Summary
Alpha-PiHP is a potent synthetic cathinone and positional isomer of alpha-PHP, with significantly higher potency than cocaine and methamphetamine as a dopamine transporter inhibitor. It typically appears as white to off-white powder and is consumed orally, insufflated, or vaporized. The substance has been linked to fatal intoxications and severe adverse effects including cardiac complications, psychosis, and seizures. Users commonly report extremely unpleasant body load at higher doses, severe paranoia, and overwhelming compulsion to redose. Harm reduction practices and accurate dosing are critical due to the rapid onset and high overdose risk, especially with vaporization.
