Thymalin

Thymalin is a polypeptide preparation derived from calf thymus. Developed in Russia, it has been used for decades to support immune function and has shown potential anti-aging effects in long-term studies.

Mechanism of Action

Regulates the ratio of T-cell subpopulations, stimulates cellular immunity, and enhances phagocytosis. Also affects neuroendocrine regulation and may influence melatonin production.

Typical Dosage (Research)

Clinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance.

Intramuscular injection. Usually administered in short courses rather than continuously. Often combined with Epithalamin for anti-aging protocols.

Side Effects & Risks

Generally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated.

Most research from Russian studies. May not be appropriate for autoimmune conditions. Quality varies by source.

Who Uses Thymalin

Those seeking immune system support, individuals with age-related immune decline, longevity-focused biohackers.
