Anyone have experience or wisdom on jak inhibitors/peptides or ANYTHING for universalis??

Hey guys, so recently been chasing the rabbit down the rabbit holes of learning about jak inhibitors and copper peptides with regard to hair regrowth. Wondering if anyone has had ANY experience with either of these, or anything for alopecia universalis. I am a SEASONED alopecia veteran and haven't really gone at any length to get my hair back just been living with it for a long time, and accepted this was life long ago but recently seeing some of these medicines and it's efficacy has me thinking. Would love to have a discussion with anyone else who has some insight. Thanks!
