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.[1]

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.[2]


5-IAI was an attempt to make a non-neurotoxic analog of PIA.
