Potentially mood elevating / anti-depressant but unsafe (serotonin syndrome etc). Can apparently be very mildly psychedelic according to BL user ho-chi-minh, but does not sound interesting. Even if this can throw your neurotransmitter synthesis and conversions out of whack, it's quite hard to make significant doses of the right neurotransmitters without it getting extremely unsafe; without also making unwanted neurotransmitters, or without getting them in the wrong places causing nasty side effects and nausea; without losing control over the concentrations - so IMO it is better not attempted whatsoever.
You must mean MAOI - which are of course effective at protecting drugs like DMT from being metabolized rapidly, but again: it is tricky and unwise to tinker with your own neurotransmitters - doing so would either be rather pointless or too dangerous, so I don't see how it would be worth trying.
