So as far as I know, there aren't any really good at home blood tests for things like serotonin and dopamine. There's some commercial products out there. But to me, just to me, I'm not particularly impressed. You know, it's not the same as getting your hormones levels measured or your metabolic factors measured, that's can be daunting. It can be done rigorously. There are tests out there.
