- BPC-157
- TNF-alpha downregulation, NF-kB inhibition, angiogenesis
- 250–500 mcg subcutaneous daily
- Multiple animal models, limited human RCTs
- Strongest preclinical evidence for nerve compression inflammation
- Thymosin Beta-4
- VEGF upregulation, endothelial migration, tissue repair
- 2–5 mg subcutaneous twice weekly
- Human tissue repair studies (tendon, muscle)
- Indirect evidence via vascular repair mechanisms
- Cerebrolysin
- NGF/BDNF mimetic, axonal regeneration support
- 10–30 ml intramuscular 3x/week
- Human neuropathy trials show nerve conduction improvement
- Direct evidence in peripheral nerve pathology
- KPV
- NF-kB inhibition, IL-6/IL-8 suppression
- 500 mcg–2 mg subcutaneous daily
- Human IBD and dermatology trials
- Established anti-inflammatory profile, untested in sciatica
- Dihexa
- HGF receptor activation, synaptogenesis
- 1–5 mg oral daily (research contexts)
- Animal models only, no human peripheral nerve data
- Theoretical benefit via neural repair pathways
- The critical distinction: peptides help sciatica when they address the inflammatory biology at the nerve root. Not when they're marketed as generic 'pain relief.' BPC-157 and TB-500 have the strongest mechanistic rationale because they target the specific pathology (cytokine-driven inflammation and ischemic tissue damage) that keeps sciatica chronic. Cerebrolysin shows direct human evidence in peripheral neuropathy contexts. KPV and Dihexa have plausible mechanisms but lack sciatica-specific trials.
