Research Summary

Preclinical

In a landmark 15-year study by Khavinson and colleagues, elderly patients receiving annual courses of thymalin and epithalon showed a 28% reduction in mortality compared to controls, along with significant improvements in immune markers, endocrine function, and cardiovascular health. Thymalin has been used clinically in Russia for over 30 years in immunocompromised and geriatric patients. Western clinical trial data remains limited, but the existing body of research is substantial.
