- Thymalin
- Immune modulation via thymulin upregulation
- Reduced inflammatory cytokines and improved CD4+/CD8+ ratios in men >60 with BPH (Advances in Gerontology, 2019)
- 10mg IM every other day × 10 doses
- Strongest evidence for immune-driven prostate inflammation. Limited by availability outside Eastern Europe
- Epithalon
- Telomerase activation, oxidative stress reduction
- 33% increase in telomerase activity in reproductive tissues, 27% reduction in lipid peroxidation markers (Bulletin Exp Bio Med)
- 10mcg SC daily × 10 days, cycles repeated quarterly
- Addresses cellular aging mechanisms. Long-term human data still limited to Russian studies
- BPC-157
- VEGF upregulation, FAK-paxillin modulation, tissue repair
- Reduced inflammation-induced fibrosis in urethral/bladder tissue in rodent models (J Physiology-Paris)
- 250–500mcg SC daily × 4–6 weeks
- Broad tissue repair activity with low side-effect profile. Extrapolation from animal models requires caution
- KPV
- NF-κB inhibition, anti-inflammatory cytokine suppression
- 70% reduction in TNF-α/IL-6 in activated macrophages (Inflammation Research)
- 500mcg–1mg SC daily
- Potent anti-inflammatory. Minimal human prostate-specific data, mechanism supports use
- MK-677
- Pulsatile GH release via ghrelin receptor agonism
- No significant PSA or prostate volume increase in 2-year trial (JCEM). Indirect metabolic benefits
- 25mg oral daily
- Safe metabolic support. Not a direct prostate intervention, useful for addressing insulin resistance
