Thymosin Alpha-1 vs Epigen
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Thymosin Alpha-1
Thymosin Alpha-1 is a peptide naturally produced by the thymus gland that plays a crucial role in immune system modulation. It is approved in over 35 countries for various conditions including hepatitis B and C.

| Aspect | Thymosin Alpha-1 | Epigen |
|---|---|---|
| Mechanism | Enhances T-cell function and maturation, stimulates dendritic cell activity, and modulates cytokine production. Promotes the differentiation of stem cells into mature T lymphocytes. | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. |
| Typical Dosage | Clinical dosing typically ranges from 1.6mg to 6.4mg administered subcutaneously 2-3 times weekly. Research protocols may vary. | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. |
| Administration | Subcutaneous injection. Often used in cycles or as part of comprehensive immune support protocols. | Primarily topical application for skincare. Research may use other routes for systemic effects. |
| Side Effects | Generally well-tolerated. Rare side effects include injection site reactions, mild flu-like symptoms, and temporary fatigue. | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. |
