Androstadienone: The Bonding Molecule Each 10ml bottle contains a single perfumery molecule known simply as A1. In research circles it's often referred to as the "love molecule". Just one naturally-occurring ingredient at 2mg/10ml or 10mg/10ml concentrations. While worn primarily by men; women can also wear A1 (generally in smaller dosages) for relaxing self effects and increased emotional depth.
