Dosage & Duration
Dosage
Doses are population estimates that vary widely between individuals.
Duration
Subjective Effects
Legacy content. A statistically backed ontology from Mindstate Design Labs is coming soon.
Effects vary widely by individual, dose, and context.
Physical
Cognitive
The head space of MXP is often described as particularly clear headed even at heavy dosages. It is far more controllable, less disorientating and confusing at dosages of equal subjective intensity to that of MXE, DXM and Ketamine.
Visual
Hallucinatory States
Auditory
The auditory effects of MXP are common in their occurrence but unlike other more commonly used dissociatives, they are unlikely to suppress or distort auditory input.
Pharmacology
Interactions
An unlisted combination is an unknown one, not a safe one. Check a dedicated combination chart before mixing.
Tolerance
Harm Potential
Addiction & Dependence
Psychological
Addictive potential has not been established, though the substance is categorized as habit-forming. Strong tolerance development may contribute to compulsive redosing patterns.
Toxicity
Acute intoxication can produce hypertension and tachycardia; elevated blood pressure has been observed during use, along with peripheral vasoconstriction.
Psychosis Risk
Psychotic episodes have been reported, including at least one case associated with violent behavior resulting in a murder in June 2014. Acute intoxication has been reported to produce confusion.
Seizure Risk
Seizures have been reported at high doses according to user reports, warranting additional caution with dosing.
