For me, 150mg Moclobemide + 125mg DMT fumarate + 3mg melatonin produced an experience of a distinctly different character than Moclobemide and DMT alone. Much more out of body, and incredibly blissful and dreamy...it was a very powerful combo and I definitely wouldn't have wanted any more DMT than I had then. Had strong feelings of energy/buzzing around my third eye/pineal. Definitely an interesting experience...have not noticed melatonin potentiation with other combinations however.
