- Cerebrolysin
- Neurotrophic factor delivery, glutamate regulation, synaptic plasticity
- Limited (relies on receptor-mediated uptake at BBB)
- Strong. Six RCTs in moderate TBI, meta-analysis shows benefit
- 30–50 mL IV daily × 10–21 days
- Best-evidenced compound for acute TBI; logistically complex (IV administration)
- Dihexa
- HGF/c-Met pathway activation, synaptogenesis, cognitive enhancement
- Excellent (lipophilic, 60% oral bioavailability)
- Weak. One small pilot study, case reports only
- 1–5 mg/kg oral or SC daily × 14–28 days
- Strongest preclinical cognitive data; human dosing protocols still exploratory
- P21
- CREB activation, BDNF gene expression amplification
- Moderate (small MW ~1,500 Da, passive diffusion)
- None. Preclinical only
- 5–10 mg IM/SC every 48–72 hours × 2–3 weeks
- Mechanistically compelling (epigenetic BDNF boost); lacks human trial data
- BPC-157
- Anti-inflammatory, angiogenesis, gut-brain axis modulation
- Uncertain (conflicting data on CNS penetration)
- None. No TBI-specific trials
- 250–500 mcg SC daily × 4–6 weeks
- Popular in biohacking circles; mechanism for brain injury unclear
