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.
Mechanism of Action
Requires zinc for biological activity. Promotes T-cell differentiation, modulates cytokine production, and influences neuroendocrine function. Levels decline significantly with age.
Dosage Overview
Dose Range
100 mcg – 400 mcg
Route
subcutaneous
Frequency
1x daily
Cycle Length
4–8 weeks
Reconstitution
Typical Dosage (Research)
Research protocols vary. Often studied alongside zinc supplementation. Typical research doses in the microgram range.
Subcutaneous or intramuscular injection in research settings. Requires adequate zinc status for activity.
Considerations for Men & Women
Women: Zinc-dependent thymic hormone. No established sex-specific differences in immune effects. May be relevant for age-related immune decline in both sexes.
Men: Same considerations. Limited clinical data on exogenous administration for both sexes.
Individual responses vary. These notes reflect general trends from research literature and are not medical advice.
