Primary effects
- Causes a dissociative state with altered sensory input, described as slightly distant and distinct.
- Induces a warm, flushed sensation with tingling numbness, and a contented, rounded disposition likened to opioid effects.
- Can create a peculiar heady quality and potential for increased libido.
Peak character
- Dissociation described as solid and not overly dramatic, allowing full control of faculties.
- Mood is contented and pleasant, despite an air of fatigue.
- A "heady" presence is noted, not a headache, which might develop.
Negatives / side effects
- Has a reputation for causing higher rates of mania and psychosis, similar to PCP.
- Reports suggest more physical side effects like muscle soreness and flu-like symptoms, potentially indicating higher toxicity at increased doses.
- Risk of bladder damage is a concern, analogous to other dissociatives like ketamine. Dosage is critical, with even 5mg considered high for a first-time user.
Aftereffects / comedown
- Mild afterglow with a dreamy headspace and general contentment.
- Lingering balmy feeling and a slight headache that can persist until the next morning.
- Can provide a sense of reset, similar to other dissociatives and psychedelics.
