Metyleenidioksifenmetratsiini

MDPM is an extremely novel substance with virtually no human pharmacological data. It acts as a strong CYP2D6 inhibitor and moderate CYP3A4/CYP1A2 inhibitor, creating significant drug-drug interaction risks when combined with medications or substances metabolized by these enzymes. Often appears as a synthetic impurity in MDMA manufacture. Confirm identity with spectroscopy before use. Use professional reagent testing, employ allergy tests, and practice incremental dosing.
