alpha-PHP is an extremely potent stimulant with a high addiction liability and significant risks of paranoia, anxiety, and psychosis. It is structurally related to alpha-PVP but with a longer alkyl chain. Users report intense compulsive redosing, especially when vaporized. The substance can produce severe cardiovascular strain, hyperthermia, and extended psychotic episodes. Due to its long half-life, psychotic symptoms may persist for days.
