- Thymalin
- Thymic immune regulation; modulates T-cell activity and suppresses inflammatory cytokines (IL-6, TNF-α)
- Observational study (St. Petersburg Institute). 30% cytokine reduction, 40–50% hot flash frequency reduction over 8 weeks in postmenopausal women
- 5–10 mg subcutaneously 2–3×/week
- Subcutaneous injection
- Most directly studied for vasomotor symptoms; immune modulation approach avoids estrogen receptor risks but lacks placebo-controlled RCTs
- KPV
- Inhibits NF-κB translocation; blocks inflammatory gene transcription; crosses blood-brain barrier
- Preclinical models show 50–70% reduction in IL-6/TNF-α; no direct human trials for menopause-related symptoms
- 500 mcg – 2 mg subcutaneously daily or every other day
- Strong anti-inflammatory profile with CNS penetration; theoretically sound for hypothalamic inflammation but human menopause data is absent
- BPC-157
- Tissue repair and angiogenesis; broad anti-inflammatory effects via modulation of growth factor pathways
- No direct vasomotor symptom studies; reduces systemic inflammation and supports mucosal/vascular healing in animal models
- 250–500 mcg subcutaneously daily
- Indirect benefit possible through general inflammation reduction; not specific to thermoregulatory pathways. Use as adjunct only
- Selank
- Anxiolytic and immune-modulating; synthetic tuftsin analog; regulates monoamine and cytokine balance
- Reduces anxiety and HPA-axis hyperactivity in clinical trials; no menopause-specific research
- 300–600 mcg intranasally or subcutaneously daily
- Intranasal or subcutaneous
- May help if hot flashes are exacerbated by anxiety and stress; not a primary vasomotor intervention
