Use and effects

TFMPP is rarely used by itself. In fact, TFMPP reduces locomotor activity and produces aversive effects in animals rather than self-administration, which may explain the decision of the DEA not to permanently make TFMPP a controlled substance. More commonly, TFMPP is co-administered with BZP, which acts as a norepinephrine and dopamine releasing agent. Due to the serotonin agonist effects and increase in serotonin, norepinephrine, and dopamine levels produced by the BZP/TFMPP combination, this mixture of drugs produces effects which crudely mimic those of

, especially the headache, nausea, and hangover. However, it is difficult to say how many of these side effects are produced by TFMPP itself, as it has rarely been marketed without BZP also being present, and all of the side effects mentioned are also produced by BZP (which has been sold as a single drug). Studies into other related piperazine drugs such as mCPP suggest that certain side effects such as
