Thymulin — research data
Research-literature reference data, NOT patient instructions. Not for human use. Consult a licensed clinician for any human application.
Overview
About Thymulin
Mechanism of action
Nonapeptide thymic hormone secreted by thymic epithelial cells; its biological activity is strictly zinc-dependent (zinc must be bound for the peptide to be active). Promotes T-cell differentiation and NK-cell development and helps balance cytokine signaling; in animal models it sensitizes end-organs to hormone signaling (e.g. greater target-hormone output when combined with ACTH or hCG). Falling thymulin activity is among the earliest measurable markers of zinc deficiency, before serum or red-cell zinc drop.
Safety profile
Human safety data is sparse. Activity is strictly zinc-dependent, so effects are inseparable from zinc status. Generally low reported toxicity in animal models, but it should be treated as experimental. Research-use only; not for human consumption. · Endogenous zinc-dependent thymic nonapeptide (FTS); low toxicity in animal models and a benign physiologic profile, but human safety/PK data is sparse and there is no established dose. Activity is inseparable from zinc status; treat as experimental.

Studies & key findings
- Thymulin is a zinc-dependent nonapeptide thymic hormone (also called FTS, facteur thymique sérique). Its biological activity REQUIRES bound zinc — without zinc the peptide is inactive — and declining thymulin activity is one of the earliest measurable markers of zinc deficiency, appearing before serum or red-cell zinc fall.
- It promotes T-cell differentiation and NK-cell development and helps balance cytokine signaling. In animal models it 'sensitizes' end-organs to hormone signaling (e.g. greater target-hormone output when paired with ACTH or hCG), forming a link between immune status and the endocrine system.
