What I want is a pill that makes me exercise.
I unironically offer the opinion that half a teaspoon of creatine is a much better alternative.
ADHD patients seem to be able to exercise just fine (and -importantly- don't seem to be suffering widespread muscle death) when on Adderall and similar. I bet folks like that are pretty glad that the body is a complex, robust system that does reasonably well in a fairly wide range of internal and external environments.
So, respectifully to the studies, im calling bullshit.
Look up the Regeneron COURAGE trial
