Neurotransmitter metabolites. Okay, 90% of people we've tested have low levels of dopamine, endorphins, so the whole catakolamine family and serotonin. And this is measured with metabolites in the urine. And so it's called homovanelic acid or HVA for short. You can measure this. And when you talk with someone who is depressed, they're bored easily, they've been diagnosed with ADD or ADHD, they have issues with focus and concentration, we can see the low dopamine on paper.
