About Thymulin
- What it is
- Thymulin, historically called serum thymic factor, is a nonapeptide produced by the thymus that requires bound zinc to become biologically active. It helps drive T-cell maturation and modulates immune and inflammatory signaling, and its activity falls with age and zinc deficiency. Thymulin is not approved by the FDA and remains a research compound, with most human data involving indirect restoration through zinc.
- How it works
- It is a zinc-dependent thymic nonapeptide that promotes T-cell differentiation and modulates cytokine and neuroendocrine signaling.
