How to Store Epithalon: Temperature, Shelf Life & Handling
Storage requirements for Epithalon follow from what the molecule actually is — synthetic tetrapeptide (ala-glu-asp-gly). The conditions below reflect that chemistry rather than generic peptide guidance.
Overview
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 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.

Storage conditions for Epithalon
Why these conditions, specifically
Epithalon'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 Epithalon contains it.
All 3 degradation routes for EpithalonFreeze–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 Epithalon is studied for
The most-cited claim in the Epithalon literature, examined in cell-culture models.
Follows from its Epithalamin origin; studied for effects on circadian signalling in animal models.
A long-running Russian research programme examined lifespan endpoints in rodent models.
Epithalon is the flagship of Khavinson's "peptide bioregulator" framework, a distinct research tradition worth understanding as context.
