Overview
Thymogen is a synthetic dipeptide (glutamyl-tryptophan) developed as a simplified, defined follow-on to thymus extract preparations. It is commonly cited in the Russian research literature for context on immune regulation and is described in intranasal and injectable forms. As with related thymic peptides, most supporting data are non-Western and independent verification is limited.
How it’s thought to work
- Reported to influence T-cell maturation and immune cell activity.
- Appears to modulate cytokine and inflammatory responses.
- Studied as a synthetic analog of thymic immunoregulatory peptides.
- Proposed to help normalize immune parameters rather than broadly stimulate them.
Researched uses
- Immune support during infection (research reports)
- Recovery from immune suppression in Russian studies
- Adjunct research in inflammatory conditions
- Mucosal immunity via intranasal formulations
Commonly cited protocol
| Typical dose | ~100 mcg per day |
|---|---|
| Frequency | Once daily over short courses in reported use |
| Route | Intramuscular injection or intranasal (research) |
| Notes | Also described as a nasal solution in some formulations. |
Reconstitution
Commonly a 5 mg vial; 5 mg in 2 mL gives 2.5 mg/mL, so a 100 mcg dose is about 4 units on a U-100 syringe.
Thymogen dosage calculator
The calculator below is pre-filled with Thymogen’s commonly cited vial size and dose. Adjust the vial amount, bacteriostatic water, or dose to match your own vial — it will show the exact insulin-syringe units to draw, the concentration, and how many doses the vial holds.
Add 2 mL of bacteriostatic water to your 5 mg vial. That gives you about 50 doses of 100 mcg. For each dose, draw 4 units into a 100-unit insulin syringe.

Cautions
- Not FDA-approved; treated as a research chemical outside its origin countries.
- Evidence is largely non-Western and limited in scope.
- Long-term human safety data are lacking.
- Source purity varies.
