What is Epithalon?
Epithalon is a tetrapeptide — alanine, glutamic acid, aspartic acid, glycine. Four residues, which makes it one of the shortest chains in the range.
Classification
| Type | Peptide |
| Chain length | 4 amino acid residues |
| Family | Pineal peptide analogue |
| Origin | Developed in Russia by Vladimir Khavinson, from the late 1980s |
| Supplied as | Lyophilised powder in a sealed vial |
It came out of a Soviet and then Russian line of research into short peptides derived from tissue extracts. The synthetic tetrapeptide was designed as a defined-sequence successor to epithalamin, a pineal gland extract, replacing an uncharacterised mixture with a single known molecule.
Where it sits by length
At 4 residues, Epithalon is one of the shortest chains it is still conventional to call a peptide. The boundary is a convention, not a rule of chemistry — chains up to roughly fifty residues are generally called peptides.
What this page does not cover
Nothing here describes what Epithalon does, what it is used for, or whether it is safe. We publish analytical results and ship parcels; we give no guidance on dosing, preparation or use, and that applies to our reference pages as much as to the product pages. The person to ask about any of that is a registered prescriber.
Where it came from
Epithalon is a four-residue synthetic peptide derived from epithalamin, a pineal-gland extract studied in the Soviet Union from the 1970s onward.
The 1990s — Saint Petersburg, Russia. When was Epithalon created?
