Before you buy kratom online, ensure that the vendor is reputable and trustworthy. One of the ways you can do this is by asking for a kratom lab test results document, commonly referred to as a Certificate of Analysis (COA).
I remember the first time I got a COA in PDF format, it felt like a secret code. The numbers, charts, tables, and lab names didn’t make sense to me. I’m sure other kratom users felt the same way. At first, it can be confusing, but once you get the hang of it and understand the details, such as the test date and lab names, you can make an informed decision.
Think of kratom lab test results (COA) as a map that will help you get the best kratom experience. It will reveal what’s in the package you just bought. Here is a simple guide on how to read a kratom COA.
What is a Kratom COA and Why Does it Matter
Before we look at the specific details in a kratom COA, it’s important to briefly explain what this document is and why it matters when buying kratom online. Simply put, a certificate of analysis is a laboratory report prepared by laboratory technicians to confirm the ingredients present in the kratom product.
The tests are run on every batch and list any contaminants found, microbiology, like bacteria and alkaloids. It also indicates who tested the batch and when, making it easy for manufacturers to follow up and recall products from the market if they are found to be unfit for human use.
Stay clear of kratom brands that hide their COA or require you to first buy the product to get them. Real Botanicals is one of the few kratom brands that freely sends COAs to their customers before they buy.
Let’s now dive in to look at the specific details contained in a kratom COA.
Start with the Basics: Lab Name and Test Date
A kratom COA is not complete if it doesn’t include the name of the lab where the tests were done and the date. Most of the kratom brands use third-party labs to do the tests, but Real Botanicals takes pride in having its own modern lab in South Carolina. Having its own lab ensures accuracy and protects customers from product tampering during the test process.
Once you know the name of the lab, confirm the date and batch number. The batch number on the COA should match the product batch number printed on the label. Contact the support team immediately if the two don’t match.
Find the Alkaloid Profile Next
Alkaloid profile refers to the specific compounds in the kratom product and their respective concentrations. If you buy regular kratom capsules, the concentration of mitragynine will be higher than 7-hydroxymitragynine and other alkaloids.
Most of the kratom COAs present this information in a table that details the product’s character and potency. If you notice significantly high amounts of one specific alkaloid, like 7oh, that could mean the product is an extract, not a plain kratom leaf. Many COA guides we have come across usually explain how to read the alkaloid profile and what counts as normal levels.
Some brands also provide details of the kratom strains. Check out this guide on different kratom strains to know whether to buy.
Check for Heavy Metals and Pesticides
Good COAs list tests for heavy metals, such as arsenic, mercury, cadmium, and lead. They also list pesticides and solvents that might have been used by the farmers. Any reading above the lab’s specified safe limit should not be ignored.
Trusted kratom vendors publish full panels and clear pass or fail results to cushion customers from contaminated products. In particular, Real Botanicals provides heavy metal results for batches so buyers can see the exact numbers before placing orders. That level of detail and transparency is one of the many highlights that give this kratom brand an upper hand.
Look for Microbiological Testing Results
Microbiology tests are done to confirm that the kratom product doesn’t contain any mold or bacteria. When reading a kratom lab test results COA, look for terms like E.coli, Salmonella, total aerobic plate count, yeast, and mold counts.
A credible COA shows these results and lists acceptable limits. Avoid products from batches that exceed the limits or have high colony counts.
Test Methods and Units of Measure
In addition to the location of the lab where the tests were conducted, the COA should also indicate the test methods used, such as UHPLC, HPLC, and GC-MS. Also, check the units. Alkaloid content is usually indicated as a percentage or mg/g ratio and heavy metals as ppm or ppb. Contact the brand if these units are missing.
How to Differentiate Leaf From Extracts on a COA
A kratom leaf will show a balanced alkaloid profile. Extracts often exhibit unusually high levels of a single alkaloid or high total alkaloid content. If the numbers appear off compared to normal leaf ranges, that may shows the product is concentrated or altered.
Knowing how to read a kratom lab test result COA correctly is your best best for safe kratom use and getting value for money, especially if you intend to buy kratom online in wholesale. It informs you about the product’s contents, how it was tested, and whether it has passed safety checks. Don’t shy away from contacting the support team for clarification if any detail is unclear.
