ІК-26
Methiodone replaces methadone's ketone with a sulfone bioisostere, preserving μ-agonism but with variable potency reported at approximately 0.5-1.0× methadone. Users describe a slow, maintenance-like warmth rather than sharp euphoria. The caustic powder is best administered in oral capsules or dilute solutions. Accumulates over successive days; wait at least 12 hours before redosing. QT prolongation risk is assumed comparable to methadone; ECG monitoring is advised for chronic use.
