Clinical Overview

Epitalon (Ala-Glu-Asp-Gly) is a synthetic tetrapeptide modeled on pineal extracts investigated for its role in circadian regulation and cellular homeostasis. Research centers on epigenetic and neuroendocrine interfaces, including studies of sleep–wake biology, pineal–hypothalamic signaling, and biomarkers associated with replicative lifespan in vitro and in translational models.

Mechanism of Action

Pathways: Literature reports examine Epitalon’s effects on pineal and hypothalamic activity with downstream modulation of melatonin secretion and circadian gene programs (e.g., PER/CLOCK axes). In cell models, investigations include telomere biology (telomerase activity/readouts), genome maintenance signals, and oxidative-stress response.
Functional Notes: Ongoing studies probe redox homeostasis, mitochondrial efficiency, and proteostasis networks linked to cellular adaptation during replicative stress.

Research Applications

Circadian and sleep–wake regulation • Pineal–hypothalamic endocrine mapping • Telomere-related readouts in cell culture • Oxidative-stress and mitochondrial function assays • Exploratory models of cellular longevity and genomic maintenance.

Purity & Quality Assurance

Revitalized Health peptides are produced under cGMP-aligned conditions with pharmaceutical-grade inputs. Each Epitalon lot is confirmed at ≥99% purity by HPLC with identity verified via LC-MS/MS. Lots undergo appearance/solubility checks and microbial/endotoxin screening to research-grade specifications. Batch-level Certificates of Analysis document methods, parameters, and results for full traceability.

Storage & Stability

Store lyophilized vials at 2–8 °C, protected from light and moisture. Following reconstitution with bacteriostatic water, maintain at 2–8 °C and utilize within 20 days. Avoid repeated freeze–thaw cycles to preserve peptide integrity and target-engagement fidelity.

Mechanism & Testing

Identity: Epitalon (Ala-Glu-Asp-Gly; AEDG), a synthetic tetrapeptide based on pineal extract peptides (epithalamin).
Mode: Reported to modulate gene expression programs tied to circadian regulation and cellular stress responses; legacy studies describe normalization of melatonin secretion patterns and increased telomerase activity/TERT transcription in certain models and small human series. Additional findings include antioxidant pathway engagement and potential chromatin/DNA-protective effects in preclinical assays.
Analytics: Identity/purity by HPLC and LC-MS; peptide content & counter-ion profile; sterility/endotoxin where applicable; stability (accelerated/real-time). PD readouts (exploratory): salivary/serum melatonin rhythm, sleep metrics (actigraphy), oxidative-stress markers (8-oxo-dG, GSH/GSSG), leukocyte telomere/telomerase assays (qPCR/TRAP). Monitoring: local injection site tolerance (if parenteral), headache/fatigue, BP/HR as applicable.
