You are probably right on the specifics, but serotonin is produced/located in the gut, and its an incredibly important neurotransmitter.

One day people will figure out how to use these correctly.

Serotonin in the gut doesn’t go to your brain. It serves a different function in the gut.

The brain synthesizes serotonin inside of the brain. It doesn’t come from your gut.
