Best Questions to Ask a CBD Brand

September 25, 2026 at 7:07 am

The best question to ask a CBD brand is simple: "Can I see the lab report for the batch I am buying?" A good brand answers quickly, with a report you can match to your bottle. The other questions on this list build on that one, covering who did the testing, what was tested, how THC is measured, and how the brand talks about what CBD can and cannot do.

You need to ask because the label alone is not enough. The FDA has not approved any CBD product other than one prescription drug, and it states that CBD products are excluded from the dietary supplement definition (FDA). That leaves quality checks largely up to brands and the people who buy from them. When the FDA tested products it had sent warning letters to, many did not contain the levels of CBD they claimed (FDA).

Here are ten questions worth sending before you buy, what a solid answer looks like, and what should make you pause.

Key takeaways

Ask for a batch-specific certificate of analysis (COA), not a sample report.
Ask what the finished product was tested for, and what the raw ingredients were tested for. They are often different reports.
Ask for total THC, not only delta-9 THC, especially with federal hemp rules changing on 12 November 2026.
Be wary of any brand that tells you CBD will treat or cure a condition.
A brand that answers clearly, even when the answer is "we don't test for that," is easier to trust than one that dodges.

1. "Can I see the COA for my batch?"

A good answer: a link to a report with a batch or lot number that matches your bottle, the lab's name, and an issue date. A weak answer: one report for a product sold for years, or a PDF with no batch number. Our guide to reading a CBD certificate of analysis walks through each field.

2. "Which lab tested it, and is the lab accredited?"

You want a named, independent lab with an address and an accreditation you can look up. ISO/IEC 17025 is the international standard for the competence, impartiality, and consistent operation of testing labs (ISO). Ask whether you can verify the report with the lab directly, for example through a QR code or report ID on the lab's site.

3. "What was the finished product tested for?"

Potency (how much CBD is in the bottle) is the minimum. Some finished-product reports also include microbiology, and some include the full contaminant set: pesticides, heavy metals, residual solvents, and mycotoxins. Ask which panels were run on the product you will actually use.

4. "What were the raw ingredients tested for?"

Some brands buy CBD distillate or isolate from a supplier and test it separately. That can be where the contaminant panels live. It is a reasonable setup, but ask how the ingredient report connects to your product: which ingredient lot went into your batch, and are the dates close?

We will answer this one for ourselves, since it is a fair question to ask us. Our finished-product COAs from SC Labs (dated May 2025) cover potency and microbials. The full pesticide, heavy metal, residual solvent, and mycotoxin panels are on the reports for our raw ingredients, the CBD distillate and the CBN isolate. All of them are posted on our lab testing page.

5. "How much THC is in it, measured as total THC?"

Federal law has defined hemp by delta-9 THC at not more than 0.3% on a dry weight basis. A change enacted in November 2025 (Section 781) moves that to total THC, including THCa, effective 12 November 2026, with a separate cap of 0.4 mg of total THC per container for final hemp-derived cannabinoid products (7 U.S.C. 1639o). Ask for the total THC figure and the lab's limit of detection. If a brand says "THC-free," ask what that means on the report: "not detected," and at what limit.

This is not legal advice, and as of September 2026 how these rules will be enforced is still developing.

6. "Is it full-spectrum, broad-spectrum, or isolate, and does the report show that?"

These terms describe what else is in the extract besides CBD. A full-spectrum product can contain THC; broad-spectrum and isolate products are made to leave it out. The COA should back up the label: a broad-spectrum product would typically show minor cannabinoids such as CBG or CBC alongside CBD. Our full-spectrum vs. broad-spectrum guide explains the differences.

7. "How much CBD is in one serving, and how did you get that number?"

The bottle total is only half the story. Ask how many servings are in the container and how much CBD is in each. Then check the math against the COA. If a 15 ml bottle claims 1,000 mg and the report shows a result in mg per mL, multiplying by 15 should land close to the label. Our CBD dosage guide covers how people approach serving sizes.

8. "What else is in it?"

Ask for the full ingredient list: the carrier oil, any flavors, preservatives, or essential oils. This matters for allergies, for pets (some ingredients that are fine for people are not fine for animals), and for simply knowing what you are putting on or in your body.

9. "What do you say CBD does?"

Listen for how a brand describes its products. The FDA has sent warning letters to companies selling CBD with claims that it could prevent, diagnose, treat, or cure serious diseases (FDA). A careful brand talks about routines and how people use its products, says research is still early, and suggests you talk with your doctor, especially if you take other medications. See our page on CBD and prescription medication.

10. "Who makes it, and what happens if it isn't right for me?"

Ask who formulates the product, where it is made, and who you can reach with a question. Then ask about returns. A clear return policy, stated before you buy, tells you the brand expects to stand behind the product. Ours is a 30-day money-back guarantee; you can read more about who we are on our about page.

How to judge the answers

Good answers share a few traits. They are specific (a batch number, a lab name, a date). They are complete about limits (what was not tested, and why). And they arrive without pressure. If a brand cannot or will not answer the first question, the rest rarely matter.

FAQ

What is the single most important question to ask a CBD brand?

Ask for the certificate of analysis for your specific batch. It is the one document that lets you check potency, THC, and any contaminant testing against the bottle you are holding.

Should a CBD brand test every batch for pesticides and heavy metals?

Practices vary. Some brands run full contaminant panels on every finished batch; others run them on raw ingredients and test the finished product for potency and microbials. Ask which approach a brand uses, and read the reports to confirm.

What if a brand says its product is "THC-free"?

Ask to see the report. "THC-free" on a label usually corresponds to "not detected" on a COA, which means below the lab's limit of detection. The report should list that limit.

Is it okay to ask a brand these questions by email?

Yes. A brand that sells CBD should expect questions about testing and ingredients, and its answers are part of what you are buying.
