PRL-8-53 is a nootropic research chemical derived from benzoic acid and phenylmethylamine that has been shown to act hypermnesic in humans; it was first synthesized by medical chemistry professor Nikolaus Hansl at Creighton University in the 1970s as part of his work on amino ethyl meta benzoic acid esters. Lab tests have revealed Hypermnesics are capable of enhancing cognition and memory. PRL is being widely touted as a tool that aids in learning and memory retention.
