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.
Dosage Overview
Dose Range
5 mg – 10 mg
Route
intramuscular
Frequency
1x daily
Cycle Length
1–2 weeks
Reconstitution
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.
Considerations for Men & Women
Women: Thymic peptide for immune modulation. No established sex-specific differences. Short cycling protocols. Standard pregnancy precautions.
Men: Same immune support profile. No sex-specific dose adjustments.
Individual responses vary. These notes reflect general trends from research literature and are not medical advice.

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.
