Musculoskeletal repair research focuses on angiogenesis, fibroblast activity, inflammation resolution, and extracellular-matrix remodelling. Experimental peptides such as BPC-157 and thymosin-β4 fragments are studied mainly in animal and cell models — human clinical evidence remains limited.
Narrative enthusiasm online often outruns the peer-reviewed record. Prefer primary papers and recent systematic/narrative reviews that state evidence gaps clearly.
