2 of 24 supplement brands post a lab report for their product

Findings

1. Two of 24 supplement brands post a lab report for their product, both of them C60 oil brands, and 3 more share reports only on request.
2. Seven advertise third-party testing, lab testing or a certificate of analysis with no document posted.
3. Eight print a label that disagrees with their own page text or their own lab report.
4. Four ketone brands print a sport or drug-free certification, and the program's own database lists the exact flagship product for 2 of them.
5. Six of the 10 patch brands print an ingredient list with no Supplement Facts panel, and 2 say on their sites that their patches are not dietary supplements or use a cosmetics disclaimer.
6. A serving costs a median of $4.99 for ketone drinks (9 brands), $0.97 for patches (10) and $3.21 for C60 oil (3).
7. Five brands promise a money-back or satisfaction guarantee that their written return policy narrows.

How to read these numbers. A brand posts a lab report when a report for its product is on its site for anyone to read. Reports sent only on request, and claims of testing in page copy or badges, do not count. We read each brand's own site on 25 September 2026 and did not test any product. This bulletin describes what brands publish, not what their products do, and names no brand.

Lab reports are rare in all three categories. None of the 9 ketone brands and none of the 10 patch brands post one. Two of the 5 C60 oil brands do: one posts lot-numbered reports that include heavy metals and microbial tests, and one posts a single comparison test from 2016. Three brands, 2 of them ketone brands, share reports only when a buyer asks.

The gap between claims and documents is wider. Seven brands put "third-party tested", "lab tested" or a reference to their certificate of analysis on their pages or product images with no report on the site. In one case the product image points to a certificate of analysis that appears nowhere on the site.

Labels and pages that disagree

Eight brands print a label that disagrees with their own site. The cases include a ketone amount on the homepage that is higher than the flagship's label, a page that calls a patch caffeine-free while its label lists guarana and green tea extract, and an ingredient amount that differs by a factor of ten between label and product page. Two patch brands print amounts that are not the patch's own content, such as figures stated as pill equivalents.

Certifications

Only ketone brands print a sport or drug-free certification. Three name the program. When we looked the flagship up in each program's own database, 2 were listed by name, and the third was listed in other flavors of the same line but not in the flavor the brand features first. The fourth brand says its product is certified drug free without naming who certified it.

Patch labels

Patches present themselves in three ways. Three brands print a Supplement Facts panel, one prints a "Nutritional Facts" panel, and 6 print an ingredient list with no facts panel. Two say on their sites that their patches are not dietary supplements or use the disclaimer written for cosmetics.

What a serving costs

Ketone drinks and supplements4.99 USD

Vitamin and supplement patches0.97 USD

Source: each brand's own store, read on 25 September 2026. One-time price of the smallest standard pack of the brand's flagship product, divided by the servings on its label. Ranges are in price-per-serving.csv.

Ketone drinks run from $2.00 to $39.00 a serving across 9 brands, a median of $4.99. Patches run from $0.50 to $6.74 across 10 brands, a median of $0.97. Three C60 oil brands print a serving size, and their price per serving runs from $2.70 to $5.65.

Returns and guarantees

Fourteen brands state a 30-day return window, 3 allow longer and 2 allow less. Five promise a money-back or satisfaction guarantee on a product page while their written policy accepts only unopened products, gives store credit for opened ones or limits refunds to first orders.

Method

Sources. Each brand's flagship product page, its label or Supplement Facts image, its quality, testing and certification pages, FAQ and refund policy, read on 25 September 2026. Certification claims were checked in the certification program's own public database where one could be reached. Label images were read with on-device text recognition and key figures were checked by eye.

Sample. Seventeen brands from a starting list of brands named in buyer discussions and AI assistant answers, and more found through web searches on 25 September 2026, up to 5 per category. Two brands whose stores were not working are left out, and two domains that belong to one company are counted once. That leaves 24 brands: 9 ketone drink and supplement brands, 10 patch brands and 5 C60 oil brands.

Definitions.

• The flagship is the product the brand's own site ranks first: a best-seller badge, the first item in a best-seller block, the homepage hero or the first item in the brand's product menu.
• A lab report is posted when a report for the brand's product can be read on its site. Current reports are lot-numbered reports for successive batches. A sample report is a single old or example report not tied to current batches.
• Price per serving is the one-time price of the smallest standard pack of the flagship, before coupon codes, divided by the servings on its label.
• A guarantee is narrowed when a product page promises a money-back or satisfaction guarantee and the written policy limits it.

Exclusions. Marketplace listings were used only to find brands. Brands selling only outside the US in foreign currency were left out.

Names. This bulletin reports totals and names no brand.

Known limits. Categories are small, and the C60 oil price comparison rests on 3 brands. We did not request reports that are offered on request.
