Any drugs that can emulate exercise?

[Richard Masters]

Are there any drugs that have the same effect on the brain as exercise? Specifically any drugs that might have the same effect on mood, and memory?

ETA: Yes - I'm asking if I can get the psychotropic and neurological benefits of exercise without doing any exercise.

Exercise is supposed to release endorphins, which alter mood. Opiates like heroin have a similar mood-enhancing effect.

That's what I need. ;)

I did a search and found that it's suspected that it's not just endorphins, but also a mix of adrenaline, dopamine, and serotonin.
