MGM-15, also known as dihydro-7-hydroxy mitragynine, DH-7OH-MIT is an opioid drug which is a semi-synthetic derivative of 7-hydroxymitragynine, a natural product derived from the Southeast Asian tree kratom. MGM-15 was first reported in 2014. It is the 1,2-dihydro derivative of 7-hydroxymitragynine and shows higher potency as an agonist of the μ-opioid receptor and δ-opioid receptor compared to 7-hydroxymitragynine itself. MGM-15 has been sold as a designer drug since early 2025, initially in the US.
