    Summary dose.wiki

    Potency approximately 0.5-0.7× racemic ketamine by weight; larger lines are often required, increasing nasal irritation. Subjectively described as warm, euphoric, and floaty with weaker dissociation than ketamine and a noticeably shorter plateau. Limited human data; virtually all knowledge comes from small animal studies and user reports.
