I was a guinea pig in a clinical trial for a drug that was meant to help with social symptoms of autism, the mechanism of which had something to with vasopressin (I don't know the details): https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9260643/ https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9260643/ . It didn't do anything for me and the study got cancelled after I'd been taking the drug for some months.
