GHK-Cu vs BPC-157: Which Is Right for You?
GHK-Cu is a naturally occurring copper tripeptide used mainly in topical cosmetics; BPC-157 is a synthetic 15-amino-acid peptide studied almost entirely in animals. Neither is FDA-approved as a drug, and both are sold as "research" injectables.
Side-by-side comparison
| GHK-Cu | BPC-157 | |
|---|---|---|
| Size | Tripeptide (Gly-His-Lys) + copper | 15 amino acids |
| Origin | Found in human plasma | Derived from a gastric protein sequence |
| Main human use | Topical cosmetics | None approved |
| Evidence base | Cell, animal and small cosmetic studies | Mostly rodent studies |
| Sports anti-doping | Not specifically listed | Prohibited (WADA S0) |

Key takeaways
- Neither has an approved injectable drug product.
- GHK-Cu's human data are mostly topical skin studies.
- BPC-157 is on WADA's prohibited list.
What are GHK-Cu and BPC-157?
GHK-Cu is the copper complex of the tripeptide glycyl-L-histidyl-L-lysine, which occurs naturally in human plasma; it is used in topical cosmetics and has been studied for skin and tissue repair, but it is not an FDA-approved drug.
BPC-157 is a synthetic 15-amino-acid peptide derived from a sequence in a human gastric protein; it has been studied mainly in rodents for tissue repair and is not FDA-approved for any use.
Mechanism differences
GHK-Cu binds copper and has been reported in lab studies to influence collagen synthesis and wound-repair genes. BPC-157 has been reported in animal studies to affect blood-vessel growth and nitric-oxide signaling.
Effectiveness
Topical GHK-Cu cosmetic studies report modest improvements in skin measures. BPC-157 has many rodent studies of tendon, gut and muscle injury but very few published human data.
Side effect profiles
Topical GHK-Cu is generally well tolerated in cosmetic use. Injectable safety data for either are lacking; unregulated injectables carry contamination risks.
Dosing & administration
Neither has an approved dose. See vial-math pages for arithmetic only.
Cost

FDA & regulatory status
Neither is an FDA-approved drug. GHK-Cu is widely used as a cosmetic ingredient.
Who should choose which
There is no clinical basis to choose either for injection.
What the evidence does not show
- Controlled human trials of injectable GHK-Cu or BPC-157 for injury healing.
Frequently asked questions
Is GHK-Cu the same as copper peptides in skincare?
Yes. GHK-Cu is the best-known copper peptide in cosmetics.
Is BPC-157 banned in sport?
Yes. WADA lists BPC-157 under S0 (non-approved substances).
Are they FDA-approved?
No. Neither is approved as a drug.
