Quick reference
Duration
Experience
Primary effects
- Induces a psychedelic headspace with enhanced colors and drifting focus, similar to psilocybin.
- Causes visual distortions such as diffraction, slight morphing, tracers, and over-currents.
- Results in pupil dilation and can feel surprisingly potent even at low doses.
Peak character
- Headspace can be strong and immersive, leading to a profound, restful, or even sleep-inducing state.
Negatives / side effects
- Can lead to overwhelming '++++' experiences at doses under 20mg; caution and standard safety measures are essential.
- Combining with fatigue or hangover can amplify the need for sleep, potentially cutting short the experience.
Aftereffects / comedown
- Short duration, leading to a quick return to baseline after the peak effects subside.
- Can induce deep sleep or dozing during the experience, followed by feeling well-awake afterwards.
Reference dosage
Reference ranges from third-party harm-reduction databases. Individual response varies enormously — start lower than you think.
| threshold | 2.5mg+ |
| light | 3mg+ |
| common | 8mg+ |
| strong | 25mg+ |
Reagent testing
| Ehrlich | Purple/violet (strong) |
| Hofmann | Blue → green |
| Mecke | Blue → green |
Adulterant detection: Ehrlich is highly reliable for this tryptamine. Absence of purple is a clear red flag.
Synthetic psilocybin analogue — one of the cleanest Ehrlich reactions in the tryptamine family.
