Experience

Primary effects

Produces a state of dissociative anesthesia, causing mild euphoria, numbness, and motor impairment.
Induces a pleasant, interesting, and anxiolytic dissociative experience with mood-lift and analgesia.

Peak character

A slightly euphoric dissociation where one is functional but misaligned with reality, fostering introspection and concentration.
Visual reality is distorted and alien, yet anxiolytic properties prevent it from being threatening; bodily insensitivity makes movement feel smooth and floating.

Negatives / side effects

Higher doses are capable of producing internal hallucinations, warranting due care and attention.
As a research chemical, its long-term effects are unknown; combinations with other substances can be problematic.

Aftereffects / comedown

Difficulty sleeping at normal times without aid, even hours after peak effects.
The night after consumption may be disturbed with vivid dreams, followed by a positive afterglow lasting several days.
