Thymogen

aka Glu-Trp

Thymus-derived dipeptide bioregulator used as an immune modulator.

Educational explainer of a research peptide. Profiles in this section deliberately omit clinical-trial citations, dosing protocols, and purchase links. Not FDA-approved as a supplement; not a recommendation to use.

Overview

Thymogen is a synthetic Glu-Trp dipeptide derived from thymic peptide research, used as a non-specific immunomodulator.

Source
  • Manufactured in Russia as a pharmaceutical
Forms
  • Intramuscular injection
  • Intranasal solution

Mechanism of action

Stimulates T-cell maturation and balances cellular and humoral immunity, restoring blunted responses after injury, infection, or chemotherapy.

Pathways
  • · T-cell maturation
  • · Cytokine balance
  • · Phagocytic activation

How it acts on the body

Thymogen is one of the shortest active fragments derived from thymic peptide research. It is used clinically in Russia as an adjunct in chronic infections, post-surgical immune suppression, and chemotherapy recovery, with the goal of normalizing T-cell counts and function.

Compared with Thymalin (a larger thymic extract), Thymogen is a defined dipeptide, easier to synthesize and standardize, and its effects are oriented toward T-cell maturation specifically.

Hormonal & endocrine impact

How this peptide is reported to shift specific hormones and signaling molecules. Directionality reflects research literature and preclinical models, not clinical prescribing data.

Projected hormonal trajectory
Illustrative curves derived from reported direction of effect. Not measured patient data.

Curves are schematic shapes (sigmoid for increases/decreases, damped oscillation for modulation/stabilization) anchored to a 100% baseline. They communicate direction and tempo of change reported in research literature — not absolute hormone concentrations.

Pairing context

Often combined with
  • Nutritional support in catabolic states
    Immune restoration requires substrate.
Avoid combining with
  • Active autoimmune disease flare
    May amplify autoreactive immunity.
