Brief Description
Dihydro-7-hydroxy mitragynine (“MGM-15”) is synthetic derivative of 7-hydroxy mitragynine. It is structurally similar to known kratom alkaloids and is the primary component in products being sold as “MGM-15”.1 Analysis of dihydro-7-hydroxy mitragynine is challenging due to the analytical conversion of dihydro-7-hydroxy mitragynine to mitragynine during GC-MS analysis. Dihydro-7-hydroxy mitragynine was first identified by our laboratory in September 2025 and confirmed after acquiring standard reference material.
