Thymalin is a classic thymus-derived immunomodulator — not a single peptide but a standardised polypeptide fraction extracted from calf thymus. Developed in Russia in the 1970s, it is studied for restoring immune balance, especially with aging.
How Thymalin works
Thymalin is a mixture of low-molecular-weight thymic peptides. Rather than blanket-stimulating the immune system, it is reported to help restore and normalise T-cell immunity and immune balance. Its constituent short peptides are proposed to regulate gene expression, cytokine synthesis and immune-cell differentiation. It has been studied mainly in immunodeficiency, infection recovery and age-related immune decline.
What the research shows
- Longevity study (Khavinson & Morozov, 2003). A 6–8-year study in older adults reported that annual thymic/pineal peptide courses reduced mortality versus controls (single research-school data).
- Immunocorrection review (Khavinson et al., 2021). Reviewed thymalin’s immunomodulatory use and the molecular activity of its short peptides.
- Severe COVID-19 (Khavinson et al., 2021). A randomised single-blind trial reported faster recovery of immune markers in older severe-COVID patients.
Candour: thymalin’s evidence base is mostly Russian clinical and preclinical work from a single research school, with limited independent Western replication; it is a thymus extract, so it has no single molecular formula, weight or CAS. Use belongs under a physician’s guidance.
