Editor's note
BPC-157 has corneal healing data; GHK-Cu offers broader tissue support.
| Criterion | BPC-157 | GHK-Cu |
|---|---|---|
| Corneal healing focus | Strong (preclinical) | Growing (copper signaling) |
| Retinal protection | Limited | Emerging (antioxidant copper) |
| Ocular tissue breadth | Moderate (corneal) | Growing (multi-tissue) |
| Preclinical eye models | Substantial | Moderate |
