This comparison does not assign a generated winner or score.
- Thymosin Alpha-1 (Tα1)
- TLR9 agonist, dendritic cell activation, Th1 cytokine upregulation
- ~2 hours (plasma)
- 1.6mg subcutaneous 2x weekly
- Men >40 with thymic involution, chronic infections, immune senescence
- Gold standard for thymic hormone replacement. Two decades of clinical safety data, mechanism directly addresses age-related T-cell deficits
- Thymalin
- Polypeptide thymic extract (mixture), broader hormonal signaling
- Variable (complex mixture)
- 10–30mg intramuscular weekly
- Same as Tα1, some researchers prefer whole-gland extracts
- Less precise than Tα1 due to undefined peptide composition. Efficacy depends on batch standardization
- Epithalon (Epitalon)
- Telomerase activation, pineal gland modulation
- ~3 hours
- 5–10mg subcutaneous daily (10–20 day cycles)
- Longevity research, circadian rhythm support
- Different target. Focuses on cellular aging rather than immune-specific pathways, not a thymic peptide
- TB-500 (Thymosin Beta-4)
- Actin sequestration, tissue repair, angiogenesis
- ~1.5 hours
- 2–5mg subcutaneous 2x weekly
- Injury recovery, wound healing
- Unrelated to thymosin alpha-1 despite naming. No direct immune modulation, primarily regenerative
