Short answer: A Certificate of Analysis (COA) is a third-party lab report that confirms the purity and potency of a product. When you read a COA for a 7-hydroxymitragynine (7-OH) product, you should confirm that the potency matches the label, review the heavy metals panel, check for residual solvents, and verify the product passed microbiological testing.
As demand for 7-OH products has exploded, so has the number of companies selling it. Some manufacture in professional facilities and openly publish reports from independent, third-party laboratories. Others offer little more than flashy packaging and bold marketing claims.
That’s why a Certificate of Analysis is one of the most valuable tools a consumer has. A COA isn’t marketing material. It’s a laboratory document prepared by an independent testing facility that verifies the identity, purity, and potency of a product. Learning how to read a 7-OH lab test only takes a few minutes, but it can help you separate transparent brands from companies that could very well have something to hide.
Where to Find the COAs on This Site
There’s no point in providing you with an article about the importance of COAs and how to read them if we can’t show you one, right? So, here’s a handy link to our Lab Reports page, so you can see what we’re talking about.
What Is a 7-OH Certificate of Analysis?
A Certificate of Analysis, commonly called a COA, is an official laboratory report prepared after a product has been independently tested. For 7-hydroxymitragynine products, a complete COA typically evaluates several different categories, including potency, the presence of any heavy metals or residual solvents, microbiology, and batch identification. Taken together, these results tell you whether the product contains the ingredients the label promises and whether it has been screened for common contaminants.
One important point is worth mentioning: A COA is only valuable if it’s recent and batch-specific. Reputable manufacturers test individual production lots, meaning the batch number on the laboratory report should match the batch number printed on your package whenever possible. If you can’t find a batch number or the company only provides a generic lab report from years ago, that should raise questions.
Reading the Potency Profile: Does the Label Match the Lab?
The first section to look at on a COA is the potency profile. This is where the laboratory measures how much 7-hydroxymitragynine, mitragynine, and related kratom alkaloids are actually present in the finished product. For tablets, the result may be expressed as milligrams per tablet or as a percentage of total weight. Either way, the numbers should closely align with what the product label advertises.
If a package claims to contain 20 mg of 7-OH per tablet, the laboratory report should support that claim within accepted manufacturing tolerances. If there’s a substantial difference between the label and the COA, that can pose a couple of problems.
First, consumers deserve to know the exact alkaloid profile of the product they’re purchasing. You paid for it, right? You should get what you were promised. Second, because 7-hydroxymitragynine is a highly active compound, even relatively small differences in potency can significantly change the user experience.
Bottom line: Reliable companies don't ask customers to take their word for it. They let independent laboratories verify every batch.
Scrutinizing the Heavy Metals Panel
Plants naturally absorb minerals from the soil in which they grow. Unfortunately, that soil can sometimes include heavy metals. A quality COA should include testing, at the very least, for these four contaminants: lead, arsenic, cadmium, and mercury.
As you scan this section, keep an eye out for these two terms to determine a product’s pass or fail grade:
ND means Not Detected, indicating the laboratory did not detect the substance above its testing threshold.
LOQ stands for Limit of Quantitation, referring to the lowest concentration the laboratory can reliably measure. Results reported below the LOQ generally indicate extremely small amounts that cannot be accurately quantified.
Neither abbreviation should be alarming by itself. In fact, they’re commonly found on professional laboratory reports. What matters is that the reported values are in compliance with applicable safety standards and that the company makes those results publicly available instead of hiding them.
Residual Solvents and Processing Chemicals
Unlike traditional kratom leaf powder, highly concentrated 7-OH products involve sophisticated extraction and purification processes. Depending on the manufacturing method, solvents may be used during production before being removed from the finished material. That’s why reputable manufacturers perform residual solvent testing. A complete COA may screen for compounds such as ethanol, acetone, hexane, methanol, and isopropyl alcohol.
