Pineal tetrapeptide profile for longevity, sleep, and circadian research. The Core PEPTIDE knowledge record describes Epithalon/Epitalon as a synthetic Ala-Glu-Asp-Gly tetrapeptide from pineal research, reviewed for telomerase, telomere, melatonin, sleep, circadian, and animal longevity models. Epithalon 25 mg is mapped to Core Peptide SKU ET25. Current storefront values use our product data: 25 mg x 10 vials / box, $90.00 USD per box. Core Peptide reference specs: 25 mg x 10 vials / 50 mg x 10 vials.

Research context

The Core PEPTIDE knowledge record describes Epithalon/Epitalon as a synthetic Ala-Glu-Asp-Gly tetrapeptide from pineal research, reviewed for telomerase, telomere, melatonin, sleep, circadian, and animal longevity models. Research typically reviews pineal peptide signaling, cellular aging markers, oxidative stress models, and telomere-related literature.

Commonly matched with

ET25 is commonly reviewed alongside 2S25, NJ500, NJ1000, MS10, and NAD+. Keep each combination tied to a defined research objective and lot record.

Compliance notice

ET25 is supplied for research use only. It is not for human or veterinary use, not for consumption, and statements on this page are reference context rather than medical claims.

Study design notes

Use the Core Peptide product knowledge record, current Core Peptide COA, and internal lab SOP to confirm identity, concentration, and endpoints before this material enters a study. The matched LPPeptide reference specification is 25 mg x 10 vials / 50 mg x 10 vials.

Core Peptide Handling Reference

Core PEPTIDE knowledge source: add 2.0 mL bacteriostatic water for 5 mg/mL. Reference amount is once daily 5,000 mcg for 20 days. At 5 mg/mL, 1 U equals 50 mcg.

Core PEPTIDE preparation pattern: use sterile technique, add diluent slowly down the vial wall, avoid foaming, roll gently until dissolved, label the preparation date, refrigerate at 2-8°C, and protect from light.

Preparation

Epithalon 25 mg ships as lyophilized powder. Reconstitution note: Core PEPTIDE knowledge source: add 2.0 mL bacteriostatic water for 5 mg/mL. Reference amount is once daily 5,000 mcg for 20 days. At 5 mg/mL, 1 U equals 50 mcg. Record the final concentration and preparation date in the study log.

Storage

Lyophilized: -20°C for long-term storage, or 2-8°C for routine refrigerated storage. Reconstituted: 2-8°C, use within 2-4 weeks, and avoid freeze-thaw cycles. Follow the most current lot-specific handling record whenever it is available.

Safety observations

Human safety data remains limited. Monitor protocol-defined biomarkers and avoid consumer-use framing.

Contraindications

Do not use ET10 outside qualified research workflows. Review the current SDS, COA, and protocol exclusions before handling.

Interaction review

Use caution with other longevity stacks, mitochondrial materials, or sleep/circadian study compounds.

Certificate of Analysis

Each Core Peptide lot should be confirmed against current batch documentation before shipment or study use. This product page keeps ET10 visible so the SKU can be matched to the active COA.
