Epithalon, also commonly known as Epitalon, is a short synthetic tetrapeptide originally derived from research on the pineal gland. This small peptide consists of only four amino acid residues, which gives it excellent molecular flexibility and relatively high stability in laboratory research environments compared with longer polypeptide chains. It has become a widely studied molecule in the field of aging biology and geroscience research.

The core research interest of Epithalon lies in its ability to modulate telomerase activity in cell models. Telomerase participates in maintaining the length of telomeres located at the ends of chromosomes. Telomere shortening is closely linked to cellular senescence and age-related cellular functional decline. Laboratory studies indicate that Epithalon can stimulate telomerase expression in certain cell lines, slowing the rate of telomere attrition and delaying the progression of cellular aging. Apart from telomere-related research, Epithalon also exhibits regulatory effects on multiple biological pathways. It can exert antioxidant effects by clearing reactive oxygen species inside cells, lowering oxidative stress and reducing oxidative damage to DNA and cell membranes.

In addition, preclinical laboratory research has demonstrated its regulatory function on the endocrine system. It helps modulate the secretion rhythm of several key hormones, balancing the physiological activities associated with the pineal gland and circadian rhythm. Multiple in vitro and animal model experiments also explore its potential immunomodulatory properties, assisting in maintaining normal immune cell function and resisting age-related immune decline.

Our Epithalon is produced by solid-phase peptide synthesis technology. After peptide chain assembly, crude products go through multi-step preparative HPLC purification to eliminate truncated fragments, residual protecting groups and other organic impurities. Each production batch undergoes strict quality control procedures, including HPLC purity detection, mass spectrometry sequence verification, moisture test and appearance inspection. COA, HPLC chromatogram and MS spectrum reports can be provided for each batch to satisfy laboratory documentation requirements. The finished product adopts lyophilization technology to greatly enhance molecular stability, minimizing degradation during transportation and long-term cold storage. This product is supplied to university laboratories, biotech R&D centers and research institutions for cell senescence experiments, telomerase mechanism research, oxidative stress models, endocrine regulation and immunology related preclinical studies.
