- The table below compares the peptides most frequently discussed in tinnitus research, focusing on mechanism, evidence quality, and practical considerations for research use.
- BPC-157
- Reduces cochlear inflammation via cytokine modulation; supports nerve healing through VEGF upregulation
- Animal models show 35% faster ABR recovery post-ototoxicity; no human RCTs
- 250–500 mcg subcutaneous daily
- Most effective when started within 72 hours of acoustic trauma
- Strongest mechanistic rationale for acute noise-induced tinnitus
- Cerebrolysin
- Neurotrophic support for spiral ganglion neurons; prevents auditory nerve apoptosis
- Animal studies + small human case series; intratympanic administration tested
- 5–10 mL intramuscular 3x/week or 0.3 mL intratympanic injection
- Requires clinical administration for intratympanic route
- Best supported for nerve degeneration-driven tinnitus
- Thymalin
- Modulates T-cell function; reduces autoimmune inner ear inflammation
- Case series (n=4) showed TFI score reductions; no controlled trials
- 10 mg subcutaneous daily for 8–12 weeks
- Relevant only for autoimmune-driven cases (AIED)
- Niche application. Requires confirmed autoimmune pathology
- MK-677
- Increases IGF-1 to support cochlear synapse maintenance
- IGF-1 supplementation restored synapse density in aged mice; indirect tinnitus evidence
- 12.5–25 mg oral daily
- Systemic metabolic effects; not tinnitus-specific
- Supportive role in age-related or metabolic tinnitus
- Dihexa
- Promotes synaptogenesis in auditory cortex; may reduce central hyperactivity
- No direct auditory studies; mechanism extrapolated from cognitive research
- 2–5 mg oral daily
- Entirely theoretical for tinnitus; no clinical data
- Experimental only. Mechanism plausible but untested
