Transparency we are happy to share.
Our kratom is regularly analyzed by a specialized laboratory for botanical raw materials — for heavy metals and for microbiological parameters. You can view and download the original certificates on this page.
Why we have it tested
Kratom is a botanical raw material. Cultivation, drying, transport and storage influence its characteristics — this applies to leaf material just as to any other botanical raw material. That is why we have it analyzed regularly and publish the results. Anyone processing or archiving material should know what they are dealing with.
What is tested
The analyses follow established methods of botanical raw material analysis and cover two areas:
Microbiological analysis
- Total aerobic microbial count
- Yeasts and molds
- Coliforms
- E. coli
- Salmonella
- Staphylococcus aureus
Heavy metal analysis
- Arsenic
- Cadmium
- Lead
- Mercury
- Manganese

Mikrobiologische Analyse
Our Partner Lab
Wonderland Labs in Vista, California, is an analytical laboratory specializing in botanical raw materials with many years of experience with Mitragyna speciosa. We work with this lab because its analytical methods for this material are well established.
These analyses characterize the botanical raw material. They make no statement about suitability for consumption — our products are not intended for consumption and are supplied exclusively as dye, collector’s or research material.
Diese Analysen charakterisieren den botanischen Rohstoff. Sie sind keine Aussage über eine Eignung zum Verzehr - unsere Produkte sind nicht zum Verzehr bestimmt und werden ausschließlich als Farb-, Sammel- oder Forschungsmaterial abgegeben.
Frequently Asked Questions
What does "CFU/g" mean?
Colony Forming Units per gram: meaning how many living microorganisms are contained per gram of sample. The lower the number, the purer the sample.
What is "ppb"?
Parts per billion: one part in a billion. Concentrations of heavy metals are measured in this unit because very small quantities are detected.
How often are tests performed?
Our batches are regularly analyzed. You can find the current results on this page.
