    Summary TheDrug.Wiki TripSit PsychonautWiki

    3,4-CTMP is approximately seven times more potent than methylphenidate and has a significantly longer duration of 6-18 hours. A critical safety concern is its agonist activity at 5-HT2B receptors, which can cause pulmonary hypertension and heart valve fibrosis with repeated use. Insufflation is strongly discouraged as the substance has low water solubility, is extremely caustic to nasal tissues, and has poor absorption leading to delayed onset that increases overdose risk. Users must use precise milligram scales due to the extremely low active doses. The very long onset (1-2 hours) and extended duration require careful dose timing to avoid unwanted sleep disruption and accidental overdoses from premature redosing.
