# Thymogen > Dipeptide bioregulator for immune system modulation. Source: https://peptides.cafe/peptide/thymogen Category: Immune · Bioregulator Tag: Immune · Bioregulator ## Mechanism A synthetic dipeptide (Glu-Trp) in the Khavinson bioregulator family. Research suggests modulation of thymic and immune cell gene expression, supporting T-cell maturation and innate immune response in aged models. ## Research areas - Immunosenescence and age-related immune decline - Post-infectious immune recovery - Chronic fatigue and immune dysregulation ## Common research protocols - Cyclic subcutaneous use: Short subcutaneous courses in Russian gerontology and immune protocols. ## Study summaries - "Thymogen and immune restoration in elderly" — Advances in Gerontology (2016): Improved T-cell counts and immune response markers in aged cohorts. ## Considerations - Russian bioregulator research; limited independent replication. - Not FDA-approved. ## Disclaimer Educational content only.
