Thymalin

A peptide bioregulator derived from the thymus gland, developed by Russian researchers Khavinson and Morozov. Thymalin restores immune function by supporting T-cell maturation and thymic activity, which naturally decline with age (thymic involution). It has been studied extensively in geriatric populations for its immune-restorative and longevity-promoting effects.

• Promotes differentiation and maturation of T-lymphocytes
• Restores thymic microenvironment function in aged tissues
• Modulates cytokine production toward balanced immune responses
• Supports neuroendocrine-immune axis regulation

• Organ transplant recipients on immunosuppression
• Active autoimmune disease flares
• Pregnancy or breastfeeding

Store at 2–8°C (36–46°F) for up to 3 months. Once reconstituted, use within 24 hours.

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.
