What is Epitalon?
Epitalon (Epithalon — AEDG synthetic tetrapeptide (pineal gland)) is a 4-amino acid synthetic tetrapeptide (Ala-Glu-Asp-Gly). Synthetic pineal tetrapeptide activating hTERT (telomerase reverse transcriptase) expression in somatic cells, reducing oxidative stress markers (MDA, SOD, catalase), and restoring melatonin circadian amplitude in aged models. Khavinson longevity studies: 13–25% lifespan extension in rodents and extended human cohort data.

Frequently Asked Questions
How do I reconstitute this peptide?
Add 1–2mL bacteriostatic water to the lyophilized Epitalon (AEDG tetrapeptide) vial. Epitalon is a very small tetrapeptide and dissolves almost instantly to a clear, colourless solution. Swirl gently.
How should this peptide be stored?
Store lyophilized at −20°C. Reconstituted: 2–8°C for up to 28 days. As a tetrapeptide, Epitalon is quite stable. Avoid direct light exposure of reconstituted solution.
What purity is this QSC compound and how is it verified?
QSC Epitalon (Ala-Glu-Asp-Gly) is ≥99% pure by HPLC with MS-confirmed tetrapeptide identity on every batch. COA is published on the product page and verifiable at verify.janoshik.com.
