SC Labs vs Gold Standard Analytics for kratom testing
SC Labs routes kratom to its Warren, Michigan laboratory, whose PJLA ISO/IEC 17025 scope (137692 / L26-743, issued August 2026) explicitly lists kratom HPLC method 66139. It advertises a ten-alkaloid panel plus metals, microbes, mycotoxins, pesticides, solvents, foreign matter and moisture at 3–5 days, priced by quote. Its landing page names only mitragynine and 7-OH of the ten. For a named target list at a published price with every certificate public, Gold Standard Analytics is the alternative.
