3,4-CTMP3,4-Dichloromethylphenidate (also known by the incorrectly abbreviated name 3,4-CTMP) is a stimulant substance of the phenidate class.It is a structural analog of methylphenidate (Ritalin). The two substances have similar pharmacological profiles but different subjective effects.It is approximately seven times more potent than methylphenidate in animal studies, but likely has weaker reinforcing effects due to its slower onset of action.According to anecdotal reports, the active dose of 3,4-CTMP is approximately 10 times lower than the dose of methylphenidate to achieve a similar effect. 3,4-CTMP has a duration of 6 to 18 hours rather than the 4 to 6 hour duration found with methylphenidate.3,4-CTMP has an extremely short history of human recreational use and has yet to be documented being sold on the streets. It is available for sale as grey market research chemical by online vendors.3,4-CTMP acts as a dopamine and norepinephrine reuptake inhibitor, meaning it effectively boosts the levels of dopamine and norepinephrine neurotransmitters in the brain by binding to and partially blocking the transporter proteins that normally remove those monoamines from the synaptic cleft.Physical effects Stimulation 3,4-CTMP is moderately to highly stimulating. The stimulation present is weaker than methamphetamine, cocaine, and amphetamine. It is stronger than caffeine and similar in strength to methylphenidate.
