Subjective Effects
Legacy content. A statistically backed ontology from Mindstate Design Labs is coming soon.
Very little is documented about the effects of this compound. Available reports describe a psychedelic-type experience combining euphoria, altered perception, and both mental and physical stimulation, with visual changes and a softening of the sense of self.
Physical
Stimulation, restlessness, and muscle tension are reported, along with autonomic changes such as pupil dilation, sweating or chills, decreased appetite, and difficulty sleeping.
Cognitive
The headspace is described as euphoric and empathetic, with a sense of insight and ego softening, though confusion has also been reported.
Emotional
Visual
Visual effects are reported both with the eyes closed and with the eyes open, alongside brightened colors.
