appetite suppression.
may also provide mild aromatase inhibition (common effect of dopaminergics).
some reduction in prolactin.
pramipexole is a better option for all those and increases GH.
cabergoline is also more effective at all of the above, though without GH increase.
selegiline is fairly comparable in effect to bupropion, their metabolite action is very similar, but IMHO selegiline is better tolerated and more effective from a number of standpoints as compared to bupropion.
