Product Name: Thymogen Pen 

Formulation: 2.6 mL pre-filled pen 

Clicks per Pen: 240 

Supplied with: 6 sterile needles (extras available) 

Active Ingredient: H-Glu-Trp-OH (Glutamyl-Tryptophan) – 20 mg per pen 

Concentration: 20 mg/2.6 ML 

Description 

Thymogen is a synthetic dipeptide with the chemical structure H-Glu-Trp-OH (L-Glutamyl-L-Tryptophan). It is a short- chain, tissue-specific bioregulator peptide originally developed in the former Soviet Union as part of the Khavinson peptide series. Thymogen mimics natural thymic factors and acts as a highly selective immunomodulatory signal. 

Mechanism of Action 

Thymogen binds to specific receptors on immune cells (primarily T-lymphocytes, NK cells, and monocytes/macrophages) and modulates intracellular signalling pathways. It normalizes gene expression patterns involved in: 

• T-cell differentiation and maturation 
• Cytokine production (e.g., IL-2, IFN-Y) 
• Antioxidant enzyme activity (superoxide dismutase, catalase) 
• Apoptosis regulation and cell survival 
• Restoration of thymic microenvironment function 

These effects result in balanced immune homeostasis, enhanced cellular immunity, reduced chronic inflammation, and accelerated recovery of immune competence after stress, infection, or age related decline. 

Indications & Usage 

Thymogen is used to support immune system function and resilience. It is indicated for: 

• Maintenance and restoration of immune competence 
• Assistance during periods of increased immune demand (e.g., recovery from illness, stress, or environmental exposure) 
• Support for age-related decline in thymic activity and T-cell function 
• General immune modulation and anti-aging support at the level of the immune system 

Contraindications & Warnings 

Do not use if you have: 

• Known hypersensitivity to any component of the formulation 
• Active autoimmune disease in acute phase 
• Uncontrolled malignancy or immunosuppressive therapy 
• Age under 18 years 
• Pregnancy or breastfeeding 

Warnings 

• Use only under medical supervision. 
• Not a substitute for standard medical treatment of infections, autoimmune disorders, or immunodeficiency. 
• Monitor for signs of immune overstimulation (e.g., fever, rash, joint pain) during initial use.
• Discontinue immediately and seek medical attention if unusual or severe symptoms occur. 

Dosage & Administration 

Subcutaneous injection only. 

• Low Dose (0.5 mg): 6 clicks daily- maintenance and general immune support (yields 40 doses) 
• Moderate Dose (1 mg): 12 clicks daily- moderate immune modulation and recovery support (yields 20 doses) 
• High Dose (2 mg): 24 clicks daily intensive immune restoration and targeted support (yields 10 doses) 
• Frequency: Once daily 
• Timing: Morning on an empty stomach or as directed by your healthcare provider 

Administration Instructions

1. Wash hands and prepare a clean surface. 
2. Attach a sterile needle. 
3. Dial the required number of clicks. 
4. Clean injection site (abdomen or upper thigh) with alcohol swab. 
5. Insert needle at 45-90° angle and inject slowly. 
6. Withdraw needle, dispose safely, and cap the pen. 
7. Rotate injection sites to minimize irritation. 
8. Always inspect solution before use: Do not inject if cloudy, discoloured, or containing particles. 

Side Effects 

Thymogen is generally well tolerated. Reported reactions are rare and mild, including: 

• Transient injection-site redness, itching, or mild swelling 
• Headache or light-headedness (usually resolves quickly) 
• Temporary fatigue or changes in energy levels during initial days 
• Rare mild flu-like symptoms (myalgia, low grade fever) during first week 
• If any severe or persistent symptoms occur, discontinue use and contact your healthcare provider immediately. 

Storage & Handling 

• Store either in refrigerator (fridge); never freeze or in a cool dry place (≤25-30°C / 77-86°F). 
• Keep pen capped and protected from light and heat. 
• After first use: Same storage conditions. 
• Keep out of reach of children. 
• Discard if expired or solution appears abnormal.
