The 7-hydroxymitragynine (7OH) market is growing quickly. It seems like new brands are launching every day, with products featuring the popular kratom alkaloids mitragynine and 7-hydroxy. But underneath that growth lies an uncomfortable truth: This space is largely unregulated, and without the right information, it’s difficult to know for certain what you’re putting in your body when you take one of these products.
That's not a reason to walk away from 7OH, but it is a good reason to get informed.
Lab testing is the single most important factor that separates trustworthy brands from questionable ones. Specifically, we’re talking about third-party lab testing with results that are readily available for the public to view.
This guide will show you exactly what to look for in these lab tests and why it matters for your health … and your overall 7-hydroxy experience.
Quick Hits
-
Because 7-OH isn’t regulated, it’s important to be able to verify a product’s purity and potency with a lab test
-
Testing should be conducted by an independent third-party laboratory
-
The report from this testing is called a Certificate of Analysis (COA)
-
Any reputable brand will make their COAs available to customers
The Wild West of Alkaloids: Why Regulation Makes Third-Party Testing Non-Negotiable
The FDA does not currently regulate 7-hydroxymitragynine as a pharmaceutical drug. So, there’s no federal agency requiring manufacturers to test their products before they reach the shelves. That means no mandated potency verification, no required screening for contaminants, and no standardized labeling requirements. So, as a customer, all you have is the word of the brand from whom you are purchasing … unless there is a third-party lab test to back up their claims.
Responsible companies voluntarily submit their kratom powders or 7OH tablets to accredited, independent laboratories for testing. Third-party testing matters precisely because it removes any conflict of interest: A lab with no financial stake in your product has every reason to report exactly what it finds.
When a brand publishes its 7OH lab results openly and keeps those reports current, it’s not just a marketing ploy. It’s a commitment to transparency and accountability in a marketplace where those things are optional. If a brand doesn’t share their lab reports, it means they either never bothered to have their products tested or they have something to hide. In either case, your safety is at risk with their products.
Reading a COA (Certificate of Analysis): What to Look For
A Certificate of Analysis (COA) is the report issued by a third-party laboratory after testing a product. Any reputable 7-OH brand will take care to display their COAs directly on their website, where they can be easily accessed by customers. When you open a COA, here's what you should look for …
Product and Batch Information
Toward the top of the document, you’ll find information on the specific product that was tested, as well as its batch number. Make sure the name matches the product you’re researching. Also, importantly, you’ll find the date of the test. Make sure your product has been tested recently. And if the brand has been around a while, look for multiple reports to make sure they do this kind of clinical research and testing regularly.
Potency and Alkaloid Content
This section tells you how much of the mitragynine metabolite, 7-hydroxy, is actually in the product. It also tells you the content of other alkaloids present, such as kratom mitragynine and mitragynine pseudoindoxyl. The amounts of these alkaloids are displayed in milligrams per gram or as a percentage. On the report, you should be able to cross-reference this number with what’s listed on the product label. If the COA shows significantly fewer milligrams than what’s advertised, that should be a red flag. If the report shows more than expected without further explanation, that is worth questioning, too. Accuracy means everything, especially when you’re dealing with a highly potent compound.
Heavy Metals Panel
Kratom is a plant (specifically, mitragyna speciosa) and, as such, it absorbs chemical compounds from the soil surrounding the plant. These can potentially include heavy metals, such as lead, arsenic, cadmium, and mercury. A complete COA will include a heavy metals panel with results measured in parts per million (ppm) or parts per billion (ppb). Look for results that fall below USP (United States Pharmacopeia) or California Prop 65 limits. Any reputable brand testing for kratom safety standards will include this panel on their displayed reports.
Residual Solvents
During the extraction process used to isolate 7-OH, chemical solvents are often employed. A thorough COA will confirm that these solvents have been fully filtered out of the final product and are present only at trace levels (well below established safety thresholds). If a COA doesn't include a residual solvents panel, that could be a red flag.
Microbiology
Some Certificates of Analysis also include testing for microbes, such as yeast, mold, E. coli, and Salmonella. While this kind of testing isn’t universal, the presence of a microbial panel signals a higher level of diligence and is especially relevant if you’re consuming your 7-OH sublingually or in a dissolvable format.
Synthetic vs. Natural Extraction: Setting the Record Straight on This Mitragynine Metabolite
One of the most persistent misconceptions about 7-OH products is the idea that all extracted 7-hydroxymitragynine is “synthetic.” As you’ll see, that isn’t necessarily the case …
Naturally extracted 7-OH is isolated directly from kratom leaf material using chemical processes, which typically involve solvent-based extraction followed by a purification step. The compound itself is identical to what exists in the plant, only it’s been concentrated and separated from the other alkaloids. Done correctly, with proper purification and third-party verification, this is how pure 7-hydroxymitragynine is produced responsibly.
Synthesized 7-OH, on the other hand, is engineered in a laboratory without starting from kratom plant material. While synthetic production isn’t inherently dangerous, it requires rigorous testing of its own … and less scrupulous operations may cut corners when it comes to purity verification.
The important takeaway is that the method of isolation matters less than the verification of what's in the final product. Whether natural extraction or synthesis is used, a full COA with potency and contaminant panels is the only way to confirm that you’re getting what you paid for. Any brand that makes vague claims about “natural” sourcing without supporting those claims with a published, third-party lab report simply shouldn’t be trusted. Remember, your health and well-being rely on your product’s purity and accuracy in terms of serving size.
Our Commitment to Quality: Why BARS Does It Differently
At BARS, we believe that customer trust begins with transparency. Every one of our 7OH tablets is submitted to accredited third-party laboratories for rigorous testing. Our testing protocols cover all bases: alkaloid potency, heavy metals, residual solvents, and microbiology.
We publish our COAs by lot number, so that you can verify exactly what was in the batch you purchased and not a batch from two years ago. We don’t cut corners on sourcing, and we don't make label claims that we can’t back up with documentation.
In a market where none of this is required, we require it of ourselves. We believe that customers deserve to know what they’re getting in each and every tab we sell, and we can only earn their confidence when our 7OH lab results are real, recent, and readily available. So, we encourage you to browse our BARS collection and look for the COA link on every product page.
The Bottom Line on Testing for 7-Hydroxy and Kratom Products
7-Hydroxy products have a lot to offer customers, in terms of effects and benefits. But having a critical eye to differentiate responsible brands from shady ones is key. Third-party lab tests are the best way to tell if the 7-OH product you’re purchasing is as pure and potent as promised, which is why testing is a high priority for our brand. We wish you happiness and good health as you explore the world of 7-hydroxy!
