Questions about PharmLabs and Gold Standard Analytics
Is Gold Standard Analytics a PharmLabs alternative for kratom testing?
Yes for published prices, online ordering and a public certificate library on kratom potency, metals, microbes and pesticides. If you need mitragynine pseudoindoxyl or MGM-15 reported under an accredited scope, PharmLabs names both and Gold Standard does not currently report them.
How much does PharmLabs charge for kratom testing?
PharmLabs prices are behind an account login; no numeric kratom fee is public. Gold Standard charges $199 for the seven-alkaloid profile, $149 for metals and $89 for microbiology.

Yes. Its PJLA certificate (85368 / L25-933-R1, revised January 14, 2026) expires February 29, 2028 and names six kratom targets under HPLC SOP-044. Gold Standard is not accredited and operates to ISO/IEC 17025 expectations; we state that plainly rather than imply otherwise.

Mitragynine, 7-hydroxymitragynine, dihydro-7-OH/MGM-15, mitragynine pseudoindoxyl, speciogynine and speciociliatine by HPLC. Gold Standard reports mitragynine, 7-hydroxymitragynine, speciogynine, speciociliatine and paynantheine, with low-level 7-OH by LC-MS/MS on the same accession.
