Thymalin
The Thymic Peptide for Immune Rejuvenation
01
Overview
Thymalin is a natural polypeptide complex isolated from calf thymus glands. Developed in Russia alongside Epithalamin, it has been studied for decades as a systemic bioregulator. Research focuses on its ability to restore thymic function, rejuvenate immune competence in aged organisms, and normalize neuroendocrine balance, with human longevity trial data available.
02
Mechanism of Action
Thymalin contains multiple thymic peptides including Thymalin-A1 through A4 that stimulate differentiation and proliferation of T-lymphocyte precursors. It activates IL-2 production and T-helper cell function while reducing the Th1/Th2 imbalance characteristic of immunosenescence.
03
Research Highlights
6-year human trial by Khavinson and Morozov shows 2.0-2.4× reduction in mortality in elderly patients
Immune studies show restoration of T-cell counts and natural killer cell function in aged subjects
Neuroendocrine studies demonstrate normalization of melatonin and cortisol rhythms
04
