Thymagen
Also known as: Thymogen
Thymus bioregulator peptide from the Khavinson series. Short peptide (2-4 amino acids) that targets specific tissue for gene expression regulation and organ health optimization.
Beginner Basics
Plain-English guide to Thymagen
What it does
This is a short chain of amino acids that researchers believe helps support your thymus gland, which is important for immune system function. Scientists typically study it to understand how it might help your body's immune cells work better as you age.
Typical dose
Researchers commonly use 10-20 micrograms once per day, starting at the lower dose to see how your body responds over 2-4 weeks.
When to inject
Best used in the morning, either under the tongue or as a small injection under the skin.
Storage
Keep the dry powder frozen at -20°C until you mix it. Once mixed with liquid, store it in the refrigerator between 2-8°C and keep it away from light.
First-timer tip
Start with the lower 10 microgram dose and wait 2-4 weeks before deciding if it's working for you, since this peptide is still mostly studied outside the Western world.

Side Effects
Mild redness, swelling, or itching at injection site. Usually resolves within hours. Rotate injection sites to minimize occurrence. Apply ice if needed.
Occasional mild headache reported in early use. Typically resolves within 24-48 hours. Ensure adequate hydration.
Transient mild fatigue or low-grade malaise as immune system adjusts. May indicate immune system response. Usually resolves within 1-2 weeks of continued use.
Severe allergic reactions are rare but possible. Seek immediate medical attention if experiencing difficulty breathing, severe swelling, or anaphylaxis. Discontinue use immediately.

Reconstitution Guide
Do not use saline or bacteriostatic saline, use only bacteriostatic water for reconstitution
Do not shake the vial vigorously; gentle swirling prevents peptide degradation
Discard immediately if the solution appears cloudy, discolored, or contains visible particles
Use within 30 days of reconstitution when stored at 2-8°C
Do not freeze the reconstituted solution; freezing may denature the peptide
Use the PeptideVolt reconstitution calculator for your exact concentration
Storage and Stability
Store lyophilized peptide at -20°C. Refrigerate after reconstitution (2-8°C). Protect from light.
Molecular and Pharmacological Data
Thymagen is a short peptide bioregulator (2-4 amino acids) derived from thymus tissue that is believed to support thymus gland function and immune cell development. It may work by promoting tissue-specific gene expression patterns that enhance T-cell maturation and immune regulation, particularly in aging or immunocompromised states. The peptide is thought to act as a signaling molecule that restores age-related decline in thymic function.
