Thymulin vs MGF (Mechano Growth Factor)
A detailed comparison to help you understand the differences and choose the right peptide for your research goals.
Thymulin
Thymulin (Facteur Thymique Sérique) is a zinc-dependent nonapeptide hormone produced by thymic epithelial cells. It plays important roles in T-cell differentiation and immune system maturation.
Full details →MGF (Mechano Growth Factor)
MGF (Mechano Growth Factor) is a splice variant of IGF-1 that is produced locally in muscle tissue in response to mechanical stress. The non-PEGylated form has a very short half-life.

| Aspect | Thymulin | MGF (Mechano Growth Factor) |
|---|---|---|
| Mechanism | Requires zinc for biological activity. Promotes T-cell differentiation, modulates cytokine production, and influences neuroendocrine function. Levels decline significantly with age. | Activates muscle satellite cells (stem cells) and promotes their proliferation without differentiation, priming them for fusion with existing muscle fibers during repair and growth. |
| Typical Dosage | Research protocols vary. Often studied alongside zinc supplementation. Typical research doses in the microgram range. | Due to extremely short half-life (minutes), typical protocols use 100-200mcg injected directly into target muscles immediately post-workout. |
| Administration | Subcutaneous or intramuscular injection in research settings. Requires adequate zinc status for activity. | Intramuscular injection into trained muscles within minutes of workout completion. Must be used immediately after reconstitution due to instability. |
| Side Effects | Limited data on exogenous administration. Theoretical effects on immune function require monitoring. | Injection site soreness, potential hypoglycemia, localized swelling. Short half-life limits systemic effects. |
