Comparison
GHK-Cu vs BPC-157
Skin-and-repair peptides with different evidence
The key difference
GHK-Cu is a naturally occurring copper-binding peptide used widely in topical skincare. BPC-157 is a synthetic peptide studied mainly in animals for tissue repair.
| GHK-Cu | BPC-157 | |
|---|---|---|
| Class | Copper-binding tripeptide | Synthetic gastric peptide |
| Evidence | Early human research | Mostly animal research |
| Status | Used in cosmetics. Not FDA-approved as a drug. | Not FDA-approved for any use. |
| Also known as | Copper peptide | Body Protection Compound-157 |
| Researched for | Skin & hair, Recovery & repair, Longevity | Recovery & repair |
| Evidence strength | Early human research | Mostly animal research |
What else differs
- GHK-Cu has small human studies, mostly of topical formulas, and is a common cosmetic ingredient.
- BPC-157 has very limited human data and is not approved for any use.
Bottom line
GHK-Cu has a longer track record, mostly in skincare; BPC-157 remains largely preclinical.
