Meth goes for the dopamine, norepinephrine, and serotonin receptors, and it hits them hard. This combo gives you energy, focus, speediness, and euphoria. PEA only goes significantly for the dopamine and norepinephrine receptors, thus giving you some speediness but much less, if any, euphoria. Now, PEA's effects can be increased by taking it along with a MAO inhibitor, but taking meth with a MOA inhibitors is risky business. I don't really see much benefit in taking PEA and meth together, its kind of like taking coffee with amphetamine, it only adds to the jitteriness but not the high.
