Epithalon Handling Guide: Common Mistakes to Avoid
Most handling advice for research peptides is written generically. The practices below are the ones that specifically matter for Epithalon — including the mistakes it is unusually easy to make with this compound.
Overview
Do not over-engineer this one. Refrigeration and a sound seal are sufficient. The only real caution is not storing mixed solution for months, since the internal rearrangement is slow but continuous.
What Epithalon actually is
Epithalon is the smallest molecule in this library — just four amino acids. It was distilled from an extract of the pineal gland studied in the Soviet Union from the 1970s, representing an attempt to find the shortest sequence that carried the activity of a complex tissue extract.
Supplied for laboratory research use only — not for human or animal use.

Bench practices for Epithalon
- Do not over-engineer storage for this compound — refrigeration and a sound seal are genuinely sufficient.
- Avoid prolonged storage of reconstituted solution, since Asp-Gly isomerisation is slow but cumulative.
- Verify the analytical method behind any purity figure, as short polar peptides are easy to under-resolve.
The chemistry behind these practices
- Aspartate-glycine isomerisation — the Asp-Gly motif is among the most isomerisation-prone sequences in peptide chemistry, and Epithalon contains it.
- Rapid aminopeptidase cleavage in biological media, a consequence of its short unprotected sequence.
- Adsorption is minimal given the small size and net negative charge.
