@robinson when referred to as IPF doesn’t that mean you don’t know what caused the fibrosis? We do know what caused my husband’s. It was working in carcinogenic environment most of his life. He’s 76 yrs old. I would guess the symptoms & treatment would be the same either way. Are you experiencing no side effects from the olev? I’m not familiar with stem cell therapy. I’ll research it. Thanks for your info!! I wish you the best!!
