    Product Description

    5α-Androst-16-en-3-one is a mammalian pheromone released as a volatile chemical cue in boar saliva to facilitate social and sexual interactions.1 It has been used to prime sexual behavior of sows in estrus for mating or artificial insemination. 5α-androst-16-en-3-one is also found in human sweat and urine and has been used to study receptor-mediated odorant detection and the genetic basis for anosmias.2

    WARNING This product is not for human or veterinary use.
