Dopamine definitely causes a confidence feeling.
Many people raise dopamine and noradrenaline, (ne), for their work, even if it's low doses to be more productive, not be as hungry, and have more energy
Mdma has all of this going on combined with big or massive serotonin, depending on the dose, more is not better ime, and common sense what goes up must come down so you don't have to have a massive crash from serotonin, oxytocin, and others going way above baseline and crashing way below baseline
I recommend doing it with someone you love and in a sexual relationship with,if possible and taking the whole next day off to spend with them, as from my fifty plus nights mostly and a few days of rolling it makes the comedown less but it needs to be with someone you truly live and consider a soul mate bc a friends with benefits , when she blocked me, and knew she was seeing other dudes, caused the emotions to be amplified two days into the comedown so you must protect yourself with who you don't with
Some say just do it with a friend with benefits and realize it's just that but for me that didn't work as it amplified negative emotions and only best to do it with someone your super in love with, otherwise out with friends to nightlife or even solo can be fun but I'm at the age where in five years or so i probably wouldn't do house parties, raves, edm clubs and even dance clubs anymores, in mid forties
