How to Store Epitalon: Temperature, Shelf Life & Handling

Storage requirements for Epitalon follow from what the molecule actually is — synthetic tetrapeptide (ala-glu-asp-gly). The conditions below reflect that chemistry rather than generic peptide guidance.

Synthetic tetrapeptide (Ala-Glu-Asp-Gly)Cellular LongevityCircadian & Sleep

In plain English

Freezer for the powder, fridge once mixed, three to four weeks. Honestly, this is the least demanding compound here. It has no light-sensitive or oxygen-sensitive parts at all, so a sound seal and refrigeration genuinely cover it.

What Epitalon actually is

Epitalon 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.

Research-grade Epitalon

Third-party tested by HPLC and LC-MS, ≥99% purity, with a Certificate of Analysis on every order. Ships across Canada.

Storage conditions for Epitalon

Lyophilized powderSealed at -20 °C; short 2–8 °C periods are entirely acceptable for a molecule this small and simple.
ReconstitutedRefrigerate at 2–8 °C. No methionine, cysteine, or tryptophan — light protection is not the priority it is for other compounds here.
Working windowCommonly worked with for 3–4 weeks at 2–8 °C.

Why these conditions, specifically

Epitalon's one genuine chemical liability is the Asp-Gly isomerisation site. Because isomerisation does not change mass, it is invisible to LC-MS and shows only on the chromatogram — the same analytical blind spot that affects DSIP.

The main route to be aware of: aspartate-glycine isomerisation — the Asp-Gly motif is among the most isomerisation-prone sequences in peptide chemistry, and Epitalon contains it.

All 3 degradation routes for Epitalon

Freeze–thaw

Highly tolerant. A four-residue peptide has essentially no structure to disrupt, making this one of the more freeze-tolerant compounds in the catalogue.

What Epitalon is studied for

Telomerase activation

The most-cited claim in the Epitalon literature, examined in cell-culture models.

Pineal and melatonin rhythm

Follows from its Epithalamin origin; studied for effects on circadian signalling in animal models.

Ageing models

A long-running Russian research programme examined lifespan endpoints in rodent models.

Peptide bioregulator concept

Epitalon is the flagship of Khavinson's "peptide bioregulator" framework, a distinct research tradition worth understanding as context.
