BPC-157 & TB-500 Research for Bulging/Herniated Discs

First time posting here. I know BPC-157 and TB-500 get talked about a lot, so I was curious what research is out there on them for bulging or herniated discs.
Has anyone come across any good studies or research involving a research subject with lower back disc issues? Particularly with pain in extension and extreme tightness in flexion. I’m mainly interested in what the research shows about healing, inflammation, or recovery related to disc injuries.
Thanks.
