Signal.
A biologic that signals the brain to repair itself — backed by a clinical network and a closed-loop AI that reads your baseline back to you.
One network. Every clinic in the loop.
Signal is delivered through a network of physician-led clinics, connected by a closed-loop AI. Every baseline, every reading, and every protocol update flows through the same loop — so each clinic practices with the knowledge of the whole network.
Your brain knows how to repair itself. It just lost the signal.
One bottle. Multiple metered doses.
Nose to brain.
The BBB doesn't apply here.
Signal exosomes cross the cribriform plate directly. No injection. No infusion. Ninety seconds, in clinic.

A 90-second baseline of six cognitive markers — and the clinical network's closed-loop AI reads your results back in plain language.
Take the Mind Diagnostic →Answers, on the record.
A clinical network — physician oversight with a closed-loop AI trained on Signal's science, protocol, and physician program. Ask about the mechanism, the dose, or what your Mind Diagnostic reading means.
