I Would be very careful. MAOIs can cause serious interactions. Unless it was yage, I would never mix an MAOI with anything, but then again, I like to err well on the side of caution
MAOIs and Tryptamines are a fairly "safe" combination because the effect is pretty much predictable (the trypatime in question will just act more "potently" due to the expanded half-life). The MAOI + (
N,N/5-MeO)-DMT is of course the classic combination, but Psilocybin/Psilocin work also nicely.
But when starting to mix MAOIs with other kind of subtances than tryptamines, one should be extremly careful. And as always when using MAOIs one should be aware of the substances to avoid for example with food and medication (tyramine- and serotonine-shocks are not things to fool around with).
