Epithalon vs Thymalin: Head-to-Head Comparison
Both are Russian-developed peptides studied for anti-aging. Epithalon (Epitalon) is a tetrapeptide that activates telomerase and is derived from epithalamin (pineal extract). Thymalin is a thymus-derived peptide that modulates immune function. Both were developed by Prof. Vladimir Khavinson.
Side-by-Side Comparison
| Dimension | Epithalon | Thymalin |
|---|---|---|
| Evidence Level | Russian clinical studies; Khavinson's telomerase research | Russian clinical studies; decades of use in Russia |
| FDA Status | Not approved in US/EU | Not approved in US/EU; used clinically in Russia |
| Mechanism | Telomerase activation, pineal gland melatonin regulation | Thymic immune modulation, T-cell maturation support |
| Primary Use | Anti-aging, telomere lengthening, circadian rhythm | Immune restoration, particularly in aging or immunocompromised |
| Side Effects | Minimal reported | Minimal reported |
| Anti-Aging Mechanism | Telomere maintenance (cellular aging) | Immune system rejuvenation (immunosenescence) |
Peptide Overviews
Epithalon (Epitalon)
CPreclinicalEpithalon (also spelled Epitalon or Epitalone) is a synthetic tetrapeptide based on the natural peptide epithalamin, produced by the pineal gland. Research by Vladimir Khavinson suggests it may activate telomerase and extend cellular lifespan.
Thymalin
CPreclinicalThymalin is a synthetic dipeptide (glutamyl-tryptophan) originally derived from calf thymus extract. Developed by Vladimir Khavinson in Russia, it is used there for immune modulation.
