I would say with the oral 40mg phosphate its impossible to tell .. but to anyone who has taken more and esp. the freebase esp. nasally: would you agree?
I already said that in many very minor ways, NSI-189 reminds me of magic mushrooms. 4-AcO-DMT is just a "purer" version of that. Not to be confused with hallucinogens like LSD or Amanita Muscaria. No .. pretty much specifically low dosed psilocybin shares similarities to regular or twice to triple as much dosed NSI-189. Sort of the colors, the emotional uplift, the thinking patterns. But then again, its not the same oc couse.
Mysterious af best. What do you think?
http://swisstargetprediction.ch shows no such similarity in receptor binding btw.
