Long post, sorry. KPV: what actually has human evidence behind it, and what is extrapolation from animals?

The comparison group matters more than the compound when the outcome is something as fuzzy as focus.

I have started logging dose, time, and sleep because otherwise the anecdote is just a mood.

Forum consensus and published consensus diverged here about five years ago and never reconverged.

Cold storage, light protection, and a date on the vial. Boring, and it removes half the variables.

Where does the human data stop and the extrapolation start?
