The thing is though, harmala alkaloids have their own psychoactive effects and some might not want to convolute the psilocybin experience with another substance. In these cases I'd say that to get desired effects, taking a higher dose is fine and entirely logical.. just as you would with any other substance. Harmalas aren't really something I'd consider adding to mushrooms anymore since psilocybin is essentially orally active DMT already. Of course, I am advocating sensible increase of dose here, in order to reach desired effects.. not taking ten times what is already considered a high dose.. that is bonkers.
