The ebook I linked to has an appendix that lists doctors offering IV therapy. The book was written 2008 though.after I got a very bad flu and it got better, the next day I felt much worse and suspected pneumonia so I went to the doctor (very very rare for me) for a chest x-ray. The doctor was a contract employee of urgent care, but he was fairly unusual and he thought I had COVID-19 and recommended I get hydrogen peroxide intravenous therapy (but not from him -- he didn't know who offers this, but thought it was a good idea.) Good for a few doctors like this who aren't completely close minded.
Read also the first chapter. It's an engaging read. I wanted to share some excerpts as they are worth sharing.
It's not practical for me to seek IV therapy because of the current situation. I hope the oral route would work.
