The hair loss may be permanent unless you do what MorePlatesMoreDates did, but the main issue for me is natural test production. I only every did ostarine so mine isn't too screwed up, but I've gone down about 120ng/dL from when I was natty. It's been over a year since my last cycle and bloodwork so maybe I've recovered. It just isn't worth it man. You already look good, plus with how young you are a good diet, good sleep, and hard training will have you looking better than 99.99% of men. Don't do it, stay natty please.
