Description

Premium Epitalon – 10mg Research Grade Peptide UK

Product Overview

If you are looking for research-grade Epitalon in the UK, Cocer Peptides supplies a high-purity 10mg presentation of this synthetic tetrapeptide. Also known as Epithalon or AEDG, it is a four-amino-acid peptide with the sequence Ala-Glu-Asp-Gly, first synthesised based on the amino acid composition of Epithalamin, a bovine pineal gland extract, as documented by Creative Peptides. The compound is structurally composed of alanine, glutamic acid, aspartic acid, and glycine, with a molecular weight of 390.35 Da, according to the NIH PubChem database.

Researchers investigating this Epitalon peptide typically focus on its reported telomerase-activating properties. A 2025 study published in Springer’s Biogerontology journal demonstrated that it increased telomere length in human cell lines through telomerase upregulation or alternative lengthening of telomeres (ALT) activity. This independent replication from a Western laboratory represents a significant development in the research literature, though the study’s authors note that telomerase activation in cultured cells does not establish that the peptide activates telomerase in vivo in adult human tissues.

Important Notice: This product is supplied strictly for laboratory research use only and is not intended for human or veterinary use. Epitalon has not been approved by the FDA or most Western regulatory agencies and exists in a regulatory gray zone in most countries. The FDA reviewed it through the 2026 PCAC compounding process, which does not constitute therapeutic approval. This product is not authorised by the Medicines and Healthcare products Regulatory Agency (MHRA) as a medicine.

Mechanism of Action

Telomerase Activation and Telomere Elongation

The most extensively studied mechanism of this Epitalon peptide involves telomerase activation. Research published in Springer’s Biogerontology journal (2025) examined treatment in human cell lines, including breast cancer cells (21NT, BT474), normal fibroblasts (IBR.3), and epithelial cells (HMEC). The study found that it extended telomere length through hTERT/telomerase upregulation in normal cells and alternative lengthening of telomeres in cancer cell lines. A separate 2025 study published via ScienceDirect in Life Sciences replicated these findings in bovine cumulus-oocyte complexes, demonstrating that the compound activated telomerase, improved oocyte maturation rate, and enhanced post-thaw blastocyst development.

Chromatin Activation and Gene Expression

A 2003 study published in Neuroendocrinology Letters examined the effect of synthetic Epitalon on ribosomal gene activity in cultured lymphocytes from persons aged 76-80 years. The results demonstrated that it induced activation of ribosomal genes, decondensation of pericentromeric structural heterochromatin, and release of genes repressed due to age-related chromatin condensation. This chromatin-modifying activity suggests the peptide may influence gene expression through epigenetic mechanisms.

Melatonin Regulation and Circadian Effects

Research on the pineal-melatonin axis has examined its effects on nocturnal melatonin secretion. A 2007 study by Korkushko and colleagues, published in Advances in Gerontology, reported that both Epithalamin and synthetic Epitalon restored the nocturnal peak of melatonin release and normalised circadian melatonin profiles in old rhesus monkeys and elderly human subjects with documented pineal insufficiency. However, an in vitro study found that acute superfusion of pineal glands with the peptide failed to increase melatonin release, suggesting the mechanism may be indirect.

Research Applications

Longevity and Aging Research

This Epitalon peptide has been studied extensively in rodent lifespan models. A 2001 mouse study by Anisimov, Khavinson, and colleagues reported slower aging and extended lifespan in female CBA mice receiving subcutaneous Epithalon from six months of age, alongside reduced tumour incidence and decelerated free-radical processes. A 2007 study in female rats found that it extended maximum lifespan by approximately 95 days under natural light conditions, though it did not change lifespan under standard lighting. These findings are conditional and regimen-dependent, with results differing between male and female rodents.

Telomere Biology Research

The 2025 Springer Biogerontology study represents the most comprehensive quantitative analysis of the compound’s effects on telomere length. Researchers treated normal fibroblast cells (IBR.3) and epithelial cells (HMEC) with 1.0 μg/mL of Epitalon daily for 3 weeks, measuring DNA, RNA, and telomerase activity. For laboratories investigating telomere maintenance mechanisms, the peptide provides a well-characterised tool compound with independently replicated results.

Retinal and Wound Healing Research

A 2025 study published in Stem Cell Reviews and Reports examined the antioxidant tetrapeptide in an in vitro model of diabetic retinopathy. Using high glucose-injured human retinal pigment epithelial cells (ARPE-19), researchers found that Epitalon restored impaired wound healing by inhibiting hyperglycemia-induced epithelial-mesenchymal transition and fibrosis. The study suggests that it may be a promising therapeutic strategy for diabetic retinopathy research, though more mechanistic investigations are needed.

Quality and Purity

Every batch of Cocer Peptides Epitalon undergoes rigorous quality control:

• ≥99% purity verified by HPLC

• Molecular weight confirmed by mass spectrometry

• Batch number matching the vial label

• Certificate of Analysis (COA) available on request

The FDA has noted that this peptide poses a risk for immunogenicity, potentially amplified by aggregation and peptide-related impurities, particularly via subcutaneous routes. Batch-level analytical documentation is therefore essential when sourcing it for research reproducibility. According to UK regulatory guidance, peptides sold for research purposes operate in a distinct category from licensed medicines, and individual buyers may purchase research peptides without legal risk under the Misuse of Drugs Act 1971.

Frequently Asked Questions

What is Epitalon?

It is a synthetic tetrapeptide with the amino acid sequence Ala-Glu-Asp-Gly (AEDG). It was synthesised based on the amino acid composition of Epithalamin, a bovine pineal gland extract. This Epitalon peptide is studied primarily for its effects on telomerase activation and telomere elongation, as documented by Creative Peptides.

What is the difference between Epitalon and Epithalamin?

Epithalamin is a pineal-derived polypeptide preparation, while Epitalon is a synthetic tetrapeptide developed from its amino acid composition. Although historically related, the two preparations are chemically distinct and their evidence should not be considered interchangeable, according to Scilit.

Is Epitalon approved for human use?

No. It has not been approved by the FDA or most Western regulatory agencies. The FDA reviewed it through the 2026 PCAC compounding process, which does not constitute therapeutic approval. This product is supplied strictly for research purposes.

What is the purity of Cocer Peptides Epitalon?

Our Epitalon is provided at ≥99% purity, verified by HPLC with third-party testing, as confirmed by PeptideMark.

How should Epitalon be stored?

Store lyophilized powder at -20°C for long-term stability. Reconstituted material should follow standard laboratory protocols.

Is this product suitable for human use?

No. This product is supplied strictly for research purposes only and is not intended for human or veterinary use. No adequately powered randomised trial has established therapeutic efficacy for this peptide, as noted by PeptIQ.

Conclusion

Epitalon represents a well-characterised research tool for investigating telomerase activation, telomere maintenance, and chromatin modification mechanisms. With its high-purity formulation and comprehensive quality documentation, this 10mg presentation from Cocer Peptides enables researchers to study the peptide in controlled laboratory settings.
