Khavinson tetrapeptide.
Epitalon is a synthetic tetrapeptide developed by Vladimir Khavinson's group as part of a program to identify short peptide bioregulators from endocrine gland extracts. Derived from pineal gland research, it is one of the most widely studied of the "Khavinson peptides." Supplied as research-grade material with 3rd-party HPLC verification and full Certificate of Analysis per lot.

Published work (primarily Russian-language literature) describes effects on telomerase activity, telomere length, and circadian regulation in cell culture and animal models. The proposed mechanism involves direct binding to specific DNA sequences, modulating gene expression. These effects have not been independently validated in extensive Western literature.
Widely available as a research compound. The Khavinson peptide family more broadly has an extensive Russian research literature but limited validation in other countries. Not FDA-approved.
The above summarizes published research literature. This is not medical advice, a protocol, or a recommendation for use. This compound is supplied for laboratory research only.
Epitalon is a 4-residue peptide with molecular formula C14H22N4O9 and molecular weight of approximately 390.4 Da.
The full structural data and release specifications are in the Compound Profile section above. Every lot ships with an independently verified Certificate of Analysis.
Each lot is independently verified by a 3rd-party analytical laboratory (STERIS Labs, Alcami Analytical, or equivalent) before release. Release specification is HPLC purity ≥ 99.5% (typical > 99.8%), mass spectrometry identity match within ±0.5 Da, water content < 5.0% Karl Fischer, and endotoxin < 0.25 EU/mL by LAL (USP <85>).

All compounds ship at ambient temperature in discreet, tamper-evident packaging. Lyophilized peptide powder is stable at room temperature for typical transit windows, which is why research-grade vendors ship this way. Tracked; signature not required.
Store unopened lyophilized product at 2–8°C protected from light. Once reconstituted, most peptides are stable at 2–8°C for approximately 28 days (compound-dependent).

All PeptideBros compounds are sold strictly as chemical reference materials for in-vitro laboratory research. They are not for human consumption.
HPLC-verified. Mass-spec confirmed. Ambient-stable transit. The paperwork other vendors hope you never ask for.
