On this page you will find certificates of analysis from an independent testing laboratory in Indonesia, Laboratorium Penguji LP-024-IDN, part of the Sucofindo group. Each one was issued for a powder sample taken from a lot our supplier sent in for testing, and each is a supplier lot report that we have assigned to the strain it is filed under. Every report lists moisture, particle size, mitragynine content, four metals and two microbiology checks, with the limit printed beside each result.
Please read these as a record of one sample on one date. They describe the lot that was tested and do not promise that a future batch will give the same numbers. Client names, reference numbers, verification codes and the lab’s sample-type wording have been masked on our copies; the results, limits, methods and dates are exactly as the lab printed them.

White Maeng Da
E37078/BNBPATIssued August 19, 2026Report E37078 covers a sample that reached the lab on August 10 and was analysed through August 18. Most metal rows on it carry a “<” sign, but arsenic is different: the lab printed an actual number, 0.1790 mg/kg, which is roughly 12% of the 1.5 mg/kg ceiling shown beside it. Mitragynine was measured at 1.86%.
Sample received: August 10, 2026. Analysis window: August 10, 2026 – August 18, 2026.

Quick pointers for reading the tables
- The right-hand column of each table repeats the limit printed on the certificate. A result that sits inside that limit is a pass on that line.
- A “<” sign means the lab could only say the amount was below the smallest figure its method can report.
- Test methods and units appear on the PDF itself: HPLC for mitragynine, ICP and AAS for the metals, British Pharmacopoeia procedures for the microbiology lines.
- Each PDF is a supplier lot report: the lot was submitted to the laboratory by our supplier and we have assigned it to the strain it is filed under. The laboratory’s report itself does not name a retail strain, and the sample-type wording is masked on our copies.
For the longer explanation, including why the report number and dates matter, see Kratom Testing and the Certificate of Analysis, Line by Line.
