Thymalin vs Epigen
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Thymalin
Thymalin is a polypeptide preparation derived from calf thymus. Developed in Russia, it has been used for decades to support immune function and has shown potential anti-aging effects in long-term studies.
Full details →Epigen
Epigen is a member of the epidermal growth factor (EGF) family. It plays roles in skin regeneration and has been studied for wound healing and anti-aging applications.
Full details →Side-by-Side Comparison
| Aspect | Thymalin | Epigen |
|---|---|---|
| Mechanism | Regulates the ratio of T-cell subpopulations, stimulates cellular immunity, and enhances phagocytosis. Also affects neuroendocrine regulation and may influence melatonin production. | Binds to and activates the EGF receptor (EGFR), promoting cell proliferation, migration, and differentiation. Involved in skin homeostasis and repair processes. |
| Typical Dosage | Clinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance. | Topical: Typically used at low concentrations (ppm to low %) in cosmetic formulations. Research applications vary. |
| Administration | Intramuscular injection. Usually administered in short courses rather than continuously. Often combined with Epithalamin for anti-aging protocols. | Primarily topical application for skincare. Research may use other routes for systemic effects. |
| Side Effects | Generally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated. | Topical use generally well-tolerated. Theoretical concerns about promoting cell proliferation. |
