I Do remember what You say Amsterdam X about taking 25mg of DOI!. I was told exactly as You say.Apparently there was somebody selling a few Research Chemicals:2CC,2CI,DOC and DOI.The guy received a shipment of 2CI,but eventually it was DOI!.He did not tell people about that!. How possibly Do You now what you're about to take is DOI!,instead the 2CI you bought......I've taken until 10mg of DOI and becomes very visual but 25mg...... Is not your fault like many people happened the same. DOI at dosage of 5....7 mg is very interesting,
