The buspirone challenge test clearly distinguishes ME/CFS patients from healthy controls: why is it not being developed and deployed?

In addition to the four or five papers on the buspirone challenge tests in the 1990s I remember there was also some work on assessing prolactin responses to d-fenfluramine challenge, e.g. in -

Contrasting neuroendocrine responses in depression and chronic fatigue syndrome

I don’t want to derail, but LDN raised my prolactin quite high into the high 40s. I washed out for 6 months, took a test before challenge again, was around 20. Started LDN and my prolactin went once again into the high 40s when I tested a month later. I’ve tested since and multiple times now hover around 20.

I noticed due to sexual side effects, nipple sensitivity , and hair loss. There is lots and lots of anecdotal post on the FB page LDN for me/cfs of hair loss but no one checks prolactin. They just stop the meds.
