Thymogen (Thymagen)
EW Dipeptide · Thymus Immune Bioregulator
Overview
Thymogen (EW dipeptide) is a Khavinson bioregulator consisting of glutamic acid and tryptophan, originally isolated from calf thymus extracts (Thymalin) in the late 1980s. Developed by Professor Vladimir Khavinson, it has been registered in Russia since 1990 in multiple forms including injectable solution, nasal spray, and topical cream. Thymogen modulates both humoral and cellular immunity, activates T-cell differentiation, and has demonstrated geroprotective (anti-aging) and antitumor activities in research studies.
Thymogen works through multiple immunomodulatory mechanisms: (1) activates T-cell differentiation and T-cell recognition of peptide-MHC complexes, (2) induces changes in intracellular cyclic nucleotide composition, (3) activates neutrophilic chemotaxis and phagocytosis, (4) normalizes T-lymphocyte concentrations and ratios (CD3+, CD4+, CD8+), (5) stimulates production of immunoglobulins (IgA, IgG, IgE, IgM), and (6) enhances lymphocyte differentiation receptor expression. Research suggests Thymogen may interact specifically with the AACG DNA sequence, affecting gene expression. The peptide is rapidly distributed to thymus, lymph nodes, liver, adrenals, and kidneys.
Modulates both humoral and cellular immune responses for balanced immunity.
Activates T-cell differentiation and normalizes CD3+, CD4+, CD8+ populations.
Stimulates production of IgA, IgG, IgE, and IgM antibodies.
Studied for improving surgical outcomes through immune support.

FAQs
What's the difference between Thymogen (EW dipeptide) and Thymalin (extract mixture)?
Thymogen is a single, pure dipeptide (Glu-Trp) isolated from Thymalin extracts. Thymalin is the complete mixture containing multiple peptides (KE, EW, EDP). Thymogen offers standardized dosing and stability, while Thymalin provides broader synergistic effects - both are compatible and sometimes used together.
Can Thymogen be taken orally or must it be injected?
Thymogen is available in multiple forms - oral capsules, injectable solution, nasal spray, and topical cream (all registered in Russia). The dipeptide's small size allows reasonable oral bioavailability via capsules, making it more convenient than injectable-only bioregulators.
How do Thymogen and Epitalon compare for anti-aging and lifespan extension?
Both are Khavinson anti-aging peptides with different targets. Thymogen focuses on immune rejuvenation and tumor suppression, while Epitalon targets pineal/endocrine aging. Combined use showed robust lifespan increases and antitumor activity in research models - they're synergistic rather than redundant.
Is Thymogen banned in sports like other immune peptides?
Thymogen is not explicitly listed as banned by WADA since it's not widely used in sports, but as a performance-enhancing immune modulator, it would likely be prohibited if tested. Check with your sport's governing body, but assume risk if subject to anti-doping testing.
