tub and the two must not be divided into each other. The same scoop carries a 30 mg Proprietary Blend of bromelain and papain, which is priced nowhere.

Price history
Latest recorded price: $65.00 at Thorne (direct), checked . Unchanged since we started checking on Sep 20 (38 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 A: Independently certified
This exact package is inside the certifier’s own scope: named on an NSF Certified for Sport listing, or, for USP Verified, the product is in USP’s directory and its mark is on this package’s label. Both audit the manufacturing site and both confirm the label’s own claims against the finished product. They are not interchangeable beyond that: NSF Certified for Sport also screens for substances banned in sport, and USP Verified does not. USP instead checks that the product dissolves and releases within a specified time. What each program checks is set out per program below.
- Current listing found: NSF Certified for Sport.
- Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: currently listed (1513727)
The listing prints Package Size "30.2 g, 906 g", Serving Size "1 scoop (30.2 g)" and Protein 21 g. This tub's front face prints "NET WT. 31.9 OZ (1.99 LB.) 906 G" and its panel prints "Serving Size: One Scoop (30.2 g)", "Servings Per Container: 30" and "Protein 21 g", so the listing names the exact package sold and agrees with the panel line the comparison uses. The listing is flavor-specific (Flavor Chocolate); the vanilla tub has its own row, 1513728.

USP 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.
