- BPC-157
- VEGF upregulation → angiogenesis
- Phase II diabetic ulcer trial: 42% faster healing vs standard care (University of Split, 2025)
- Topical or subcutaneous injection near injury site
- 5–7 days at 2–8°C once reconstituted
- Most extensively studied for dermal wounds; mechanism is well-characterised; requires sterile reconstitution
- GHK-Cu
- Copper delivery to fibroblasts → collagen synthesis
- 70% increase in procollagen production in vitro; 68% ulcer closure at 8 weeks in venous leg ulcer trial (Journal of Wound Care, 2025)
- Topical application to wound bed
- 10–14 days at 2–8°C once reconstituted
- Best-in-class for collagen deposition; copper component is critical (not replaceable with zinc or other metals)
- TB-500
- Keratinocyte migration acceleration + anti-inflammatory cytokine suppression
- 40% faster epithelial migration in scratch assays; 30–50% reduction in IL-6 and TNF-α (Wound Repair and Regeneration, 2024)
- Subcutaneous injection proximal to injury
- 7–10 days at 2–8°C once reconstituted
- Superior for reducing inflammation in acute injury; less data for chronic wounds compared to BPC-157
- Epitalon
- Telomerase activation (mechanism unclear for wounds)
- No published human wound healing trials as of 2026; rodent data only
- Not recommended for wound protocols
- Insufficient evidence for wound healing claims; primarily studied for ageing/longevity rather than tissue repair
- Before selecting a peptide, verify the research context matches your application. A peptide effective for tendon repair in rats may not translate to human dermal wounds. The peptides in the top three rows have human clinical data; the bottom row does not.
