Molecular Data
Epitalon Thymulin
Weight 390.35 Da 857 Da (peptide), 921 Da (with zinc)
Half-life Not established (short peptide) ~10 minutes (free form); extended with nanoparticle formulations
Chain 4 amino acids 9 amino acids
Type Tetrapeptide Thymic nonapeptide hormone
Key Benefits
Epitalon
01 Telomere extension and cellular replicative lifespan extension
02 Enhanced melatonin production
03 Improved immune function
04 Potential lifespan extension (25-33% in animal studies)
05 Systemic anti-aging through cellular rejuvenation
06 Short cycle duration with long-lasting effects
Thymulin
01 Essential for T-cell maturation and differentiation
02 Modulates immune responses (immunomodulatory)
03 Anti-inflammatory properties
04 Declines with age - restoration may combat immunosenescence
05 Well-defined single peptide (unlike extracts)
06 Studied in autoimmune disease research
07 Neuroendocrine regulatory effects
08 Zinc-dependent activity allows for regulation
