It sounds pretty unique how chloro PEA psychs can have a tranquilizing or serene meditative quality apparently, at least so far I noticed 25C and 2C-C have it and DOC is also reported to show it, or at least it can.
Maybe your potentiation is rather because the DOC overruled effects but still got potentiated simply because of competitive enzyme inhibition? Basically if you eat something that is also a substrate for the enzyme that is supposed to break down the drug you are tripping on, more enzymes could get preoccupied and the effects will get stronger even if the added compound is not active itself, correct? I suspect some of the secondary alkaloids in mushrooms act that way, which is half way and vaguely in the direction of MAOI but of course not necessarily quite the same.
I wonder if it is worth experimenting with adding the basically inactive 2C-H to another 2C-X compound that is actually active, to see if there is potentiation of the active 2C-X.
