alpha-PEP (alpha-Pyrrolidinoenanthophenone)
alpha-PEP is a long-chain pyrrolidinophenone cathinone, a higher homologue of alpha-PVP/alpha-PHP that surfaced on grey markets as scheduling pressure pushed vendors toward ever-longer alkyl chains. It is presumed to be a potent norepinephrine-dopamine reuptake inhibitor with high addiction risk and virtually no human data.
01 Overview
alpha-PEP (alpha-pyrrolidinoheptaphenone) extends the alkyl chain of the pyrrolidinophenone series one carbon beyond alpha-PHP. It is sold as a designer cathinone stimulant for insufflation or vaporisation.
No human pharmacology studies exist. All risk assessment is read-across from alpha-PVP/alpha-PHP, which reliably predict potent, compulsive stimulation and severe sympathomimetic and psychiatric toxicity.
02 Mechanism
Presumed potent norepinephrine-dopamine reuptake inhibitor of the pyrrolidinophenone class.
03 Dosing
| Tier | Dose | Route | Notes |
|---|---|---|---|
| Common (approximate, anecdotal) | 5–15 mg | Insufflated | No validated dosing; alpha-PVP-like caution advised. |
04 Effects
| Effect | Magnitude | Evidence | |
|---|---|---|---|
| Potent stimulationExpected intense energy and euphoria by class analogy; unverified. | Presumed strong | Unconfirmed | |
| Compulsive redosingCharacteristic of pyrrolidinophenones. | Presumed strong | Unconfirmed |
05 Side effects
| Effect | Severity | Frequency | Evidence | Countermeasures |
|---|---|---|---|---|
| Sympathomimetic toxicityTachycardia, hypertension, arrhythmia and hyperthermia risk by analogy to alpha-PVP. | Severe | Unknown | Unconfirmed | |
| Psychosis and agitationParanoia, hallucinations and severe insomnia expected with binges. | Severe | Unknown | Unconfirmed |
