- GHK-Cu
- Activates lysyl oxidase for collagen crosslinking; downregulates MMP-1
- Twice daily (short half-life: 1.5–2 hours)
- Tensile strength at 14 days post-injury
- 14 days at 2–8°C (light-sensitive)
- Best for matrix remodelling and structural integrity outcomes
- TB-500
- Sequesters G-actin to regulate cell migration; reduces inflammatory cytokines
- Once daily or alternate days (half-life: 12–16 hours)
- Re-epithelialisation rate (days to closure)
- 28 days at 2–8°C (oxidation-prone)
- Best for accelerating wound closure and reducing inflammatory phase duration
- Combined Protocol
- Synergistic collagen synthesis + accelerated migration
- GHK-Cu twice daily + TB-500 once daily
- Closure rate AND tensile strength combined
- Separate storage required for each peptide
- Optimal for studies requiring both speed and structural quality of repair
