Installs modified apocrine glands that produce synthetic human-compatible pheromones — biochemical signals that influence mood, attraction, trust, and social bonding in nearby people. The pheromones are real neurochemical triggers: oxytocin-promoting compounds that generate feelings of warmth and trust, dopamine-adjacent molecules that enhance perceived attractiveness, and stress-reducing signals that make the user's presence calming. The production can be consciously modulated — increased for social situations, suppressed for privacy. Lacuna Genomics markets it as a 'social enhancement' for corporate networking. Critics call it chemical manipulation of consent. The ethical debate around pheromone modification is one of the most contentious in GLMZ — is biochemically enhanced charisma fundamentally different from wearing nice clothes or having good posture? Most people believe it is. Pheromone users are required to disclose their modification in many social and professional contexts.
