4-כלוריד-PPP
4-Cl-PPP (4-chloro-α-pyrrolidinopropiophenone) is an obscure designer stimulant with minimal human data beyond forum reports. Para-chloro amphetamine analogues have shown serotonergic neurotoxicity in animal studies, raising concerns about potential long-term risks. Users report rapid tolerance formation (within 1-2 days), brief euphoria followed by pronounced compulsion to redose, severe insomnia, and an unpleasant crash. The compound is reportedly very caustic to nasal tissue when insufflated. Similar to α-PVP, users report auditory misperceptions and risk of psychotic features with extended use or sleep deprivation.
