# How to Read Our Lab Report: The Risachi COA, Explained Line by Line
> A certificate of analysis (COA) is a third-party lab report verifying what is actually inside a supplement. Risachi publishes the COA for every batch. Reading one takes about two minutes once you know the three checks: the lab's name and accreditation (it must not be the manufacturer), the potency panel (does measured CBN and CBG match the label?), and the THC line (Risachi tests non-detectable). The same checklist exposes weak COAs from any brand: missing lab names, potency-only panels, expired reports, or results that don't match the product being sold.

A certificate of analysis (COA) is a report from an independent laboratory stating what a product actually contains. It is the only document in the supplement world that verifies a label instead of repeating it. Risachi publishes ours for every batch at [risachihealth.com/coa-sleep-gummies.pdf](/coa-sleep-gummies.pdf) — and this guide walks through it line by line, because a lab report you can't read is just decoration.

## Why a Lab Report Matters More Than a Label

Supplements are not pre-approved by any agency before sale. The label is a claim; the COA is a measurement. The gap between those two can be enormous: a 2023 JAMA analysis found 22 of 25 melatonin gummies sold in the US contained between 74% and 347% of their labeled dose, and one contained no melatonin at all — it contained CBD instead. That study is the entire argument for third-party testing in one sentence.

## Check 1: Who Ran the Test

The first thing to find on any COA is the laboratory's name and address, usually at the top of the report. The lab must be a third party — independent of the brand and the manufacturer. In-house test results are better than nothing, but they are the manufacturer grading its own homework.

- The lab is named, with an address and contact information
- The lab is not the brand or its manufacturer
- The report carries a date — recent enough to plausibly cover the batch on sale

## Check 2: The Potency Panel

The heart of the COA is the potency table: measured milligrams of each cannabinoid, per gummy or per serving. On the Risachi COA, the two lines that matter are CBN and CBG. The label says 20mg CBN and 15mg CBG per serving; the potency panel is where an independent lab confirms the gummies actually deliver it. Small variances are normal in manufacturing — a measured value within roughly 10% of the label is the widely used benchmark. What you should never see is a large gap, or a potency line for an ingredient the label doesn't mention.

## Check 3: The THC Line

Risachi gummies are made with hemp-derived CBN and CBG, and every batch tests non-detectable for THC — on the COA this reads as "ND." That is a stricter result than the 0.3% federal hemp threshold: not merely under the legal limit, but below what the instrument can detect at all.

One honest caveat we make everywhere, including here: no supplement brand can promise you a drug-test outcome, because tests, thresholds, and individual factors vary. What a COA gives you is the measured input — non-detectable THC in the product. If your career depends on a test, read the COA and talk to your employer or doctor before taking anything.

## Red Flags on Any Brand's COA

The same three checks expose a weak lab report from any company. Walk away from a sleep gummy when you see:

1. No COA at all — you are being asked to take the label on faith.
2. No lab name, or the "lab" is the manufacturer itself.
3. A potency-only report with no THC line on a hemp product.
4. An old report being reused across batches, or a COA for a different product than the one being sold.
5. Measured potency that misses the label by a wide margin — in either direction.

We built our buying guide around exactly these checks: [How to Choose a Sleep Gummy](/journal/how-to-choose-a-sleep-gummy).

## Why We Publish It

Publishing a COA costs a brand nothing if the product matches its label — which is precisely why the brands that don't publish one are telling you something. Transparency is cheap when you have nothing to hide. Every Risachi batch gets tested, every report gets published, and if you ever want the COA for a specific batch number, email [support@risachihealth.com](mailto:support@risachihealth.com) and we'll send it.
