It may have some slightly unpleasant fx going off the Pihkal entries of DOBU but they were pretty inconclusive probly because the experimenters didn't feel it would get much better at higher more active dosages? I honestly don't think it would be worth synthing, I don't think it would have any real cool or mindblowing potential as a psychedelic, the heavier the alkyls get after propyl/isopropyl drop dramatically. I think it will be active but not in a good way, look at buscaline in pihkal, it seems like it matches up to the other few 4-butylated compounds, more nasty bodyload than fun/psychedelic drug
