Certificates you can read for yourself
The full certificates sit on our Lab Reports page: six of them, one per strain, each a supplier lot report issued by an independent laboratory for a single powder sample. Every certificate lists the measured mitragynine percentage, moisture, particle size, four heavy metals (lead, cadmium, arsenic and mercury) and two microbiology checks (E. coli and salmonella), printed next to the limit the lab applied. Each one can be downloaded as a PDF.
Treat each certificate as a snapshot: it describes the sample that went to the lab on that date, and a later lot may give slightly different figures. If the strain you bought is not on the page yet, email the batch number from your bag to support@kratomcanada.com and we will tell you what we have on file for it.
