Tears and tendinopathy of the shoulder's rotator cuff — one of the most common reasons people look into repair peptides.
Rotator cuff injuries — from tendinopathy to partial and full-thickness tears — are slow to heal because the tendon's blood supply is poor. That's exactly why the angiogenic and tissue-repair peptides attract interest here: the theory is to support the blood-vessel formation and cell migration the tendon struggles to manage on its own.
BPC-157 and TB-500 are the most-discussed compounds in this context, usually as a defined healing block. The honest framing: human evidence is preclinical and anecdotal, these are research compounds, and a real cuff tear needs imaging and a physio or orthopaedic opinion — not peptides alone.
Ranked by editorial relevance — a measure of how central each compound is to the conversation, not a claim of effectiveness.
| Compound | Type | Why it's relevant |
|---|---|---|
| BPC-157 | peptide | Angiogenic, cytoprotective; the most-discussed tendon-repair peptide. |
| TB-500 (Thymosin Beta-4) | peptide | Actin regulation; supports cell migration to the injury. |
| GHK-Cu | peptide | Collagen-synthesis support for connective tissue. |
