- TB-500
- G-actin sequestration + laminin-5 upregulation
- 2.5–3× baseline at 48h
- 10–100 µM in vitro, 6–10 mg/kg in vivo
- Broad (epithelial, endothelial, fibroblast)
- Gold standard for migration enhancement—works across cell types with minimal off-target effects. Required for protocols prioritizing directional migration over proliferation.
- BPC-157
- VEGF receptor upregulation + FAK activation
- 1.8–2.2× baseline at 72h
- 1–10 µg/mL in vitro, 200–400 µg/kg in vivo
- Vascular endothelium, gut epithelium
- Strong angiogenesis component makes it superior for ischemic wounds. Migration effect is secondary to vascular remodeling—less effective in non-vascular tissues.
- GHK-Cu
- Integrin activation + MMP regulation
- 1.5–1.9× baseline at 96h
- 1–10 µM in vitro, topical application in vivo
- Dermal fibroblasts, keratinocytes
- Excellent for extracellular matrix remodeling but slower kinetics. Best combined with TB-500 in two-phase protocols (TB-500 for acute migration, GHK-Cu for matrix stabilization).
- Epithalon
- Telomerase activation + limited actin effects
- 1.2–1.4× baseline at 120h
- 0.1–1 µg/mL in vitro, 10 µg/kg in vivo
- Stem cells, senescent fibroblasts
- Weak direct migration effect. Useful in aged tissue models where cellular senescence limits response to other peptides. Not a first-line migration enhancer.
- The comparison shows TB-500 delivers the fastest, most consistent migration enhancement across tissue types. BPC-157 offers stronger angiogenic support but requires higher concentrations for equivalent migration speed. For researchers focused specifically on cell motility rather than vascular remodeling, TB-500 remains the most mechanistically direct option.
