- Printed on this bottle's own panel image (ONUS-glutamine-capsules_Label_240-capsules_120-servings.jpg) as "L-Glutamine 1g*" in a "Serving Size 2 Capsules" serving, with "Servings Per Container 120"; the same image prints "240 CAPSULES", and 120 servings of 2 capsules is 240. The comparison basis is grams of L-glutamine and the panel prints grams, so nothing is converted; the panel names L-glutamine and no other dietary ingredient. The other ingredients are recorded as printed, "Gelatin, Magnesium Stearate." The capsule is gelatin, so the product is not vegan or vegetarian. No gluten or allergen statement is printed, so both are Unknown.

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. Read again on October 17, 2026, with the same chart row.

Verification, Tier D: Could not locate independent data
We could not locate independent testing or certification for this product. That is a statement about our search, not about the product. These programs certify what a company submits to them, so a product can be absent simply because it was never entered, which is not a finding against it. Which certifier databases we searched, and when, is listed below. Where a program is not listed there, we have not checked it and do not imply anything either way.
- Searched 4 certifier databases and found no listing for this product, and located no published test results. A program not named below was not checked for this product.
- Checked NSF Certified for Sport database on Oct 30, 2026: not listed.
- Checked USP Verified database on Sep 21, 2026: not listed.
NSF Certified for Sport: checked, not listed
Checked and absent. NSF's whole Certified for Sport directory was read on Oct 30, 2026, 2,593 listings, and holds two Optimum Nutrition rows, 1256427 "GOLD STANDARD 100% WHEY DOUBLE RICH CHOCOLATE" and 1484223 "Gold Standard 100% Whey Vanilla Ice Cream", both the Gold Standard 100% Whey line; none of the 14 listings whose product name contains "glutamine" is this brand's. The panel image read for this package prints no NSF mark. Absence from a database is not a failed test.
