Description
Uncompromising Quality Control
At Clear Peptides, quality is verified through independent third-party analytical testing conducted on each production batch. Every peptide is supplied with lot-specific Certificates of Analysis (COAs) confirming identity, purity, and batch consistency.
All materials undergo RP-HPLC purity analysis and ESI-MS identity confirmation before release. No lot ships without passing both tests.

Epithalon — Research Overview
Epithalon (Epitalon; Ala-Glu-Asp-Gly) is a synthetic tetrapeptide derived from the natural pineal peptide Epithalamin. It has been investigated extensively in gerontological research for its interactions with telomerase activity and telomere biology in cell culture systems.
Published research from multiple independent laboratories has examined Epithalon’s effects on telomerase expression, cell division capacity, and oxidative stress markers in aging cell models — making it a widely-used research compound in longevity biology investigations.
Research Context Reported in Scientific Literature
Epithalon has been evaluated in laboratory environments as described in peer-reviewed publications. Observations below are from controlled preclinical research models and do not constitute clinical evidence.
- Telomerase activity research: hTERT expression modulation and telomerase enzyme activity measurement in cell culture aging models
- Telomere length dynamics: Telomere attrition rate and length maintenance studies in replicatively senescent cell models
- Pineal gland peptide biology: Melatonin pathway interaction and pineal bioregulator function investigation in neuroendocrine models
- Oxidative stress markers: ROS levels, antioxidant enzyme activity, and oxidative DNA damage research in aged cell systems
- Circadian rhythm modulation: Interaction with circadian regulatory pathways and sleep-wake cycle associated gene expression research
These observations are exploratory and not conclusive.
Format & Handling
Supplied in sterile laboratory glass vials containing lyophilized peptide material. Reconstitution with bacteriostatic water or an appropriate laboratory solvent is required prior to research use.
Handling and storage should follow institutional laboratory protocols to maintain stability, purity, and analytical integrity. Store sealed vials at −20°C, protected from light and moisture.
