Epithalamin vs Thymalin

A detailed comparison to help you understand the differences and choose the right peptide for your research goals.

Epithalamin

Epithalamin is a natural peptide extract from the pineal gland. It is the precursor compound from which the synthetic Epitalon was derived. Known for anti-aging and telomerase-activating properties.

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.

Side-by-Side Comparison

AspectEpithalaminThymalin
MechanismSimilar to Epitalon, it stimulates telomerase production and may help maintain telomere length. Also regulates melatonin synthesis and circadian rhythms.Regulates the ratio of T-cell subpopulations, stimulates cellular immunity, and enhances phagocytosis. Also affects neuroendocrine regulation and may influence melatonin production.
Typical DosageResearch dosing: 10-20mg daily for 10-20 day cycles. Often administered 1-3 times per year in long-term protocols.Clinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance.
AdministrationIntramuscular or subcutaneous injection. Natural extract may have more variable composition than synthetic Epitalon.Intramuscular injection. Usually administered in short courses rather than continuously. Often combined with Epithalamin for anti-aging protocols.
Side EffectsGenerally well-tolerated. May affect sleep patterns. Less characterized than synthetic Epitalon.Generally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated.
