Laboratory tests KRATOM
When choosing a supplier, it is always essential for us quality control - initially on paper and then in practice with „own eyes“. If a potential supplier is unable to deliver current lab tests with his name in the original file, so we're not even dealing with him anymore. After importing kratom from Indonesia, we test the powder ourselves in Czech laboratories. You can see the sponsor's name on the lab tests Czech Wholesale Botanicals s.r.o. - it was my second Czech company, through which I sold kratom wholesale via regulation and we had the tests done at CWB Ltd. through VAT deduction.
Kratom is currently in the „grey zone“ according to Austrian legislation and can only be sold and recognized as a collector's product. But that does not change the fact that even collector's pieces should have some quality control. Be careful, however, of the provenance of the test itself. We respect only laboratory tests done in the USA, Czech Republic or other developed Western countries - we especially like the laboratory MURRAY-BROWN LABORATORIES, INC. Lab tests from Indonesia (or similar country) are usually not legitimate - most of these labs are not trustworthy.
Several aspects are important to observe in laboratory tests. The main ones include the alkaloid content - Mitragynine, 7-Hydroxymitragynine and a few others. Other important factors include bacterial, heavy metal or fungal content. Since this is a collector's item, we are primarily interested in this because of the collectible value of the item.
As far as the content of the main alkaloids mentioned is concerned, it is mainly mitragynine (MIT for short) that is important for determining the collection value. The mitragynine content varies from kratom to kratom - primarily according to the age of the tree from which the leaf comes and then also according to the processing of the leaf by the farmer. However, I would like to point out that kratom with a lower content of mitragynine can also have a collecting value if it contains other alkaloids in a higher proportion. Unfortunately, we do not yet have the possibility to measure all active alkaloids found in kratom and therefore I recommend looking mainly at the numbers determining the content of mitragynine. During fermentation, mitragynine is converted into other important alkaloids - currently we are talking about 7-Hydroxymitragynine and Mitragynine pseudoindoxyl.
According to our experience, 1% to 2% MITRAGYNINE is found in quality kratom for collecting purposes. The former standard according to older sources was 0,5% - 1,5% MIT. If someone advertises kratom with MIT greater than 2%, you need to beware because it is usually a poor testing method, fake tests (paid numbers) or kratom enriched with extract (for testing only, usually not the final product!). In darker colours, especially those that have undergone fermentation, this number tends to be lower. As for the lighter kratoms - white and green, we recommend buying only those with a mitragynine content of at least 1.2%. ♥
Upon request, we will provide a preview of the original files of all laboratory tests, possibly together with invoices from our suppliers whose name matches the sponsor of the laboratory test. We only provide full quality files to the Czech inspection authorities on request. We have the exclusive right of commercial use for all laboratory tests on our website that have been supplied for the purchase of physical goods, as we see fit.
All laboratory tests for our kratom can be found here in the individual sections divided by supplier:

On the right are results of our own laboratory tests of three homogenized powders according to colour - white, green and red. We took an individual color from each supplier and mixed together in a 1:1:1:1 ratio. In this mix was powder from all suppliers at the time (Maeng Da, Borneo, Kapuas and Kalimantan sources).
