Manufacturer product information describes 5-BPDi as a research chemical in the stimulant family1. It is an analogue of a-PHP with a reportedly similar effect profile, although some users describe lighter effects and less compulsion to redose. Reported use remains limited, so these distinctions are based on limited user accounts.
