I understand the difference in mechanism of action. what I don't understand is both should be stimulants and activate dopamine neurons.
I managed to get sample of both and confirmed diametrically different effects. low dose amphetamine made me motivated to do things i'm normally too lazy to do, and do it efficiently, while in good mood. sex was great.
one week later, sustained release low dose of methylphenidate made my apathy worse, gave me low grade headache, some feeling of warmth in head, but I had to lay down, and accomplished nothing. mood was dysphoric (a bit irritable) and sex was just OK.
why would that be so different, again?
