  • BPC-157
  • Downregulates NF-κB signaling, promotes VEGF and FGF expression for nerve tissue repair
  • Animal studies with consistent replication; no Phase III human trials
  • Mechanical nerve injury (compression, transection), post-surgical neuropathy
  • Subcutaneous injection or oral (gastric stability demonstrated)
  • Strongest evidence base for peripheral nerve regeneration; mechanism well-characterized; lacks large human RCT data
  • Thymosin Beta-4
  • Regulates actin polymerization in growth cones; promotes axonal extension and reinnervation
  • Multiple animal models; small human studies in cardiac and corneal repair
  • Diabetic neuropathy, small fiber neuropathy, chemotherapy-induced peripheral neuropathy
  • Subcutaneous injection
  • Robust preclinical data; promotes structural repair rather than symptom masking; human neuropathy trials needed
  • Cerebrolysin
  • Neurotrophic peptide mixture; upregulates BDNF, NGF, and CNTF; anti-apoptotic effects
  • Meta-analyses in stroke and dementia; emerging peripheral neuropathy data
  • Central and peripheral neuropathies; diabetic nerve damage with CNS component
  • Intravenous infusion (approved route in 40+ countries)
  • Best-studied in CNS contexts; peripheral nerve evidence growing; IV administration limits accessibility
  • The comparison reveals a pattern: peptides help nerve pain through documented biological pathways, but clinical translation lags mechanistic understanding. BPC-157 has the most robust peripheral nerve data in animals. TB-4 shows promise across multiple neuropathy subtypes. Cerebrolysin has the most human data but mostly in CNS injury rather than peripheral neuropathy.
