Can anyone cite a source that proves that botox injection to relieve headaches isnt an experimetnal treatment?

Question

PLEASE cite your source, I need reliable, citable sources, I am preparing a case and need help finding the research, if you can just give me a website or book to check that is considered reliable in the medical community I will take that too. Please feel free to tell me if you've had this treatment and if it worked for you too but mostly I need proof that it is NOT an experimental but reasonable course of treatment for severe headaches, the more things I can cite in medical journals etc the better. THANK YOU!
