Thymalin vs Thymogen
An educational, source-based comparison of Thymalin and Thymogen — how each peptide works, what it's researched for, and what to know before going deeper.
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.
- Immunosenescence
- Recovery from infection in elderly cohorts
- Adjunct in chronic inflammatory conditions
- • Approved in Russia; not FDA-approved.
- • Mixture composition is not fully characterized.
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.
- Immunosenescence and age-related immune decline
- Post-infectious immune recovery
- Chronic fatigue and immune dysregulation
- • Russian bioregulator research; limited independent replication.
- • Not FDA-approved.
