Long post, sorry. Zadaxin (thymosin alpha-1): what actually has human evidence behind it, and what is extrapolation from animals?

If you need three other compounds to notice the first one, you have not tested the first one.

I would rather have a narrow conclusion and be right than a broad one and be interesting.

The effect size I actually noticed is roughly a third of what the write-ups imply, and it took two years to be sure.

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

Animal data is much of what exists here and the human stuff is thin and small.

Willing to accept that my own experience is the weakest evidence in the room.
