GHK-Cu vs. BPC-157
| Attribute | GHK-Cu | BPC-157 |
|---|---|---|
| Mechanism | Copper-peptide signaling + collagen synthesis | VEGF/FGF angiogenesis + NO pathway |
| Admin Route | Topical (primary), injectable | Injectable (primary), oral (gut) |
| Best For | Skin aging, wound healing, hair, topical collagen | Tendon, ligament, gut, systemic injury healing |
| Evidence Quality | Limited human data (mostly in-vitro) | Animal models (robust preclinical) |
| Availability | OTC creams + injectable research grade | Injectable or oral research grade |
Verdict: GHK-Cu excels in topical applications for skin, hair, and superficial wound healing. BPC-157 is the preferred option for deep tissue, joint, and GI injury repair. Many longevity protocols combine both.
