I took 30mg of 4-HO-MiPT (tripped 2 days before though) an hour before 150mg really good MDMA. It was amazing, added some visuals to the roll but overall I felt like the tryptamine was completely overpowered. Might have been tolerance, but there were only positives ime.
Coming up on both at the same time might be rough, I'd take the psychedelic first any day.
