Para-Iodoamphetamine

"para"-Iodoamphetamine (PIA), also known as 4-iodoamphetamine (4-IA), is a research chemical of the phenethylamine and amphetamine chemical classes.
It acts as a selective serotonin releasing agent and is also a MAOI.
PIA is rumored to be a serotonergic neurotoxin on the account of that being reported to be the case for "para"-chloroamphetamine.
However, PIA is a much weaker 5-HT neurotoxin than is the case for PCA.
Analogs.
5-IAI was an attempt to make a non-neurotoxic analog of PIA.
