Thymalin
Overview
A peptide bioregulator originally extracted from bovine thymus gland, consisting of a mixture of polypeptides that modulate immune function. Thymalin restores T-cell mediated immunity by promoting T-lymphocyte maturation and differentiation in the thymus.
Mechanism of Action
It also normalizes the ratio of T-helper to T-suppressor cells and enhances phagocytic activity of neutrophils and macrophages.
Research Summary & Key Findings
Long-term clinical studies by Khavinson showed restoration of immune function in elderly patients and potential lifespan extension. Research in Russia demonstrated improved immune parameters in immunocompromised patients. Studies suggest synergistic effects with Epithalon on aging biomarkers (Khavinson & Morozov, Neuroendocrinology Letters, 2003).
Clinical Status
Thymalin is in the investigational stage. While preclinical and early-phase data exist, it has not received regulatory approval for clinical use in the United States.

View detailsNo lawful pathway today
Thymalin is not FDA-approved and does not currently have a lawful prescription or compounding pathway in the United States, so there is nothing for us to sell you here and no consultation to book. That can change: eight peptides moved back to a lawful pathway in February 2026.
