Experience

Primary effects

This psychedelic is also a substituted amphetamine, known for stimulation and an intense body high.
Induces a moderate headspace, increased sexual appetite, and blurred/fuzzy vision.

Peak character

Headspace is mellow.
Significant effect on libido and sex drive.

Negatives / side effects

Can cause severe physical discomfort, including tight-chestedness, clamminess, trembling hands, and elevated blood pressure and heart rate.
Body load and discomfort can be intense enough to hinder mental exploration or enjoyment of other effects.
Cardiovascular strain is a significant risk, potentially linked to its amphetamine properties. High doses have caused hospitalizations in the past.

Aftereffects / comedown

Unpleasantness subsides, leaving a hazy, slightly sleepy feel and general body awareness.
Can result in exhaustion, both mentally and physically, requiring extended rest.
Mild lingering headspace and body tactility post-peak; normal physiological parameters eventually return.

Adulterant detection: Amphetamine-class phenethylamine. Rapid black Marquis would indicate non-DOM amphetamine adulterant.

Very potent; active in microgram doses. Testing is critical — even small impurities are significant at these doses.
