Short synthetic peptides
Epitalon research peptide
Epitalon is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. It was designed from the composition of epithalamin, a polypeptide extract of the pineal gland, and is one of the shortest peptides in regular laboratory use.
For in-vitro laboratory research only. Not for human or veterinary use.

Frequently asked questions
What is Epitalon?
Epitalon is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. It was designed from the composition of epithalamin, a polypeptide extract of the pineal gland, and is one of the shortest peptides in regular laboratory use.
How is each Epitalon lot tested?
Every lot is tested at an ISO/IEC 17025 accredited third-party laboratory against an eight-assay panel: HPLC-UV purity, quantitative net peptide content, LC-MS identity, appearance, a fentanyl screen, heavy metals by ICP-MS, sterility by PCR, and endotoxin by LAL. The certificate is published before the lot ships.
How do I verify the certificate for my Epitalon vial?
Scan the QR code on the vial label to open the certificate for that exact lot, or search the lot number in the North Wall COA library.
Is Epitalon for human use?
No. North Wall sells this compound solely for in-vitro laboratory research by qualified researchers aged 21 and over. It is not for human or veterinary use, and North Wall does not provide use, preparation, or dosing guidance.
