# Thymalin > Thymic peptide complex researched for immune restoration in aging. Source: https://peptides.cafe/peptide/thymalin Category: Immune · Bioregulator Tag: Immune · Longevity ## Mechanism A polypeptide complex extracted from calf thymus, studied as an immune bioregulator. Research suggests restoration of T-cell function and thymic activity in aged and immunocompromised cohorts. ## Research areas - Immunosenescence - Recovery from infection in elderly cohorts - Adjunct in chronic inflammatory conditions ## Common research protocols - Cyclic intramuscular use: Short courses in Russian clinical protocols. ## Study summaries - "Thymalin in geriatric patients: long-term outcomes" — Advances in Gerontology (2014): Multi-year follow-up reported reduced morbidity and improved immune markers. ## Considerations - Approved in Russia; not FDA-approved. - Mixture composition is not fully characterized. ## Disclaimer Educational content only.
