Amitriptyline is not a tryptamine, the names only sound alike nothing more.
Pushing it with 5-MeO-DALT with a compound that may inhibit serotonin reuptake, is a MAO substrate of kinds and also a stimulant? What to suggest to expect? Probably dangerously high blood pressure, overheating and the sweating that goes along with it, confusion, flipping from feeling good to losing grip on feelings of hot and cold to not feeling good, all of which will be taxing for most organs in your body, all of which depend on how far you push it.
Psychologically before you lose it or in case you don't, there can be anything between psychedelia (tripping), stimulation, feeling more empathy.
Most probably things that can achieved as well with drugs that do play nice. In theory as well as in reality.
You may go ahead anyway (why even come here to ask if it's safe?), and you may feel like you get away with it. But that would still not guarantee that it's not dangerous or bad for you.
Focussing on the chance that you may survive it let alone appreciate it, is dumb and foolish. Just accept what fun there is to be had with things that are not likely to mess you up severely.
And if you please, random sharing of drug-related experiences like that are best posted in any forum's social thread - just so you realize
