I've seen news related to this FX-322 drug, but it's never clear to me if this works or not, or if it will be available to the public somehow. I lost my hi-freq in one ear due to inflammation if the cochlea (vestibular neuritis). Would love to know if this could help grow those hair cells back. That also gave me tinitus, but I don't really care about tinitus, I just want to get those frequencies back. Also found there's FX-345: https://www.youtube.com/watch?v=bV4js_9GUwc https://www.youtube.com/watch?v=bV4js_9GUwc
