Summary
Very limited human data. Reports highlight a steep doseβresponse curve, mild visuals versus cognitive effects, rare bladder discomfort, and pronounced inter-individual variabilityβcareful titration is essential.
Perspectives
“This drug is okay at best. The last time I tried it at 30 mg I barely had threshold effects, but the urinary symptoms presented in full force.”

Acute tolerance appears to build rapidly after one session and decays over roughly 1β2 weeks, consistent with broad psychedelic patterns; exact kinetics for 2CβiP are unknown. Crossβtolerance with other serotonergic psychedelics is expected.
