02Mechanism of Action
Thymulin is a thymic nonapeptide whose biological activity in research models is strictly zinc-dependent — the zinc-bound form is the active species. It is studied for its role in thymocyte differentiation and T-cell development.
Research also examines its cytokine-modulating activity and its position in neuroendocrine-immune signaling networks.

05FAQ
What is Thymulin?
Thymulin is a zinc-dependent thymic nonapeptide studied for thymocyte differentiation and immunoregulation in research models. It is a research-use-only compound.
Why is zinc important for Thymulin?
Thymulin's research activity depends on bound zinc; the zinc-peptide complex is the biologically active form studied in the literature.
What is Thymulin's molecular weight?
Thymulin has a molecular weight of approximately 854.94 g/mol and CAS number 63958-90-7.
How should Thymulin be stored?
Thymulin ships lyophilized and should be handled per standard research-peptide practice — kept cold, protected from light and moisture, and reconstituted only for laboratory use. Cold-chain handling is used where required. For research use only.
Is Thymulin approved for human use?
No. Thymulin is sold strictly for laboratory research use only and is not a drug or supplement. It is not approved for human or veterinary use or consumption.
How is Thymulin tested at Ethos Bio?
Every Thymulin lot is independently verified by MZ Biolabs, a third-party analytical laboratory in Arizona, on a five-point panel — RP-HPLC purity, HPLC-MS identity, endotoxin (LAL), heavy metals, and sterility. A lot-specific certificate of analysis ships with the vial. See How We Test for the full methodology.