Don’t worry. While it sounds like you’re gonna need an advanced chemistry degree to slog through this section, it’s actually pretty simple. You’re just looking to see whether the finished product passed the laboratory’s safety specifications in each category. Professional manufacturers invest considerable effort into removing processing chemicals before products ever reach consumers. Independent laboratory testing confirms that those purification steps were successful.
If residual solvent testing isn’t included on a COA, that should raise some red flags about the manufacturer.
Microbiology: The Safety Test Most People Never Think About
Chemical purity is only part of the picture. Botanical products should also be tested for microbiological contamination. Poor harvesting, improper storage, or unsanitary manufacturing conditions can occasionally introduce harmful microorganisms into botanical ingredients. That’s one reason reputable companies routinely screen finished products before they’re released for sale.
A comprehensive microbiology panel often includes testing for Salmonella, Escherichia coli (E. coli), yeast, mold, and total aerobic microbial count. You want confirmation that the product passed these safety tests before it ever reached your hands. It’s another example of why independent laboratory verification matters so much. You can’t see microbial contamination by looking at a tablet … even if you squint.
Don’t Forget to Verify the Laboratory
Who watches the Watchmen?🦉
Okay, comic book reference aside, even an impressive-looking COA deserves a little scrutiny. Ask yourself a few simple questions. Is the testing laboratory clearly identified? Does the report include a testing date? Is there a batch number? Does the report appear complete rather than cropped or partially hidden? Can you access it directly from the company's website or by scanning a QR code on the package?
Trustworthy brands don't make customers hunt for laboratory results. In fact, many (like BARS) make them one of the centerpieces of their quality program because they understand that transparency builds confidence.
What a Missing COA Should Tell You
Sometimes the most revealing laboratory report is the one that doesn’t exist. If a company can't provide current third-party testing, consumers have no reliable way to verify potency, purity, contaminant screening, or manufacturing consistency. That doesn't automatically mean the product is unsafe. It simply means you’re being asked to accept those claims without independent verification. That’s something we think is unacceptable, and we’re guessing you do, too.
Final Thoughts on 7OH COAs
Reading a Certificate of Analysis isn't nearly as intimidating as it first appears. Once you know where to look, you can evaluate a product in just a few minutes. Start by confirming that the potency matches what’s on the label. Review the heavy metals panel. Check that residual solvents were screened. Make sure microbiological testing was performed. Finally, verify that the report comes from an independent laboratory and corresponds to the product you’re actually purchasing.
These simple steps won’t make you an analytical chemist. They will, however, make you a much more informed consumer.
Frequently Asked Questions About 7-OH Certificates of Analysis
What Is a 7-OH Certificate of Analysis?
A 7-OH Certificate of Analysis is an independent laboratory report that verifies a product’s potency, purity, and safety. It typically includes testing for alkaloid content, heavy metals, residual solvents, microbiological contaminants, and batch identification.
Why Is Third-Party Testing Important for 7-OH?
Independent testing helps verify that a product contains what the label claims and has been screened for contaminants. Third-party laboratories provide an additional level of transparency that consumers cannot obtain from marketing materials alone.
What Does “ND” Mean on a COA?
“ND” stands for “Not Detected.” If you see this term on a product’s test results, it indicates that the laboratory did not detect the substance above its established testing threshold.
What Does “LOQ” Mean on a Lab Report?
LOQ stands for “Limit of Quantitation.” It refers to the lowest concentration that a laboratory can reliably measure with confidence. Results below the LOQ are generally present, if at all, only in extremely small amounts.
Should Every Batch Have Its Own COA?
Ideally, yes. Batch-specific testing helps confirm that each production run meets the manufacturer’s quality standards rather than relying on a single historical laboratory report. At the very least, products should be tested regularly and not once in a blue moon.
Can I Trust a Brand That Doesn’t Publish COAs?
Consumers should be cautious when companies refuse to provide current third-party laboratory reports to confirm purity and potency testing. Transparency has become one of the strongest indicators of quality in the modern botanical products industry, particularly with kratom and 7-OH products.
