Epitalon vs Thymalin

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

Epitalon

Epitalon (Epithalon) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. It is primarily studied for its effects on telomerase activation.

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

AspectEpitalonThymalin
MechanismStimulates telomerase production, which can lengthen telomeres on DNA strands. May also regulate melatonin production 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 DosageTypical protocols: 5-10mg daily for 10-20 days, repeated 2-3 times per year.Clinical protocols: 5-20mg daily intramuscularly for 3-10 days. Often cycled 1-2 times per year for maintenance.
AdministrationSubcutaneous or intramuscular injection. Usually administered in cycles rather than continuously.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 initially.Generally well-tolerated. May cause injection site reactions or temporary flu-like symptoms as immune function is modulated.
