- The following table clarifies the relationship between Epithalamin and Epithalon across chemical, historical, and practical sourcing dimensions—highlighting that while names differ, the underlying peptide remains identical.
- Amino Acid Sequence
- Ala-Glu-Asp-Gly
- Identical tetrapeptide structure—no sequence variation between nomenclature systems
- Molecular Weight
- 390.35 g/mol
- Mass spectrometry confirms identical molecular formula C14H22N4O9 regardless of product naming
- Historical Origin
- Russian transliteration from Cyrillic 'Эпиталамин' (1980s Soviet research literature)
- Western transliteration adopted in English-language journals during 1990s citation
- Dual nomenclature stems from transliteration differences, not chemical distinctions—both trace to Khavinson's original synthesis
- Primary Mechanism
- hTERT gene upregulation leading to telomerase activation; pineal peptide bioregulation restoring circadian melatonin synthesis
- No mechanistic difference—biological pathway activation identical across nomenclature
- Supplier Preference
- Common in Russian and Eastern European peptide catalogs; retained by suppliers serving institutions familiar with original Khavinson nomenclature
- Dominant in Western research suppliers and North American peptide distributors
- Naming preference reflects supplier geography and target market, not product differentiation—verify sequence via COA rather than relying on product name
- Storage Stability
- Lyophilized powder stable 24–36 months at −20°C; reconstituted peptide degrades within 28 days at 2–8°C
- Storage parameters determined by peptide structure, not nomenclature—identical stability profiles across both names
