Description
Thymulin is a nine-amino-acid hormone produced by the thymus gland and one of the classic peptides of immunology research. Limitless Life Nootropics supplies it as a 10mg lyophilized vial, made in the USA.
What Is Thymulin?
Originally described in the 1970s as facteur thymique sérique (FTS), the peptide is secreted by thymic epithelial cells. Its sequence is pGlu-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn, and it requires a bound zinc ion to become biologically active—a feature that links zinc status directly to its activity.
Research has examined its role in T-cell differentiation, natural killer cell activity and cytokine regulation. It also appears to communicate with the neuroendocrine system, and studies have investigated its anti-inflammatory and pain-modulating effects in animal models. Like other thymic factors, its levels decline with age as the thymus shrinks.
Each Premium lyophilized vial contains 10mg.
Key Research Areas
The scientific literature describes this peptide across several areas of investigation:
- T-lymphocyte differentiation and maturation
- Zinc-dependent peptide activity
- Neuroendocrine–immune interactions
- Inflammatory pain models
- Thymic aging (involution) research
Researchers can review peer-reviewed studies on this compound through the National Library of Medicine (PubMed) database.
